I used the rootfs (musl, aarch64) and set up the filesystems on a USB flash drive, copied the files and then chrooted and followed the website guide. I did however have problems with booting right after GRUB loads the initramfs. I got the following errors:
EFI stub: Booting Linux Kernel... EFI stub: ERROR: FIRMWARE BUG: kernel image not aligned on 64k boundary EFI stub: Using DTB from configuration table EFI stub: Exiting boot services...
The next screen showing up gives the following error which appearantly has to do with the GPU:
[ 5.015806] lima d00c0000.gpu: error -EMODEV: dev_pm_opp_set_regulators: no regulator (mali) found.
After this the computer reboots. Can any of you help me out with this? I would really appreciate it. I have flashed the La Frite with the 2021 U-boot image.
