AMD hosts all source download tar files for each release at By default, PetaLinux points to pre-mirrors using petalinux-config command.

If any component is rebuilt from scratch, BitBake, or devtool searches for its source in pre-mirrors and downloads the mirror URL. Later, it searches in SRC_URI of recipes for downloading the source of that component. If you configure any value through petalinux-config > yocto settings > premirrors, it first searches in the configured pre-mirrors,, and finally in the SRC_URI in recipes.

You can add more mirrors by adding SOURCE_MIRROR_URL += file:///home/you/your-download-dir/ in <plnx-proj-root>/project-spec/meta-user/conf/petalinuxbsp.conf.
