So, when building an arm64 linux package using Debian's packaging, it builds a package where /boot/vmlinuz-VERSION is uncompressed, and bootloaders such as u-boot can boot it with booti. But when building a mainline kernel with "make bindeb-pkg" it produces a package where /boot/vmlinuz-VERSION is compressed with gzip, and u-boot's booti fails to boot it. Simply uncompressing the /boot/vmlinuz-VERSION then allows u-boot's booti command to work properly. I seem to recall a similar issue with grub not booting the compressed image, but it's been a while since I've tried. Debian's linux packaging seems to manually specify the image type in debian/config/arm64/defines: image-file: arch/arm64/boot/Image Upstream defaults to Image.gz in arch/arm64/Makefile: KBUILD_IMAGE := Image.gz Are there platforms on arm64 that use Image.gz? Should upstream default to "Image" instead, or should upstream's bindeb-pkg target default arm64 builds to use KBUILD_IMAGE=Image, to be consistant with Debian's linux packages? live well, vagrant
