Suse on Toshiba AC100 (paz00) not starting

[wurzel]

Hello,

I tried to install Suse on my Toshiba AC 100.

I installed the boot loader from this guide: Migrate to U-Boot — Toshiba AC100 wiki
To test the installation, I booted with out sd card. It starts to u-boot prompt. So u-boot seems to work as intended.

I prepared the sd card using

xzcat openSUSE-Tumbleweed-ARM-XFCE-paz00.armv7l-2024.01.16-Snapshot20240310.raw.xz | dd bs=4M of=/dev/sdb iflag=fullblock oflag=direct status=progress; sync

ths lsblk output is

sdb      8:16   1    59G  0 disk
├─sdb1   8:17   1    16M  0 part
├─sdb2   8:18   1   500M  0 part
└─sdb3   8:19   1   3,7G  0 part

When I insert the sd card, grub starts, but gives me only a prompt and gibberish if I press any key. https://www.youtube.com/watch?v=NRo71eO79cA

I also tried with openSUSE-Leap-15.3-ARM-XFCE-paz00.armv7l.raw.xz. Same result except different grub version.

My guess there is something wrong with grub. I need help

Update:

I re-installed the bootloader but replaced u-boot-dtb-tegra.bin with u-boot-dtb-tegra20-paz00.bin from https://4pda.to/forum/index.php?showtopic=367318&st=2060

I also reverted to a previous bct with OdmData = 0x800c0075; instead of OdmData = 0x0000c0000;

Suse leap is booting now. Lokks like the problem is solved.
