I've been looking at the scripts of the installer and openOCD. I see that the installer uses openOCD to write images to the NAND in the plug. I also see that openOCD has the ability to read NAND and save it as a file.
I think a new utility that reads nand images to a file would be a very useful addition to the toolbox. This could provide a backup of the plug as received and would enable the device to be restored to its' "as delivered" state. This would be an excellent safety net for those of us looking to learn by our mistakes!
I could probably eventually make this utility but maybe someone (Rabeeh?) could do it a lot quicker than me.
