Hi @yuezhiran, I believe it's valid for this function to return 0. The bl1_plat_handle_post_image_load function is overridable by the platform, but we do not provide a mechanism for the platform to communicate the "acceptable" image IDs to the caller. We cannot therefore return an error if we receive an image ID that has no post-load process, because it may be called for any image (the FWU process does this here).

I can only assume GCC <11 simply didn't have this warning, but it looks legitimate.

Hi all, I suggest we move this discussion back to the mailing list so we can track the progression a bit more easily.
