Jonathan,
Thanks much as your last two posts help tremendously. Our biggest concern with using NAND for both the u-boot images
(and our own) was having a block go bad. We did not want our units to end up dying in the field bec... Anonymous

JC 01:29 PM Software Development: RE: NAND memory map question

So looking in the following file you can see that there is support in the MLO for having a redundant environment partition, although we don't use it. It would probably not be difficult for someone to also add a redundant u-boot partitio... Jonathan Cormier

John,
Thanks for the clarification, I was looking in the kernel repository not the U-boot one.
I am not too familiar with the u-boot mlo implementation. I'm not sure what it would take to have the MLO support two locations for the... Jonathan Cormier

Hi,
We are currently running the AM3352 cpu module and was hoping for some clarification on where everything sits in
NAND as certain comments in files don't seem to line up with TI's wiki pages or the mityarm335x.h file
