Buildroot on mx6slevk

Question asked by Arthur LAMBERT on Dec 26, 2014

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 :

 

reading uImage

5258568 bytes read in 267 ms (18.8 MiB/s)

Booting from mmc ...

reading imx6sl-evk.dtb

## Booting kernel from Legacy Image at 80800000 ...

   Image Name:   Linux-3.10.17

   Image Type:   ARM Linux Kernel Image (uncompressed)

    MAYBE you should read doc/README.arm-unaligned-accesses

Is it normal ? Do I wrong somewhere in my process ?

Do I must add a patch on uboot-imx to fix that ?

I see some stuff like this for example :

Thanks & Regards,

Arthur.
