i.MX28evk u-boot stops booting the kernel

Hello community,

I try to boot the i.MX28evk with u-boot, this is what I get

U-Boot 2013.01-00161-g6e787b7-dirty (Feb 07 2013 - 13:59:57)

CPU: Freescale i.MX28 rev1.2 at 454 MHz

BOOT: SSP SD/MMC #0, 3V3

I2C: ready

DRAM: 128 MiB

MMC: MXS MMC: 0

## Booting kernel from Legacy Image at 42000000 ...

Image Name: Linux-2.6.35.3-571-gcca29a0

Created: 2012-12-05 9:57:50 UTC

Image Type: ARM Linux Kernel Image (uncompressed)

Data Size: 2562120 Bytes = 2.4 MiB

Load Address: 40008000

Entry Point: 40008000

Verifying Checksum ... OK

Loading Kernel Image ... OK

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

This is what I have done:

build u-boot 2013.01 from denx git with mx28evk_config
build kernel 2.6.35 and rootfs with LTIB
created MMC Card

/dev/sdb1 2048 4095 1024 53 OnTrack DM6 Aux3

/dev/sdb2 4096 24575 10240 e W95 FAT16 (LBA)

/dev/sdb3 24576 7733247 3854336 83 Linux

dd'ed u-boot u-boot.sd to /dev/sdb1
mkfs.vfat'ed /dev/sdb2, mounted it, copied uImage there, umounted
mkfs.ext2'ed /dev/sdb3, mounted it, and untared (tar xfvj) the rootfs.tar.bz2 to it, umounted

Now I think there is something wrong with my bootargs, this is how I try to boot:

-> fatload mmc 0:2 0x42000000 /uImage

-> setenv bootargs console=ttySP0,115200 noinitrd root=/dev/mmcblk0p3 rootfstype=ext2 rw

-> bootenv

thx

The console should be:

console=ttyAM0 , if you use 2.6.35 kernel from Freescale

console=ttyAMA0, if you use a mainline kernel.
