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/7894b625259b89cd117685a0855a2c84...
