I recently upgraded to OpenWrt 22.03.5, had to do a fresh install and tried configuring extroot. It seems I have messed up with setting up fstab, since when I run block info, I see only the following:
/dev/mtdblock5: UUID="052e869a-5e925913-fd01a3bc-856ad302" VERSION="4.0" TYPE="squashfs" /dev/sda1: UUID="28854925-6e5f-4ec0-b728-b07915960d83" VERSION="1.0" TYPE="ext4"
While it was listed before I started the operation, now /dev/mtdblock6 is no longer present. /dev/sda1 is the memory stick I had used as extroot storage.
I tried to go for a reset from the web interface, but after selecting "Perform select" and a few seconds I just get returned to the home page. How deep trouble am I in and how can I recover from this situation?
