When I tried to apply the fix by switching to a different text terminal by pressing ctrl+alt+f5, the terminal would become unresponsive to keyboard input after a few dozen seconds. Can somebody confirm?
If fixing this via another tty does not work and because there is no graphics support in u-boot so that you could choose the single user mode rescue shell in the boot menu, you have the following options:
- connect to serial via uart and log into your system that way
- if you have an ssh server configured, log in via ssh after booting
- flash a rescue system to sd-card, boot that and mount and chroot your system on eMMC/NVMe from the rescue system
To make the last option easier, I started writing a new script. I put an initial version here:
I welcome tests and feedback for this script. Thank you!
