Eddie, I spoke with you on the phone about problems creating a SD card to boot a ts-7400 board. you asked me to send you the information from what I did. I used fdisk and created three partitions on a debian pc. I then create a linux file system from the debian pc. I can mount that file system to the debian pc. but I can not mount it to the 7400 board. I am sending you logs for both the debian pc and the 7400 board. Eddie Dawydiuk <> wrote:

e2fsck: Bad magic number in super-block while trying to open /dev/sda
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
