I am trying to follow this manual (https://earthly.dev/blog/cross-compiling-raspberry-pi/) to set up crosscompiling for RPi zero 2w running raspbian bullseye.
So far I have failed with any crosscompile setup for Rpi, however I have found out I do need to write a new driver - and I refuse to attempt that on the Zero.
However my Zero is obviously running on arm64 and not armhf, so I get error output
$ mk-sbuild --arch=$ARCH $RELEASE --debootstrap-mirror=http://archive.debian.org/debian/ --name=rpi-$RELEASE --debootstrap-mirror=http://archive.raspbian.org/raspbian/ --name=rpi-$RELEASE
/usr/sbin/qemu-debootstrap
W: qemu-debootstrap is deprecated. Please use regular debootstrap directly

when running the suggested command
mk-sbuild --arch=$ARCH $RELEASE \
--debootstrap-mirror=http://archive.raspbian.org/raspbian/ \
--name=rpi-$RELEASE
The output of my target RPi zero, running the original raspbian:
$ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 11 (bullseye)"
NAME="Debian GNU/Linux"
VERSION_ID="11"
VERSION="11 (bullseye)"
VERSION_CODENAME=bullseye
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"
$ dpkg --print-architecture
arm64
so in the above command $ARCH=arm64 and $RELEASE=bullseye.
There is only armhf files http://archive.raspbian.org/raspbian/dists/
I do not think I should use those... where to get the arm64 ones? Or can anyone suggest another approach to build an SDK to develop drivers?
