radsfaninlv,

A couple things to try:

1. Your uBoot envs look good, except that the machid is still set to dd6, while arcNumber is 2097. Without USB attached, try setting it again to 831 in serial console:

> setenv machid 831
> boot

see if it will boot into rescue system.

2. Download the latest rootfs (link in my signature) and put it on a USB thumb drive. In serial console, set arcNumber to 3542, and machid to dd6 and boot:

> setenv arcNumber 3542
> setenv machid dd6
> boot

see if it boots into Debian

I figured out how to get a command prompt. It helps to fully read the output.

I changed the machine id to 831 and the arcNumber to 2097 but it still doen't boot.

output of printenv:

It looks like I have the wrong machine ID but I am not sure how to send a command via putty to fix it. I have tried googling it but no joy yet. When I plug it in to a router I don't get a IP address. Thanks for your help bohdi.

radsfaninlv,

You do need a serial cable, if netconsole was not set up. Boot with serial console and look at uBoot envs, you might have typos in one of those uBoot envs, if you have been changing them. If you can't spot the error, post the output of uBoot command printenv.

I have messed up my pogoplug E02 so badly that it won't boot in to the rescue system or from a usb stick. To fix this am I going to need a serial cable? If so, do I just reinstall the rescue system?

Thanks.
