Pogoplug v4 restore

Hi,

I am trying to restore a pogoplug v4 device. Managed to get uboot working with UART but no Linux.

Am not sure what I am missing. Tried everything on the forums but I could not find a page where it gives the steps for going from uboot prompt to Linux.

Can you let me know the next steps please.


Thanks.

Mark,

1. Create a Debian rootfs on a single Ext3 USB thumb drive using another Linux box. See the latest rootfs here:
http://forum.doozan.com/read.php?2,12096

You can use either rootfs 3.16 or 3.18.5, does not matter. But 3.16 is simpler to create.

2. Plug in the USB drive and boot at u-boot prompt
> boot

This error indicates that your UBS drive does not have the correct partition format for booting. Which u-boot is on your Pogo V4? which u-boot did you use for UART booting? I'm guessing you're trying to boot with Ext4 rootfs, and this is possible with the new u-boot, but not with any other u-boot that you might have before, including stock.

Please post the entire serial boot log.

Bodhi,

You are correct. I did manage to fix the issue. I did not have a Linux machine so I was using a windows utility for the USB. Setting up a Linux machine and setting up USB stick as ext2 fs from there fixed the problem.

Thanks again for your help.
