Thanks Seife! I gave this a try and now I am in a boot loop: ``` Booting /efi\boot\bootaa64.efi Please press 't' to show the boot menu on this console error: ../../grub-core/video/video.c:761:no suitable video mode found. error: ../../grub-core/commands/boot.c:196:you need to load the kernel first. resetting ... ``` Not sure why suddenly it does no longer show the grub2 console but rather asks for pressing 't'. I need to investigate what I did wrong :-) But at least it seems like the automatic reboot is working. Unfortunately it errors out after some loops: ``` U-Boot SPL 2022.10 (Oct 04 2022 - 00:00:00 +0000) DRAM: 2048 MiB Trying to boot from MMC1 spl: mmc init failed with error: -110 SPL: failed to boot from all boot devices ### ERROR ### Please RESET the board ### ``` But that might be the other error, the one where u-boot does not boot.. Kind Regards, Johannes
