No nevermind, thats not correct. You do have a 256MB nand module. So the first u-boot should be correct. Jonathan Cormier

Woops hangon didn't notice that you had a 3352 module. They have a larger nand and require a special u-boot build. Jonathan Cormier

What version of U-boot are you using? If you can include the full bootlog that would be helpful.
