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 require a Linux kernel, a rootfs with integrated Xilinx Runtime, and a sysroot to cross-compile the host application. You can create your own embedded platforms, or download pre-built platforms.

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.

You can build your own platform software, or use a pre-built software common image. To download a pre-built common image, 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 -d gives 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>/cortexa72-cortexa53-xilinx-linux, which is generated when running sdk.sh.
