Reflashing NAND from uBoot?

[mycorunner]

I bricked my pogoplug E02 but have serial access. I realize there are similar threads posted but I am not sure if the problem I'm having is the same, so I started a new thread.

I had ALARM running on a pogoplug E02 and I changed the arc number from 2098. I didn't really know what I was doing (trying to get the LEDs to work correctly) and sure enough, it wouldn't boot, with or without the usb flash drive with ALARM. I had previously installed Jeff Doozan's rescue system as well. Here is what I get when I boot:

Code: Select all

I updated the uBoot following this guide (http://forum.doozan.com/read.php?3,6965) and from what I can tell it is working, but I can't boot into the device. I don't have a USB set up to test booting from USB (the pogoplug was my only linux computer...)

Is there a way I can flash either the Rescue System or the original firmware via serial and tftp the way I did with uBoot, or will I need to get a system up and running from USB to do that?

Also, here is the output of 'printenv' if I interrupt the boot process:

Hopefully that helps...

On E02 arcNumber=3542
For some reason it doesn't recognise your USB flash/hard drive as a storage device...
