Embedded SW Support
There are many system software components needed in order to design and deploy a fully functioning system based on a Xilinx Adaptive SoC, Adaptive SoC or FPGA. This software is a combination of components developed and delivered by Xilinx as well as software that is open source and freely available and the support for such software will vary depending on the software in question. In general, Xilinx will support the latest 2 major versions (currently 2024.x and 2023.x) of the system software and tools that it delivers as part of PetaLinux and Xilinx SDK. Note that "support" means that we will assist in resolving issues via the forums or service requests (if eligible) but does not guarantee any patches or backporting of patches which are handled on a case-by-case basis. For the publicly available open-source software, support should first be obtained via the forum or mailing list identified below in the self-support column. Assisted support via service request is provided on an exception basis as outlined in the table below. All other content on the Wiki is provided "as is" and support is available via the Embedded Forums.

SDK
| The Xilinx SDK is a collection of tools used for doing Embedded SW Development, Debug, Performance Optimization, and Deployment. It includes facilities for generating project specific BSPs, libraries, and example code. Additionally, XSDB is the debug tool incorporated in the Xilinx Software Command LIne Tool (XSCT) and in the XSDK GUI. | Embedded SW on Github | Embedded Development Tools Forum |

PMU FW | The Platform Management Unit (PMU) is critical to the proper operation of a Zynq US+ MPSoC-based solution. Xilinx provides source which builds binaries tested for such proper system operation. Though customers are enabled with sources and tools to rebuild PMU firmware, customers should carefully consider modification of any software due to potential impact on proper system operations. For those customers who choose to modify PMU Firmware, Xilinx provides support only to enable customers to build and debug such code. Due to the deeply embedded nature of this code, Xilinx is unable provide support which ensures customers of proper system operation subsequent to modification. Only rarely, and with consideration does Xilinx expect customers to modify PMU-firmware. For those customers who do choose to modify the code, support by Xilinx will be limited to use of Xilinx tools to modify and rebuild the sources, and to those functions which are included in Xilinx releases. | Embedded SW on Github | Embedded Linux Forum |

Power Management | This Power Management Framework handles several use cases scenarios. For example, Linux provides basic power management capabilities such as idle, hotplug, suspend, resume, and wakeup. The kernel relies on the underlining APIs to execute power management decisions, but most RTOS's do not have this capability. Therefore they rely on user implementation, which is made easier with use of the Power Management Framework and the XilPM library. | Embedded SW on Github | Embedded Linux Forum |

ATF | Properly developed and tested ARM Trusted Firmware is fundamental to recommended/supported operation of the APU. The binaries, built with source code provided by Xilinx, are supported and tested for Xilinx-enabled use cases and features including CSU access, AMP and power management support. Only rarely, and with consideration does Xilinx expect customers to modify ATF. For those customers who do choose to modify the code, support by Xilinx will be limited to use of Xilinx tools to modify and rebuild the sources, and to those functions which are included in Xilinx releases. | ATF on Github | Embedded Linux Forum |

U-Boot, Drivers and Flash Parts | Xilinx U-Boot is an open source project based on http://git.denx.de, that is used as a second stage boot loader in order to boot Linux OS on Xilinx HW Platforms including Microblaze, Zynq-7000 and Zynq Ultrascale+ devices. Along with boot loader functionality it offers some essential device drivers like UART, GPIO, I2C etc. for Xilinx HW platforms. It also lists the latest Flash devices tested, and up streams Xilinx patches. | U-Boot on Github | U-Boot Wiki Flash Parts: | Embedded Linux Forum |

PetaLinux Tools & PetaLinux BSPs | PetaLinux is a Xilinx Linux development tool and contains everything necessary to create, configure, build, test, package and deploy Embedded Linux systems on a Xilinx Hardware and QEMU Emulation Platform. It provides board support packages for Xilinx and third-party boards with prebuilt images. It uses the Yocto build system under the hood. | PetaLinux Product Page | Embedded Linux Forum |
|
| |
Yocto | Xilinx uses Yocto eSDK build system within our PetaLinux product which is the exclusive extent to which we test Yocto. Xilinx does provide Yocto recipes for all key components but we do not test these outside of the PetaLinux tools context. It is incumbent on our customers to address any issues between their own in-house Yocto build system and the Yocto recipes provided by Xilinx. | meta-xilinx on Github meta-petalinux on Github meta-openembedded on Github meta-linaro on Github meta-virtualization on Github meta-openamp on Github meta-xilinx-tools on Github meta-qt5 on Github | For reporting bugs/patchs, please use the appropriate mailing list: For anything else, post to: Embedded Linux Forum |

FreeRTOS | Xilinx XSDK includes a tested port of FreeRTOS for Xilinx silicon. This includes critical drivers needed to ensure basic multi-threaded support of FreeRTOS on Xilinx products. Xilinx bare-metal drivers can be used within a single-threaded context on FreeRTOS. It is beyond scope of Xilinx to provide support to customers who wish to use the bare-metal drivers in a multi-threaded application context. | Embedded SW on Github | FreeRTOS Forum |
