Hello,

I am using the latest u-boot (1.1.4) code and it doesn't have 2Gbits (256 MBytes) NAND flash support.

I appreciate if some one can point me in the right direction to use the 2Gbits NAND flash from U-boot. (Chip: Micron MT29F2Gxxxxx)

Maybe you should check with Micron if this is a viable memory chip. MT29F2G16AABWP is dead according to my sources and there are no second sources available.

I want to boot the linux kernel from the NAND flash.

Thanks, Hebbar.

Best Regards Ulf Samuelsson

This statement is not correct:

Please make sure that you use the "new" U-Boot NAND driver (driver/nand/*) and _not_ the "old" legacy driver. This could be your problem.
