recover SBC3

I have an SBC3 that has stopped responding, I can't ping it, detect it with the phidgets software or anything. I have a number of programs running on it that I really don't want to lose. Is there any other way to access what is stored on it?

You can attempt to recover files from the recovery system, but this may fail if the main partition has major issues - as it may it it's not booting.

I tried the recovery : ubiattach /dev/ubi_ctrl -m 6
i get get this error message: ubiattach: error!: cannot attach mtd6
error 22 (Invalid argument). I'm guessing it is not finding my file system. I really need to recover these files

Hi,
I have looked into this, and that command is for SBC2. For SBC3, you want:
ubiattach /dev/ubi_ctrl -m 7

After mount failure, can you run dmesg and post UBI related output?
