Howto install archlinuxarm raspberrypi5
download image
download archlinux-arm-aarch64 image:
wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-aarch64-latest.tar.gz
chroot with qemu
use qemu-user-static to interpret the arm instructions in the chroot:
pacman -Sy qemu-user-static --noconfirm
copy the qemu-aarch64-static binary to the chroot:
cp /usr/bin/qemu-aarch64-static /mnt/temp/usr/bin
register the qemu-aarch64-static as an arm interpreter in the kernel:
echo ':aarch64:M::\x7fELF\x02\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x02\x00\xb7:\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xff\xfe\xff\xff:/usr/bin/qemu-aarch64-static:' > /proc/sys/fs/binfmt_misc/register
script to mount image:
#!/bin/bash
if [ ! -d /mnt/temp ];
then
mkdir /mnt/temp
fi
kpartx -va $1 1> /tmp/part-names.txt
PART2=$(cat /tmp/part-names.txt | awk '{print $3}' | grep p2$)
PART1=$(cat /tmp/part-names.txt | awk '{print $3}' | grep p1$)
sleep 1
mount /dev/mapper/$PART2 /mnt/temp
mount /dev/mapper/$PART1 /mnt/temp/boot/
sleep 1
mount -o bind /dev /mnt/temp/dev
mount -o bind /dev/pts /mnt/temp/dev/pts
mount -o bind /proc /mnt/temp/proc
mount -o bind /sys /mnt/temp/sys
rm /tmp/part-names.txt
if [[ $1 == *[32]* ]]; then
mount -o bind ./pkg32 /mnt/temp/var/cache/pacman/pkg
fi
if [[ $1 == *[64]* ]]; then
mount -o bind ./pkg64 /mnt/temp/var/cache/pacman/pkg
fi
enter chroot using arch-chroot:
arch-chroot /mnt/temp
