Yocto e-SDK contains minimal shared state (sstate) cache. Xilinx® hosts the full petalinux-image-minimal sstate cache at https://petalinux.xilinx.com/sswreleases/rel-v2022.

During petalinux-build, BitBake searches for the sstate cache in https://petalinux.xilinx.com/sswreleases/rel-v2022. If it fails to find the sstate cache, BitBake will build it from scratch. sstate is signature locked.

For a .bbappend file which you create for any root file system component, you must add SIGGEN_UNLOCKED_RECIPES += "<recipe-name>" (for example, example, SIGGEN_UNLOCKED_RECIPES += "u-boot-xlnx" in <plnx-proj-root>/project-spec/meta_user/conf/petalinuxbsp.conf.
