Note: The Arm AArch64 architecture is common between the APUs used for Zynq UltraScale+ MPSoC the Versal devices. The existing architectural reference nomenclature
"ZynqMP" found the
Linux source also applies to Versal devices.
The Linux OS supports the Versal device. AMD provides open source drivers for all peripherals in the PS, and key peripherals in the PL. The following figure illustrates the full software stack in the APU, including Linux and an optional hypervisor.
Figure 1. Linux Software Development Stack
AMD offers two tools to build and deploy custom Linux distributions for Versal devices: PetaLinux tools and the open source collaboration project, Yocto project. For more information, refer to the Linux Wiki.
- Yocto Project
- The Yocto Project can be used to highly customize embedded Linux for their boards. For those interested in the Yocto Project, the Wiki has several articles and information pertaining Yocto for building Linux on AMD devices. The Yocto page on the Wiki is a great place to start. Yocto board support packages are also available from the main Yocto tree.
- PetaLinux Tools
- The PetaLinux tools offer a simplified commands set to quickly build embedded Linux. The tools include a branch of the Linux source tree, U-Boot as well as Yocto-based tools to make it easy to build complete Linux images, including the kernel, the root file system, device tree, and applications for AMD devices. The PetaLinux tools work with the all the same open source Linux components described immediately below. More information about using PetaLinux to build custom distributions can be found on the PetaLinux Tools and PetaLinux Yocto Tips pages.
You can leverage the Linux software stack for the Versal device in multiple ways.
- Open Source Linux and U-Boot
- AMD offers release-specific prebuilt images for the VMK180 and VCK190 evaluation kits that can be found on the Versal Boards, Kits, and Modules page. The Linux Kernel sources including drivers, board configurations, and U-Boot updates for Versal devices are available from the official Linux kernel for AMD, as well as, from the main Linux kernel and U-Boot repositories. For more information, refer to the Release Notes for Open Source Components .
- Commercial Linux Distributions
- Along with open source Linux offerings, AMD works with several third-parties to offer other Linux solutions. Some commercial distributions also include support for the Versal devices, and they include advanced tools for Linux configuration, optimization, and debug.
