Official Debian support

[sepp]

Finally I figured it out: Debian bullseye stock on nvme:

Here is what I did:

Prerequisite: bulleye sd card created with https://d-i.debian.org/daily-images/arm6...rd-images/

Installed this u-boot to emmc: the modified u-boot images provided by forum user pcm720
be sure to have not boot partition on emmc

create an ext4 and a swap partition on nvme0n1
ext4 nvme0n1p1
swap nvme0n1p2

debootstrap into nvme0n1p1 following this https://gist.github.com/varqox/42e213b6b2dde2b636ef
(instead of debootstrap the Debian install can also be use but then a serial interface is needed - for debootstrap any Distro booted from SD card works)

create symlinks for vmlinuz-5.10.0-7-arm64 (vmlinuz) and initrd.img-5.10.0-7-arm64 (initrd.img)
cp dtb, dtb-5.10.0-7-arm64 and dtbs folders recursive from boot on debian sd card

to have the following boot folder on nvme0n1p1
root@Pine64:/# ls -ltra boot

you cannot just copy the boot.scr from debian. you have to strip the 72 long u-boot header like so https://wiki.ubuntu.com/ARM/EditBootscr to get a boot.cmd

insert a line into boot.cmd (the one I use is attached)

setenv bootargs  ${bootargs} quiet
(this one) setenv bootargs root=/dev/nvme0n1p1 rootwait ${bootargs}

if test -z "${fk_kvers}"; then

and
mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr

issues remaining:
nvme not detected sporadically though rootwait
wakening from suspend
sound: es8316.c in linux-source is outdated. Upstream contains the necessary patch by Tobias Schramm. so this will come (and I want to stick to stock as this is "Official Debian support")
