Need help - Goflex home - uboot corrupted - errors wrting flash (3 replies)

I was moving away from arch to debian on my goflex home and debootstrap gave me incompatible hardware error. I chaged the arch number to dockstar and that action or something corrupted my environment.

I tried to update uboot with Jeff's script and it failed.

I also followed Bodhi's thread for manually writing the uboot here.

Here is my output. Everytime I read uboot I am getting different data.

I am currently in the rescue mode. Not sure how to proceed. It looks like mtd0 has bad flash. Can I use chained uboot from mtd3? How does one do it?

BTW the serial port on this device has stopped working too. I am using the same serial cable that I used to install rescue and uboot on this device previously. Is this connected to the corrupted environment?


Thanks....
