Begin forwarded message: Date: April 16, 2008 9:55:30 PM GMT+08:00 Subject: Re: [gta02] u-boot boot menu regression ?
Just a thought, maybe you can change this to act like that if there was
no valid environment in NAND, that might meet the request and be a
reasonable behaviour for users too, without having special modified
builds for factory.
Like this ? I kind of doubt this solves Miles' problem, though.
All you get is the boot menu that offers you "Boot", which of
course doesn't work, since you don't have the partition table.
ObWolfgang: the reason why I'm not sending this patch to the
public list is that it's probably useless and I don't even
think I understand where in the factory the problem is. In
case that patch should turn out to be useful, I'll be happy
to repost it ;-)
Cheers, Werner
