Log in U-Boot through NOR Flash not working

I have tried the instructions for the NOR U-Boot at:
and a description someone gave on IRC: "hold in aux, then hold in power while still holding in aux until it boots"
Nothing happens when I try this.

The AUX button works okay in other contexts.
I can get to the NAND menu and boot the device up, too.

On IRC I got the impression that only some devices (or people) have this problem.

Could you please

and either attach the file to this bug report or mail it to
werner@… ?

Thanks !

Argh. I was afraid it would look like that :-(

This could be either a defective NOR chip or the programming at the
factory didn't happen for some reason.

You mentioned in private mail that you'll soon have the opportunity
to reflash the NOR. Can you please report if this was successful ?

Let's hope it's "only" a production process issue ...

Reflashing the NOR using a v3 debug board worked. As far as this device is concerned, the problem appears to be solved.

comment:5 Changed 11 years ago by werner

An update: we found a flaw in the production testing process that can let
devices with an incorrect NOR content pass. Don't know yet what caused the
NOR to be incorrect in the first place, though.
