Embedded platforms are available to download from the Vitis Embedded Platforms download page for use in the Vitis unified software platform. For the Vitis embedded software development flow, you can use embedded platforms with Linux, standalone/bare metal, or RTOS domains. To support the Vitis application acceleration development flow, embedded platforms must run Linux, with XRT integrated into the rootfs. A complete list of the supported platforms can be found on the downloads page.

To install a platform, download the zip file and extract it into /opt/xilinx/platforms, or extract it into a separate location and add that location to the PLATFORM_REPO_PATHS environment variable.

Embedded platforms require a sysroot to cross-compile the host application for the Vitis application acceleration flow. Look for the Common images for Embedded Vitis platforms block on the downloads page, and download and extract the common image for your platform architecture.

Running sdk.sh extracts and installs the sysroot. The option -dgives you the option to choose where to install the sysroot. This package also provides a pre-compiled kernel image and rootfs.

You can add the sysroot to a Makefile for your command line project, or the Vitis IDE will prompt you to add it to your application project. For example, in your Makefile point <SYSROOT> to /<install_path>/aarch64-xilinx-linux, which is generated when running sdk.sh.
