https://git.yoctoproject.org/poky/plain/scripts/lib/wic/plugins/source/bootimg-efi.py objcopy_cmd = "%s-objcopy" % target_sys objcopy_cmd += " --enable-deterministic-archives" objcopy_cmd += " --preserve-dates" objcopy_cmd += " --add-section .osrel=%s/usr/lib/os-release" % staging_dir_host objcopy_cmd += " --change-section-vma .osrel=0x20000" objcopy_cmd += " --add-section .cmdline=%s" % cmdline.name objcopy_cmd += " --change-section-vma .cmdline=0x30000" objcopy_cmd += dtb_params objcopy_cmd += " --add-section .linux=%s/%s" % (staging_kernel_dir, kernel) objcopy_cmd += " --change-section-vma .linux=0x2000000" objcopy_cmd += " --add-section .initrd=%s" % initrd.name objcopy_cmd += " --change-section-vma .initrd=0x3000000" objcopy_cmd += " %s %s/EFI/Linux/linux.efi" % (efi_stub, hdddir) Yeah that's a bug, and it needs to be fixed, those sizes can't be hard-coded like that, as soon as you build a slightly different stub it's going to break.
