i.mx6ulevk nand too small?

[belginstirbu]

Hello! I've followed the steps How-To use NAND boot on i.MX6UL EVK board but this is the result after booting with mfgtools2. I am certain the nand flash is big enough. What am I doing wrong?

I've fixed the issue by applying these modifications

Commit: 2580a2a7e719ee6bf20d8d6bcbe0c01a74cd2d54 - uboot (git) - OSDN

and then recompiling u-boot like in the instructions in my original post.

By the way, to recompile you need to run `make' a little differently, like this

cd fsl-release-bsp/build/tmp/work/imx6ulevk-poky-linux-gnueabi/u-boot-imx/2015.04-r0/git

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
