This page provides information related to the Versal Platform Loader and Manager (PLM). 

Table of Contents

PLM Overview

The Platform Management Controller (PMC) in Versal has two Platform Processing Units (PPUs) to run Boot ROM and PLM respectively. PLM runs on the PPU Microblaze in PMC. PPU has 384 KB of PPU RAM and 128 KB of PMC RAM. PLM is responsible for doing the system initialization, booting and configuration of various devices as a part of Loader. It also takes care of secure boot which are authentication and/or decryption. After the initial boot is complete, PLM is responsible for Error Management, Partial Reconfiguration, Subsystem Shutdown/Restart, Health Monitoring and Soft Error Mitigation and remains active throughout the lifetime of the system.

During the initial boot, the Boot ROM decodes the Programmable Device Image (PDI) and loads the PLM into the PPU RAM. Once the PLM starts running, it will decode and process the rest of the PDI and boot up the system by loading the partitions present in the PDI. PLM also supports loading of the partial PDIs during run time.

Configuration Data Object

Configuration Data Object (CDO) contains set of commands which are required for configuring various components in the system. Any system configuration in Versal will come in the form of a CDO to PLM. These files are generated by the tools and are input to PLM. The CDO commands are registered by each module during module initialization phase. PLM decodes and passes this information to various modules for configuration. PLM copies the CDOs to PMC RAM in 64K chunks, decodes and processes them.

Please refer to UG1283 for PDI Specification

Modules in PLM

The PLM is designed with a modular subsystem-based configuration, and task-based services. Each functionally distinct feature is designed as a module. The PLM application layer contains the module initialization and start-up tasks. Depending on the modules selected in the configuration, different modules are initialized. Modules can register event handlers, IPI handlers, CDO commands, and scheduler events with the PLM interface layer.

Following are the list of modules present in the PLM:

  1. XilPLMI

  2. XilLoader

  3. XilPM

  4. XilSecure

  5. XilSEM

Note: XilLoader internally uses XilPDI library for loading the PDI image. Currently, XilPLMI, XilLoader and XilPDI are intended as PLM internal only libraries. Thus, APIs from these libraries are not intended to be called directly from other software layers outside of PLM.

Building PLM

PLM can be built using Vitis and XSCT. PetaLinux uses XSCT flow to generate PLM elf while generating PetaLinux project. Please refer to <tbd page> for PetaLinux flow. Also, Vivado generates a pre-built PLM with plm.elf name.

Using Vitis

Following are the steps to generate PLM elf using Vitis tool. Additionally, please refer to UG1305 to build PLM application

  1. Open Vitis

  2. Create new application project with File → New → Application Project…

    1. New Application Window will pop up as shown below.

    2. Click on “Next”. Select “Create a new platform from hardware (XSA)”, provide XSA File in “Platform” window and click on “Next”.

    3. In “Application Project Details”, Select psv_pmc_0 processor and enter “Application project name” as “plm”.

    4. Click on Next.

    5. Select “versal PLM” in Templates window and click on “Finish”.

  3. This would create PLM application with “plm_system” name along with the BSP.

  4. Right-click on “plm_system” folder and click on “Build Project” to build PLM and generate elf.

Using XSCT

Following are the steps to generate PLM elf using XSCT:

mkdir plm_ws cd plm_ws setws . app create -name plm -hw design.xsa -template "versal PLM" -os standalone -proc psv_pmc_0 app build -name plm

These steps will create and build PLM. PLM elf can be found at plm/Debug/plm.elf

Generating Boot Image

Boot image can be generated using BootGen command. We need to create a BIF file to generate Boot image. Also, please refer to UG1283 for more details on this.

  1. We already have PLM elf with us. Check the previous section to build PLM.

  2. Create and build PSM Firmware elf for PSM Microblaze.

  3. Create required applications for A72/R5, AIE, CPM etc.

  4. Create BIF file (boot.bif) with the below format

    all: { id_code = 0x14ca8093 //Add ID_CODE as per the Hardware extended_id_code = 0x01 id = 0x2 image { name = pmc_subsys, id = 0x1c000001 {type = bootloader, file = ./plm.elf} {type = pmcdata, load = 0xf2000000, file = ./pmc_data.cdo} } image { id = 0x4210002, name = lpd {type = cdo, file = ./lpd_data.cdo} {core = psm, file = ./psm_fw.elf } } image { id = 0x18700000, name = pl_cfi {type = cdo,file = ./design.rcdo} {type = cdo,file = ./design.rnpi} } image { id = 0x420c003, name = fpd {type = cdo, file = ./fpd_data.cdo} } image { id = 0x4218007, name = cpm { type = cdo, file = ./cpm_data.cdo} } image { id = 0x1c000000, name = def_subsystem { load = 0x1000, file = ./system.dtb} { load = 0x10000000, file = ./image.ub} { core = a72-0,exception_level=el-3, trustzone, file = ./bl31.elf} { core = a72-0,exception_level=el-2, file = ./u-boot.elf} { load = 0x4000000, file = ./rootfs.cpio.gz.u-boot} } image { id = 0x1c000000, name = def_subsystem { core = r5-lockstep, file = ./rpu_hello.elf} } }

Loading Boot Image on Hardware

We have created BOOT.BIN in “Generating Boot Image” section above. This image can be used to boot the Versal Hardware in any boot mode mentioned in “Boot Modes” section. In this section, we will see the steps to boot Versal in JTAG and SD boot mode.

In JTAG Boot Mode

Following are the steps to boot Versal Hardware in JTAG boot mode:

  1. Set the boot mode pins to JTAG on Hardware, power on and connect to board.

  2. Launch xsdb and connect to Hardware.

  3. Once the Hardware is connected, you will see the following targets when “ta” command is issued on xsdb terminal.

  4. Issue the following command to program the Hardware in JTAG boot mode.

  5. Once the Hardware is booted, PLM, PSM and the other application prints will come on the console in the sequence of the images mentioned in BIF file.

  6. Please refer to Debugging Tips section for more details on how to read PLM memory log and other debug tips.

In QSPI Boot Mode

Following are the steps to boot Versal Hardware in QSPI boot mode. Please refer to UG908 for more details.

  1. Initially, boot Versal in JTAG boot mode till U-Boot.

  2. Execute the following command in U-Boot on serial console to probe the flash device

  3. On xsdb terminal, execute the following commands to write QSPI boot image to DDR

  4. Then on serial console, execute the following commands in U-Boot to erase the flash memory and write the boot image to QSPI Flash

  5. Change the boot mode to QSPI and boot. It will boot the Versal Hardware in QSPI boot mode and loads the boot image that we have written to QSPI flash using the above mentioned steps.

In OSPI Boot Mode

Following are the steps to boot Versal Hardware in OSPI boot mode. Please refer to UG908 for more details.

  1. Initially, boot Versal in JTAG boot mode till U-Boot.

  2. Execute the following command in U-Boot on serial console to probe the flash device

  3. On xsdb terminal, execute the following commands to write OSPI boot image to DDR

  4. Then on serial console, execute the following commands in U-Boot to erase the flash memory and write the boot image to OSPI Flash

  5. Change the boot mode to OSPI and boot. It will boot the Versal Hardware in OSPI boot mode and loads the boot image that we have written to OSPI flash using the above mentioned steps.

In SD0/SD1/eMMC Boot Mode

Following are the steps to boot Versal Hardware in SD0 boot mode. Please refer to UG908 for more details.

  1. Initially, boot Versal in JTAG boot mode till U-Boot.

  2. Execute the following command in U-Boot on serial console to probe the emmc device

  3. On xsdb terminal, execute the following commands to write the boot image to DDR

  4. Then on serial console, execute the following commands in U-Boot to write the boot image to eMMC device

  5. Change the boot mode to SD0_LS/SD1_LS/SD1/eMMC and boot. It will boot the Versal Hardware in SD/eMMC boot mode and loads the boot image that we have written to SD/eMMC flash device using the above mentioned steps.

Note: The boot image can be directly copied to SD card and boot as well.

Secondary Boot

Any of the boot devices supported for secondary boot mode can be used as secondary boot device. Please refer to UG1283 for more details on secondary boot. Following are the steps for secondary boot process:

  1. PLM elf, LPD, Topology and PMC CDO and PSM elf must be part of primary boot image and any other images can be part secondary boot image.

  2. Specify the secondary boot device in the bif file. For example, if QSPI is chosen as secondary boot device and the secondary boot image stored at 0xC000000 location in QSPI, specify the same in primary boot image bif file before providing any image. Example bif file for primary boot PDI:

     

  3. When boot_device parameter is found in bif, BootGen will place the secondary boot device and secondary boot image details in image header table in meta header.

  4. When PLM sees this information, it will initialize the secondary boot device if it is other than primary boot device and will read the specified location and loads the secondary boot image.

  5. Example bif file for secondary boot PDI is below. Secondary boot PDI need to be generated and need to be copied to the boot device location as mentioned in the primary boot bif file. In this case, secondary boot image need to be copied to 0xC000000 location in QSPI Flash.

PLMI

The PLM Interface (XilPLMI) is a low-level interface layer for the PLM main application and other PLM modules. XilPLMI provides the common functionality required for the modules that run with PLM. Each new module can register itself with the supported command handlers which are executed based on the request received from other modules or from other subsystems. For more details on PLM modules, please refer to UG1304.

The XilPLMI layer provides the following functionalities:

  • Interface for parsing CDO commands and execution of the corresponding CDO command handler of any module.

  • Implementation for general PLM CDO commands

  • Interface for registering handlers for commands that can be part of CDO/IPI

  • Interface for scheduler timer events

  • Debug print levels and common utilities

  • Task Dispatcher

  • Interface to set error actions and register notifications for error events

  • Framework to update the PLM health periodically

  • Logging PLM terminal prints and the image trace log to the memory

Please refer to CDO spec for the list of CDO/IPI commands supported by XilPLMI.

IPI Handling

IPI is a key interface between PLM and other processor entities on Versal. PMC has a dedicated IPI channel assigned to it. PLM uses this IPI channel and its associated buffers for communication, which is initiated by other masters on Versal to PLM.

Data that is sent through IPI follows the same format of CDO. PLM uses IPI driver to send and receive IPI messages. PLMI implements IPI manager layer over the driver and it takes care of dispatching the IPI messages to the registered modules based on Handler and API ID in the IPI header.

PLMI implements IPI APIs provided for other Modules to perform the following actions:

  • Initializing and enabling IPI interrupts

  • Send IPI Message/response to a processor

  • Receive IPI Message/response to a processor

  • Dispatch received IPI message to corresponding registered module

Note: CRC can be enabled for IPI messages by setting ENABLE_IPI_CRC_VAL to 1U in xipisu.h file. This will add CRC validation check for IPI to/from communication. Please note that this setting need to be done in all application libraries for the Versal boot and post boot to work without any issues.

Task Modeling in PLM

PLM provides a very simple run-to-completion time-limited priority task loop model to get real-time behavior. This means that the main program is a simple loop that looks up the next task (typically a pointer to a function to be executed with a corresponding context data structure) from a queue of tasks and calls the function (executes the task) with the context as a parameter. Any interrupt that occur while the task is running, will obviously interrupt the execution, but since you are only allowed to do extremely simple things at interrupt level (i.e., disable interrupt and add a new task to the task queue), the task is logically executed in one chunk.

The complexity with the run-to-completion model comes when a particular task needs to run longer. If that happens, the task needs to be split into multiple events. There are three priority task queues, with Critical, High and Normal priority, Task dispatcher will check the priority queues in order and execute the Critical priority task handlers first. After executing task handler, dispatcher will check the task queues again and execute the next handler. If there are multiple tasks present in same queue, tasks will be executed one by one. All the tasks run to completion till task handler returns (i.e., there is no preemption). With no preemption, there will not be any need for locks and synchronization issues. Once the task is completed, it will be removed from the queue.

The priority order of the tasks are as below:

  1. Critical priority tasks (XPLM_TASK_PRIORITY_CRITICAL)

  2. High Priority tasks (XPLM_TASK_PRIORITY_0)

  3. Normal Priority tasks (XPLM_TASK_PRIORITY_1)

The general specifications for each PLM module are

  1. Run nothing in interrupt context; instead, add the necessary priority task to the task queue.

  2. To allow PLM to move on to the next high-priority task, the running task must not take longer time.

  3. No task should obstruct resources such as DMAs or CFI for longer duration.

Since PLM supports three priority tasks (Critical, High and Normal priority), below example shows how the user can create a high priority task within PLM

In the above example code, XPLM_TASK_PRIORITY_0 is passed to the XPlmi_TaskCreate function along with the task handler to create a task with high priority. Similarly, If user wants to create a Normal priority task, XPLM_TASK_PRIORITY_1 needs to be passed as priority argument for XPlmi_TaskCreate function.

Scheduler

Scheduler is a simple timer-based functionality to support execution of periodic/non-periodic tasks. A scheduler is required by modules such as XilSEM to support periodic tasks such as SEU detection scan operations. Scheduler also supports Critical, High and Normal priority tasks. The Critical priority tasks are given priority over High and Normal priority tasks.

Adding a task to scheduler

Tasks are functions which take void args and return the state of the task handler. Currently, PLM has no way to check that the task returns in a pre-determined time, so this needs to be ensured by the task design. Let us consider a task which prints out a message:

If we want to schedule the above task to occur every 100ms with highest priority, the following code can be used:

Removing a task from Scheduler

If we want to remove the previously scheduled task from the scheduler task list, the following code can be used:

Image Store

The Image Store feature allows PDI files to be stored in memory (DDR) and later be used to load specified images within the PDI. This is intended to allow partial reconfiguration, subsystem restart, etc without depending on external boot devices.
Also, this Image Store can be used as the Secondary Boot Device to use the PDI’s saved in the DDR.

PLM will have access to a dedicated DDR Location for storing of these user requested PDI's, the allocated DDR location address and size is Populated in the pre-defined RTCA region space for PLM to get the Image Store config details.

Currently user need to add below config at the end of “pmc_data.cdo” file before building the Boot PDI.

write 0xF2014288 <High 32bit addr> #Image Store Address High 32bit
write 0xF201428C <Low 32bit addr #Image Store Address Lower 32bit
write 0xF2014290 <Allocate size> #Image Store Allocated Size

*This above size which we give here is basically the total Image store memory allocated where multiple PDI’s are stored once the PDI add request is made.
Eg:

A new <PDI ID> field is added to the Add & Remove Image Store IPI command

Command: Add PDI to ImageStore

Reserved[31:25]=0

Security Flag[24]

Length[23:16]=4

XilLoader=7

CMD_ADD_IMG_STORE_PDI=9

PDI ID

High PDI Address

Low PDI Address

PDI Size ( In Words )

This command adds PDI address to the list of Image Store PDIs that are maintained by PLM. During restore or reload of a image, PLM checks this dynamically added list of PDIs first to get the required image and in case of any failure, it falls back to next possible. If no valid entry is present, it uses boot pdi, which is the first entry in the list. 

Response: Add PDI to ImageStore

Status (XST_SUCCESS / XLOADER_ERR_PDI_IMG_STORE_CFG_NOT_SET / XLOADER_ERR_PDI_IMG_STORE_FULL)

 

Command: Remove PDI from ImageStore

Reserved[31:25]=0

Security Flag[24]

Length[23:16]=1

XilLoader=7

CMD_REMOVE_IMG_STORE_PDI=10

 PDI ID

This command removes PDI address from the list of Image Store PDIs that are maintained by PLM.

Response: Remove PDI from ImageStore

Status ( XST_SUCCESS / XLOADER_ERR_PDI_ADDR_NOT_FOUND)

Also we can add the PDI via Boot Bif which will be part of CDO command (write image store) , in example below 2 pdi's will be added as a part of Image Store, 

Bif Example format below

write_image_store_pdi_1:
{
id_code = 0x14ca8093
extended_id_code = 0x01
id = 0x1
image
{
name = subsystem
id = 0x1c000008
partition
{
id = 0x9
core = a78-0
file = a78_0_ddr.elf
}
}
}

new_bif: {

id_code = 0x14ca8093
extended_id_code = 0x01
id = 0x1

image
{
name = pmc_subsys
id = 0x1c000001
partition
{
id = 0x2
type = bootloader
file = ./plm.elf
}
partition
{
id = 0x3
type = pmcdata,load=0xF2000000
file = ./pmc_data.cdo
}
}

image

{

  name = IMAGE_STORE

  id = 0x18700000

  partition

  {

   id = 0xb15

   imagestore = <Pdi id>

   section = write_image_store_pdi_1

  }

  partition

  {

   id = 0xb15

   imagestore = <Pdi id>

   file = partial.bin

  }

}

}

Image Store can also be used the Secondary Boot Device , as shown below via Boot Bif.

 boot_device { imagestore, address = <Pdi id> }

e.g : Secondary Boot from Image Store

As show below PLM will process the PDI and add the Images with PDI ID 10,12 to the Image Store and after that will check if any Secondary Boot Mode is specified and sees source is Image Store with PDI ID 12,

it then starts processing the partial PDI from Image Store.

new_bif: {

id_code = 0x14ca8093
extended_id_code = 0x01
id = 0x1

boot_device { imagestore, address = 12 }

image
{
name = pmc_subsys
id = 0x1c000001
partition
{
id = 0x2
type = bootloader
file = ./plm.elf
}
partition
{
id = 0x3
type = pmcdata,load=0xF2000000
file = ./pmc_data.cdo
}
}

image

{

  name = IMAGE_STORE

  id = 0x18700000

  partition

  {

   id = 0xb15

   imagestore = 10

   section = partial2.bin

  }

  partition

  {

   id = 0xb15

   imagestore = 12

   file = partial.bin

  }

}

}

Error Handling in PLM

Error Management HW

The Versal device has a dedicated error handler in PMC and PSM to aggregate all the fatal errors across the SoC and handle them. Refer to the TRM/Arch Spec for details. All fatal errors routed to PMC/PSM Error Manager can either set to be handled by HW ( and trigger a SRST/PoR/PS Error Out) or trigger an interrupt to PMC/PSM.

Error Management in PLM

The PLM Error Manager provides APIs for assigning a default error action for errors present in PMC and PSM in response to an error. During initialization of the PLM modules, the PLMI initializes the Error Manager, enables errors, and sets error action for each error in accordance with the Error Table structure defined in the xplmi_err.c file.

Following are the error actions supported by PLM for each error in PMC and PSM:

  1. POR - Power On Reset

  2. SRST - System restart

  3. CUSTOM (Not supported through CDO)

  4. PS Error Out - Error Out

  5. Subsystem Shutdown - Shutdown of a specific subsystem

  6. Subsystem Restart - Restart of a specific subsystem

  7. No Action

  8. Register notifier - Notifying a specified subsystem when error occurs

Error Management CDO commands

The following CDO commands are supported by the PLM error management module.

Set Em Action

Command: Set EM Action

Reserved[31:25]=0

Security Flag[24]

Length[23:16]=3

EM=8

CMD_SET_EM_ACTION=1

Error Event ID

Reserved

Action

Error Mask

This command is used to set error action for the specified Error Event ID and Error Mask. Refer to xil_error_node.h file for the list of Error Event IDs supported and Error Masks supported. Currently error management APIs are not supported over IPI.

Actions:

  • Invalid – 0x0

  • Power On Reset  – 0x1

  • System Reset – 0x2

  • Custom Action – 0x3 (Not supported)

  • Error Out – 0x4

  • Subsystem Shutdown – 0x5

  • Subsystem Restart – 0x6

  • None – 0x7. Disable all actions on the Event and clear error status

Note: For PSM error events, the command returns failure if LPD is not initialized.

Register Notifier for EM Events

Command: Register Notifier

Reserved[31:24]=0

Length[23:16]=4

PMC_LIBPM=2

CMD_PM_REGISTER_NOTIFIER=5

Node ID (Error Event ID)

Event Mask (Error Mask)

Argument 1

Argument 2

EM supports notifying a subsystem when registered error occurs, using the register notifier API supported by XilPM. Use this command to register for notifications when registered errors occur. Refer to xil_error_node.h for a list of supported error event IDs and error masks.

  • Node ID: Can either be a Device ID or Error Event ID. Use an Error Event ID for registering error events.

  • Event Mask

    • For Device ID: Event Type

    • For Error Event ID: Error Mask

  • Argument 1

    • For Device ID: Wake

  • Argument 2

    • For Device ID: Enable

The register notifier for an event of an error event ID enables the error event by clearing the corresponding PMC/PSM_ERR#N_STATUS bit and writes to the corresponding PMC/PSM_IRQ#N_EN. The notifier returns an event index (which is a bit that notify callback sets) to indicate the occurrence of the event.

The register notifier command works with the notify callback command. With register notifier command, multiple subscribers (A72, R5) can register for a single error event notification.

For example, register notifier of error node GT_CR error event clears PMC_ERR1_STATUS.GT_CR, enables PMC_IRQ1_EN.GT_CR, and returns a number, for example, 5. Notify callback sets bit 5 of the event status to indicate that the GT_CR error has occurred.

 

Notify Callback

Command: Notify Callback

Reserved[31:24]=0

Length[23:16]=4

PMC_LIBPM=2

CMD_PM_NOTIFY_CALLBACK

Node ID (Error Event ID)

Event Status (Error Mask)

On notify callback of an event of Error Event ID, the Error Node is disabled. For example, notification of the Error Node GT_CR error event disables the error by writing to PMC_IRQ1_DIS.GT_CR. You must re-register to be notified again.

For more information of registration/un-registration of error events, see Event Management Framework section in UG1304.

PSM errors handling by PLM

The HW error actions supported by PMC EAM for PMC errors are SRST, POR, IRQ (Interrupt to PMC Microblaze) and Error Out. And the HW error actions supported by PSM EAM for PSM errors are PSM_CR (PSM errors routed to PMC Microblaze as PSM_CR), PSM_NCR (PSM errors routed to PMC Microblaze as PSM_NCR), IRQ (Interrupt to PSM Microblaze) and SRST.

Even though these are the HW error actions, PLM supports the error actions mentioned in above section. So, any error can be configured to have the error action supported by PLM. Please refer to Additional information column in the table below to know the restrictions on the error actions for any error.

Since all the PLM supported error actions cannot be handled by the PSM HW supported error actions, the PSM errors are routed to PMC Microblaze either as PSM_CR or as PSM_NCR. So, all the PSM EAM errors are handled by PLM only. If a user selected error action for any PSM error matches with the PSM_CR error action, then PLM configures that PSM error as PSM_CR. If the user selected error action doesn’t match with PSM_CR error action, then PLM configures that as PSM_NCR and PLM executes the configured error action.

Note: Error action configuration for PSM errors is allowed only when LPD is initialized. If LPD is uninitialized, the PSM errors cannot be configured or handled

SW errors

The SW errors are the extended feature of the PLM error management. User can add any error to the SW errors list. These can also be configured through EAM CDO command. All the error actions are supported and handled by PLM. For the SW error to be handled by PLM, “XPlmi_HandleSwError" API need to be called from SW whenever there is an error occurrence.

For example. the “PLM_EXCEPTION” is not in the PMC EAM errors. So, to have any error action when any exception occurs, this is listed as one of the SW errors in the ErrorTable. And in the PLM Exception Handler, PLM calls “XPlmi_HandleSwError" to execute the configured error action. Please refer to https://github.com/Xilinx/embeddedsw/blob/master/lib/sw_apps/versal_plm/src/common/xplm_proc.c#L115 code for the same. Also, please refer to xil_error_node.h for the Error Node ID for SW errors and the list of SW errors.

SRST

The default error action for PSM_CR is SRST. PLM allows changing the error action for this error only once. If user tries to change it, PLM gives “XPLMI_CANNOT_CHANGE_ACTION" minor error as response. And the allowed error actions are HW (SRST, POR and Error Out) error actions only. If other error action is specified, PLM gives “XPLMI_INVALID_ERROR_ACTION" minor error as response.

Configuration of EAM errors through a CDO

Since the tools support to configure the EAM errors is not yet added, this section describes how they can be configured through a CDO. Below snippet shows the example EAM CDO which can be modified as per the requirement, can be included in the BIF as a CDO and PDI can be generated.

Loader

PDI contains all the images that must be loaded into the system. PLM reads the PDI from the boot device and loads the images to the respective memories based on the image header. For more details on PDI, refer to UG1304.

Following are the responsibilities of XilLoader:

  • Boot device initialization

  • Interface for modules to load/start/look up the image present in PDI

  • Interface with XilPDI to decode and validate images present in PDI

  • Support secure boot loading using XilSecure module

  • Subsystem bring up by calling XilPM

Please refer to CDO spec for the list of CDO/IPI commands supported by XilLoader.

PM

Platform Management (XilPM) is a library that provides interfaces to create and manage subsystems, MIO, Clocks, Power and Reset settings of nodes. The following table provides the list of commands supported by this module. For details about Platform Management, refer to the Chapter 10: Versal ACAP Platform Management in UG1304

Secure

The XilSecure library is a library of security drivers that access the hardened cryptographic cores to support the AES-GCM 256-bit/128-bit engine, the RSA/ECC engine that supports RSA-4096, RSA-3076, RSA-2048 as well as ECDSA NIST P-384 and NIST P-521, and the SHA3/384 engine.
For more information, see Chapter 9: Security in UG1304.

Sem

The Xilinx Soft Error Mitigation (XilSEM) library is a pre-configured, pre-verified solution to detect and optionally correct soft errors in Configuration Memory of Versal ACAPs.
See the OS and Libraries Document Collection (UG643) for more information.

PLM Build Flags

PLM Feature Configuration

In Zynq UltraScale+, for applications FSBL and PMUFW changing of configuration (enable/disable certain feature(s)) was possible through Vitis GUI (where we can define or undefine), same could be done in command line using -D or -U as parameter to make (for defining or undefining). 

In Versal, most of the PLM application functionality is distributed to various libraries and configuration of various features is done in XilPLMI library. Hence, these features shall be enabled/disabled through Board Support Package Settings. This enhancement in PLM is done in 2022.1

Enabling of certain features (e.g. boot modes, SEM feature, UART debug) as referred here is w.r.t. enabling the corresponding support in PLM. For these features to be fully enabled and available, the hardware configuration(s) corresponding to these features too should be available. However, disabling these features in PLM results in overall disabling irrespective of the corresponding hardware configuration.

Below table lists the PLMI library configuration options, their description and default configuration:

  • Click on the Modify BSP Settings… button as shown in below screen.

  • All the configurable libraries will be shown with tick mark in the Supported Libraries frame.

  • Click on the xilplmi library in the GUI as shown in the below screen. All the configurable parameters for the library xilplmi are now visible under column "Name". By default "Value" and "Default" fields show same configuration.

  • Click on Value column against configurable to list the available options against configuration. Change the selection as appropriate and click on OK button. Wait until the BSP generation happens as per the selection.

  • Now build the PLM project as usual.

PLM Feature Configuration through xsct

The below snippet shows steps involved in initially building the PLM with default configuration, then changing the debug level to debug info and regenerate BSP and rebuilding PLM, and then finally changing the debug level back to general (which is default), enabling the USB boot mode and regenerate BSP and rebuilding PLM. Refer above table for the different configuration options.

PLM Feature Configuration for PetaLinux

Refer above table for the different configuration options. Below example shows how to enable USB boot mode (which is disabled by default).

Debugging Tips

PLM throws XYZ error code when any error occurs. This error code will also be stored in PMC_GLOBAL FW_ERR (0xF1120100) registers.

Reading PLM memory log and interpreting PLM prints

By default PLM prints are stored in PMC RAM at address 0xF2019000. Maximum size allocated for PLM print log memory is 16KB. After that PLM will overwrite the existing prints.

From xsdb, we can read and view the prints using either of the following three commands.

If prints are read using first command, user can open uart.bin in vi or any editor and see the prints.

Below is the example log for the PLM prints:

"[X]" at the start of the print signifies the total cumulative time taken in ms from the start of PLM to that print statement.

"X ms for Partition#: Y, Size: Z Bytes" - this print indicates time taken for loading partition number Y of size Z bytes is X ms.

ROM time is from start of ROM to PLM start point.

"[X] Total PLM Boot Time" indicates that the total PLM boot time in ms.

PLM error code format:

0xXXXX_YYYY is the error code format.

XXXX - Major error code - PLM/LOADER/XPLMI error codes as defined in xplmi_status.h file in XilPLMI library

YYYY - Minor error code - Libraries / Drivers error code as defined in corresponding modules.

Below table describes the major error code decoding for CDO Command failures(Supported from 2020.2):

Please refer https://github.com/Xilinx/embeddedsw/blob/master/lib/sw_services/xilplmi/src/common/xplmi_modules.h#L61 for module IDs supported by PLM

0x2XYZ - 0xYZ indicate handler ID of the CDO command. Handler IDs can be checked in CDO spec against the module

PLMI handlers: Please refer to https://github.com/Xilinx/embeddedsw/blob/master/lib/sw_services/xilplmi/src/common/xplmi_generic.c#L1985 for handlers supported in PLMI (GENERIC) module.

Ex: 0x223E

0x223E - 0x2 indicates failure in CDO command

0x223E - 0x2  indicates command failed in PM Command.

0x223E - 0x3E indicate handler ID of the PM command which is PM_INIT_NODE.

Debugging PLM errors

Preferred Debug Level
Enable PLM_DEBUG_INFO Macro for more verbose detailed logs.

Enabling debug mode in PLM

PLM_DEBUG_MODE macro in xplmi_config.h file can be enabled to enable the debug mode in PLM. Enabling this flag disables soft reset and memory clearing in case of error during initial PDI loading. This will be helpful in maintaining the system state for debugging when any error occurs. If this flag is not enabled, PLM does a soft reset and there is a chance that PLM first error gets overwritten by next error code of PDI load.

Following are the register writes required to enable DAP in case security is enabled. These register writes need to happen at the start of PLM. This DAP CDO need to be included in BIF to merge it as part of PMC CDO.

Further data that can help in debugging:

  • Reading the device status from xsdb with the following commands

     

  • PLM State

     

  • And UART console or memory log

  • If UART is enabled in the design and no prints on the terminal, then PLM has failed before LPD configuration. PLM might have failed in PMC or LPD CDOs or boot device initialization.

The following table lists various error codes present in PLM and provides additional information on next steps:

  1. Verify with a second Versal ACAP device or board if available, to eliminate board setup for these errors. If error persists, contact Xilinx®

  2. Verify voltages and temperatures are within device operating specifications and reboot the device

  3. This can occur when PDI data is corrupted from the boot device. Enable checksum to detect any PDI errors.

  4. Check if older version of PLM elf is used with new CDO files. Check “PLM Compatibility between releases” section to verify the compatibility of PLM and CDOs files version.

  5. Please check the design if proper configuration is selected in Vivado for IO peripherals (QSPI, OSPI, SD, eMMC, UART) and if same design is used to generate PLM elf. Design parameters can also be verified in xparameters.h to know if they are exported properly or not from xsa.

  6. Please check the design if proper configuration is selected in Vivado and it is properly reflected in CDO files generated

Error when invalid QSPI connection listed other than Single, Dual, stacked

Check if the QSPI connection mode is selected properly in CIPS and connections are proper on board.

There are other cases where this error code can come. If PLM finds any error, PLM does a soft reset in non-JTAG boot modes. In those cases, there can be chances where same boot image is booted again with different multiboot value.

ROM checks for 512M in parallel mode, so if QSPI flash size is 256M, address wraps around to 0x0 and it boots the same image.

PLM checks for multiboot value and flash size. As it is beyond flash size, PLM fails with QSPI error.

To debug the issue properly, enable PLM_DEBUG_MODE to debug the system at first PLM error.

Source Level Debugging with Vitis

Prerequisite

Compilation Settings

Debugging software requires as minimum as possible optimizations to be used at build time in order to ensure that translation from C files to the final assembly code is as close as possible. This would translate on a proper debugging experience where stepping through the C files is performed in the written order. Any optimization in the build means that stepping through the code might end up jumping through the lines as the final application does not correspond 1:1 to the code written in C. The different components of the PLM have different build settings as shown below.

Application

The PLM application code is configured without optimization options, so there is no need of modifying anything in the setting to get a proper debug experience.

Board Support Package

The BSP is configured with -O2 optimization level, and LTO optimization enabled (-flto -ffat-lto-objects) in order to reduce the size of the library as much as possible. As mentioned before, this means that any attempt to debug code within the library would be almost impossible. Unfortunately removing the optimization is not possible at BSP level as that would lead to a size overflow in a way that the PLM would not fit in the memory.

Removing optimization ( File level example )

The board support package build architecture is designed in a hierarchical way, so that each library/driver has it's own Makefile that inherits the variables set in a higher level. Removing or reducing the optimization level on the PLM BSP requires modifying the Makefile of individual components, either changing the settings for the whole component or individual files.

As an example the Makefile for XilPlmi library can be modified in the following way at File level:

Default Makefile uses the same compilation options for all the C files in the directory, therefore to compile a single file with different options a new target has to be defined in the Makefile. In the bellow case xplmi.c is build using custom flags(highlighted below) rather than using the EXTRA_COMPILER_FLAGS defined for the whole library.

clean:
rm -rf $(LIBPLMI_DIR)/${OBJECTS}
rm -rf ${RELEASEDIR}/${LIB}

$(LIBPLMI_DIR)/xplmi.o: $(LIBPLMI_DIR)/xplmi.c $(INCLUDEFILES)
$(COMPILER) $(COMPILER_FLAGS) -g -ffunction-sections -fdata-sections -Wall -Wextra -Og $(INCLUDES) -c $< -o $@

$(LIBPLMI_DIR)/%.o: $(LIBPLMI_DIR)/%.c $(INCLUDEFILES)
$(COMPILER) $(COMPILER_FLAGS) $(EXTRA_COMPILER_FLAGS) $(INCLUDES) -c $< -o $@

Remember that rebuilding the platform project does not take into account any changes in the Makefile. A complete clean + build process is required. Additionally the PLM application needs to be rebuild as well to use the latest library files generated by the in the platform build process.

Debug Procedure

Configuring the Target Connection Details

Under Debug Configurations → Single Application Debug ( Create New Configuration ) as shown below

Choose Debug Type - “Attach to running Target” , Connect Type - Local (Direct Connection)/ New (for Remove Target Setup)

Connect Type - Local (Direct Connection)

Connect Type - New (for Remove Target Setup)

Enter the host name details with port # as example below

 

Apply above configuration and continue to debug, following view should get populated ( Left side panel showing the Subsystem List )

Open xsct console and list targets using “ta”

and select target Versal by “ta 1” command as below

Loading the Boot PDI and Mapping PLM elf symbols

device program <pdi file> - To download PDI via Jtag

Select ppu core target, stop and execute below command to map the symbols

memmap -file <plm.elf> - To map symbols

Setting breakpoints , step over , step in / out via options available in Vitis Tool / Menu Bar

 

Debugging via JTAG ( *2 xsdb instance)

Vitis IDE

  1. After placing a breakpoint where needed, select the target PPU, and map the "plm.elf" as mentioned in above procedure

    1. ta 9

    2. memmap -file plm.elf

    3. Stop the ppu core and run again for Vitis to sync with Hardware Target

    4. Disable the Jtag Lock with below command

      1. “configparams config-jtag-lock 0”

    5. Now open second xsdb instance & execute below steps

      1. Connect to HW { Local / Remote url }

      2. Increase the default timeout(*value in milli sec) with below command

        1. configparams default-config-timeout 300000

      3. Program the device with boot pdi - this will make to hit the set breakpoint in IDE

        1. device program <boot pdi>

    6. We can see that in the Vitis IDE breakpoint is Hit, user can continue to further debug PLM

Debugging via DDR ( JTAG Download)

Load Partial PDI to DDR[eg: dow -data <partial pdi> 0x100 (ddr address)] and use the IPI commands to process this PDI

and put breakpoints in PLM for stepping in code.

Debugging via QSPI/OSPI/SD/eMMC

Add while loop in PLM main to get control of the core , to map the Symbols and continue further debug.

Debugging MB Core Dumps

Microblaze Core Dumps are logg’d by the PLM running on the MB core in the event on any exception, there could be various types of exceptions (Refer Below Table “ESR EC Encoding”) which could be triggered,

Some examples are shown below explaining the possible causes and solutions to address them.

FAQs

How is PLM different from ZU+ FSBL?

The biggest difference is that FSBL either stops running after it hands-off to another application or keeps running in a loop after finishing its job. It does not service any interrupts after that. PLM can reload images, can load partial PDIs and service interrupts. PLM can be viewed as combination of FSBL and PMUFW of ZU+.

What else is different in PLM, architecturally?

In addition to handling configuration through CDOs (rather than psu_init), below are few other architectural differences in PLM:

  • Task based loop - PLM application is mostly task dispatcher

  • Modular/library based design to enable re-usability of modules of code across different applications

  • PDI loading and subsystem restart is moved to XilLoader library. It was part of FSBL source code in ZU+. Subsystem bring up and power management is part of XilPM library, it was done by PMU Firmware in ZynqMP.

PLM application as such appears much smaller. Where is other code part of PLM?

Bulk of PLM’s code is in libraries like XilPLMI, XilLoader, XilPDI, XilSecure and XilPM.

Why two components: PLM and PSM Firmware? What type of code will be present in each of these?

PLM is the main component of Versal device which is responsible for boot and run time management (Platform management, Error management, Partial reconfiguration, Subsystem restart, etc) of the device.

PSM Firmware on the other hand is responsible for run time management of PS block in the Versal device. It manages the PS subsystem during run time in communication with PLM.

What is PDI?

PDI stands for Programmable Device Image which is generated by BootGen and is similar to boot image of ZU+. BootGen takes PLM, configuration (CDOs) and subsystems elfs(PSM Firmware, ATF, U-Boot, R5 apps, etc) as an input and creates PDI file which can be decoded by RCU and PPU. RCU decodes this PDI and loads PLM to PPU RAM and handsoff to PPU processor. PLM running on PPU further decodes this PDI file (which is Boot/Full PDI), and loads the partitions.

What is partial PDI and how is it different from Boot PDI?

A Boot PDI or a full PDI contains PLM, board specific bitstreams and CDOs, PSM Firmware, ATF, U-BOOT, Linux, system.dtb, applications to be run on A72 or R5. A partial PDI can contain one or more of these except PLM. A partial PDI is always loaded after a boot PDI.

Is any board specific configuration present in PLM?

Board specific code should come in form of CDOs. PLM does not have any board specific code.

What are the various hooks provided in PLM code?

XPlm_HookBeforePlmCdo,  XPlm_HookAfterPlmCdo and XPlm_HookAfterBootPdi are the hooks provided in PLM code. These hook functions are provided to add any user code as needed.

What Secondary Boot modes are supported in PLM?

QSPI24, QSPI32, SD0, SD1, EMMC, SD1_LS, USB, PCIe and OSPI are the secondary boot modes supported. Please refer to UG1283 for bootgen secondary BIF attributes.

What secure features are supported in PLM?

Encryption, authentication, checksum and authentication + encryption.

SEM, STL – How these safety related libraries of PLM are different?

SEM is for detecting/correcting  SEU errors at PLM startup time  and in run time, SEM does the scanning on CRAM/PL and NPI for any SEU errors. SEM also does the period scanning based on the customer requirement. This is included as static library in PLM.

STL is safety test library to detect any HW failures at run time, STL also run periodically by comparing HW Register context at regular intervals. STL integration to PLM will be delivered through lounge access.

What action does PLM take when any error occurs?

If the error occurred before Boot PDI load is completed, PLM dumps the required error registers. And if the bootmode is other than JTAG and PLM_DEBUG_MODE macro in xplmi_config.h file is not enabled, PLM updates the multiboot register and performs SRST. Otherwise, PLM takes the error action as per the configuration of Error Manager.

And when partial PDI load fails, PLM prints the error code on console and memory based on the print levels enabled.

What are the different error actions by PLM Error Manager?

The supported error actions by PLM for each error as of 2021.2 are SRST, POR, Error Out, Subsystem shutdown, Subsystem restart and Register notifier.

Please refer to Error Manager section in Chapter 8 on UG1304 for more details on register notifier error action.

What PR (Partial Reconfiguration) support is present in PLM?

PR from DDR, QSPI, SBI JTAG and SMAP sources is supported in PLM.

How is Readback triggered by user? What all can be readback?

CFI data and NPI data can be readback using PLM. Readback can be triggered by user with DDR, SBI_JTAG or SMAP as sources.

Since PMC doesn’t have a watchdog timer in PMC Domain, how to realize the functionality of same?

PLM has a framework to update the PLM health status periodically by toggling the Multiplexed I/Os when external Watchdog Timer is used. User can enable WDT by using Set PLM WDT parameters CDO command and can select PMC/LPD MIO and periodicity in milli seconds. PMC MIO is preferred over LPD MIO because when LPD MIO is selected, WDT will be disabled when the PS is down. Before running the Set PLM WDT CDO command, the MIO need to be configured as GPIO in corresponding CDO (PMC/LPD).

What is the current foot print of PLM? Is there any free space available to integrate X code with PLM?

Please refer to PLM Foot Print section above for PLM foot print details and it is expected to grow in the coming releases. Users can disable the unused drivers and modules using MACROs present in xplmi_config.h and add their own code. Current compiler optimization for Application is -O0 and for BSP it is -Os.

How to enable boot time measurements in PLM?

PLM_PRINT_PERF macro which is present in xplmi_config.h file in XilPLMI library enables boot time measurements in PLM. This macro is enabled by default right now.

Design Guidelines

Please make sure to follow the below design guidelines

  1. PMC NoC should be connected to AIE to have successful AIE zeroization.

    1. If not connected PLM will fail with a hang while processing ai_engine_data.cdo

  2. PMC NoC should be connected to DDR to download any PS images like uboot targeted for DDR

    1. If not connected PLM will fail downloading DDR images

  3. If APU need to access DDR, PS CCI ports are mandatory

  4. IPI Requirements

    1. PMC and PSM IPI is mandatory for PLM-PSM communication

      1. For PS(FPD), CDO to work properly, IPI is required for PMC - PSM communication.

    2. APU IPI is mandatory for PLM-APU communication for uboot to work

  5. Sysmon OT temperature settings should be properly selected. (Not valid from 2020.1)

    1. PLM default programming for OT temperature alarm is SRST. So, proper sysmon OT temperature setting should be done in Vivado to avoid any SRST at cold temperatures.

Invalid QSPI connection. Check the QSPI connection (Single Vs Parallel Vs Stacked).

There are other cases where this error code can come. If PLM finds any error, PLM does a soft reset in non-JTAG boot modes. In those cases, there can be chances where same boot image is booted again with different multiboot value.

ROM checks for 512M in parallel mode, so if QSPI flash size is 256M, address wraps around to 0x0 and it boots the same image.

PLM checks for multiboot value and flash size. As it is beyond flash size, PLM fails with QSPI error.

To debug the issue properly, enable PLM_DEBUG_MODE to debug the system at first PLM error.

aborting, 1 pending requests...PLM stalled during programming.

If PLM has PLM_DEBUG_DETAILED debug log level enabled and the PDI is being loaded using JTAG SBI this issue might occur. This is because the default timeout of device program is targeting the generic use case of PLM_DEBUG log level, and with DEBUG_DETAILED the PLM load time drastically increases due to huge number of prints. This results in a timeout from xsdb which gives this error.

Increase the timeout with below command on xsdb when PLM_DEBUG_DETAILED log level is enabled in PLM.
"configparams default-config-timeout 300000" 

Error Code: 0x256000F4

Minor Code: 0x00F4
(crypto disabled)

During secure boot, After PL loading is done then the PLM checks for the crypto bit
if the bit is programmed then PLM will throw an error otherwise it boots further
The above error is applicable to the applications running on A72/R5/microblaze

Try PDI programming on the different board where the crypto engines are enabled

To check whether the crypto is enabled or not
xsdb: mrd 0xF1250018
and check if the 29th bit is
0 - crypto is enabled
1 - crypto is disabled
