Package: raspi-firmware Version: 1.20200601-3 Severity: important Dear Maintainer,
I am using 32-bit armhf executables on linux-image-arm64 kernel running on Raspberry Pi 4B, because * armhf executables use smaller memory and storage than arm64, * 32-bit arm kernels are unsupported on arm64bit CPUs, as told at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=971059#12 by the kernel package maintainer Ben Hutchings. /etc/kernel/postinst.d/z50-raspi-firmware has to understand that it is running on a 64bit kernel. But it fails to do so. Because it use: arch=$(dpkg --print-architecture) if [ "arm64" = "$arch" ]; then dtb_path="/usr/lib/linux-image-${latest_kernel#/boot/vmlinuz-}/broadcom" else # there is no vendor subdirectory for armhf dtb_path="/usr/lib/linux-image-${latest_kernel#/boot/vmlinuz-}" fi Since all binaries are 32-bit, dpkg --print-architecture prints armhf, while the kernel is linux-image-arm64. I think "uname -m" should be used in place of "dpkg --print-architecture".
