Steps for Enabling Power off Suspend feature

Create HDF with GPO2 polarity to High

1. Source petalinux settings.

   Code Block
   theme Midnight
   source <plnx-settings.sh>

   
   

2. Create petalinux project using below command.

   Code Block
   theme Midnight
   petalinux-create -t project -s <petalinux BSP path>

   
   

3. Start Xilinx Vivado 2018.1
4. Open existing petalinux project from Vivado. (Located at <plnx-proj-root-dir>/hardware/xilinx-zcu102-2018.1/xilinx-zcu102-2018.1.xpr)
5. Open block design, customize block design using double click on "Zynq UltraScale+ MPSoC" block. (or right click and then click on "Customize Block" option)
6. On the "Page Navigator" bar, click on I/O configuration.
7. Go to Low Speed -> IO Peripherals -> PMU -> GPO2. Default polarity of GPO2 is low. Change GPO2 polarity to high as per below snapshot and click "OK".
   
8. In the Flow Navigator → PROGRAM and DEBUG, click on "Generate Bitstream" option.
9. Export HDF file
   • Go to File → Export → Export Hardware
   • Check "Include bitstream in HDF" option. Set export path if required or keep it default(<Local to Project>). Click "OK"
   • In case of default path, HDF file will be generated at <workspace>/<project_name>/<project_name>.sdk/<block_name>.hdf.
     
     

Build images using Petalinux

1. Source petalinux settings:

   Code Block
   theme Midnight
   source <plnx-settings.sh>

   
   

2. Create petalinux project using below command:

   Code Block
   theme Midnight
   petalinux-create -t project -s <petalinux BSP path>

   
   

3. Configure petalinux using custom HDF (generated in previuos steps) using below command:

   Code Block
   theme Midnight
   petalinux-config --get-hw-description=<HDF file root directory path> --oldconfig

   
   

4. Enable ZynqMP firmware debugfs config in Linux kernel (ZYNQMP_FIRMWARE_DEBUG) using below steps:
   • Run "petalinux-config -c kernel" command.
   • Go to Firmware Drivers -> Zynq MPSoC Firmware Drivers and enable Xilinx Zynq MPSoC firmware debug APIs.
   • Save configuration and exit from that.
5. Enable POS related build flag in FSBL (ENABLE_POS) using below steps:
   • Create project-spec/meta-user/recipes-bsp/fsbl/fsbl_%.bbappend file if not present.

   • Append below line in that file.

     Code Block
     theme Midnight
     YAML_COMPILER_FLAGS_append = " -DENABLE_POS"

     
     

6. Enable POS related build flag in PMUFW (ENABLE_POS) using below steps:
   • Create project-spec/meta-user/recipes-bsp/pmu/pmu-firmware_%.bbappend file if not present.

   • Append below line in that file.

     Code Block
     theme Midnight
     YAML_COMPILER_FLAGS_append = " -DENABLE_POS"

     
     

7. Build petalinux using below command:

   Code Block
   theme Midnight
   petalinux-build

   
   

8. Run below command inside petalinux root directory to generate BOOT.BIN:

   Code Block
   theme Midnight
   petalinux-package --boot --fsbl images/linux/zynqmp_fsbl.elf --u-boot images/linux/u-boot.elf --pmufw images/linux/pmufw.elf --atf images/linux/bl31.elf --fpga

   
   

9. Built images (BOOT.BIN and image.ub) are present at <plnx_root_dir>/images/linux/

Sample Images:

• HDF generated from petalinux 2018.2 reference project.
  zcu102_wrapper.hdf
• Below is the images which is generated from petalinux 2018.2 using above HDF
  1. ATF bl31.elf
  2. PMUFW pmufw.elf
  3. U-Boot u-boot.elf
  4. Bitstream system.bit
  5. FSBL zynqmp_fsbl.elf
  6. BOOT.BIN boot.bin
  7. image.ub image.ub
