Extracting a Petalinux BSP

A Petalinux BSP is simply a gzipped tar file that contains a preconfigured Petalinux project. A BSP may (and the Xilinx BSPs do) also contain precompiled copies of build outputs that you would get from running petalinux-build in that project.

$ tar -xzf xilinx-zcu102-2021.2-final.bsp
$ ls
xilinx-zcu102-2021.2

$ cd xilinx-zcu102-2021.2
$ ls

$ ls pre-built/linux/images
