I have installed debian on my SheevaPlug. After a few days of working it fails and reboot gives me following:

UBIFS: recovery needed
Error reading superblock on volume 'ubi:rootfs'!

Wrong Image Format for bootm command

More likely problem is related to file system overflow caused by my process that writes too much debug output via syslog.

Once I have recovered by
- booting with USB stick,
- mounting Flash partition
- removing log files from /mount/var/log/messages
After that I can boot again from Flash.

But now board is not at my hands and all I can do is to ask customer to enter a commands via RS232 terminal.

My questions are:
  • Is where any wayt to recover it with uboot commands only?
  • What actually happens? I mean what is problematic in u-boot output above and where actually the problem starts?

Thanks a lot.
