[U-Boot] Issue with uboot on imx6slevk

[Arthur Lambert]

Hi,

I would like to use Buildroot to generate a linux for imx6 sololitevk.
I found an existing configuration done for this board in the master
branch of Buildroot.

To generate my image :

make freescale_imx6sololiteevk_defconfig
make all

Then I used this script in
board/freescale/imx6sabresd/create-boot-sd.sh to generate an sd card
by typing :

sudo ./create-boot-sd.sh /dev/mmcblk0

When I tried to run my sdcard on the board current result is :

Is it normal ? Do I wrong somewhere in my process ?
Do I must add a patch on uboot to fix that ?
I see some stuff like this for example :
https://gitorious.org/rowboat/u-boot/commit/7894b625259b89cd117685a0855a2c84b11a38f5
