Mobian won't boot after ton of updates

[bartgrefte]

From JumpDrive, you may also be able to check system logs on the PineTab's eMMC to look for errors. (Which may or may not show anything, depending on how far the device is getting in the boot process..)

I improvised a debug-cable with a computerspeaker-cable and Adafruit FTDI Friend. From what I can tell from the output, Mobian seems to boot (at least partially), it ends with

Code:

Maybe worth noting: The keyboard backlight does not switch on as usual, nor does the key-combo work, maybe that gives an idea about where in the boot process it got stuck? Also not seeing it appear on the network.

edit:
After going through the output again:
U-Boot menu
1: Mobian GNU/Linux 6.1-sunxi64
2: Mobian GNU/Linux 5.15-sunxi64
Just tried option 2, that works
