iMx6 kernel version

yichen — Tue, 17 May 2016 04:48:05 GMT

Hi all,

I followed the latest Freescale Yocto Project User's Guide build my image.

But when I use uname -a it shows up kernel 3.0.35

How can I change my kernel to 4.1?

Hello,

Do You use recommendations of the recent documentation package ?

In particular :

$ repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-4.1.15-1.0.0_ga

Have a great day,

Hello,

Pleae try using clean build (separate directoty) for the BSP.

Also, You may try demo image :

Hi Yuri

Thanks for your image

But still the same.

Is that caused by u-boot?

Because I have an emmc on my board. I don't know it will effect my kernel version or not?

Following image is boot by image you offered

Hello,

from just built Linux :

root@imx6qsabresd:~# uname -a

Linux imx6qsabresd 4.1.15-1.1.1+gd5d7c02 #1 SMP PREEMPT Tue May 17 16:33:36 OMST 2016 armv7l GNU/Linux

Looks like really eMMC located kernel and filesystem are used in the case.

Please check carefully Your boot settings and U-boot environment.

Difference between eMMC and SD is just port number.

Regards,

Yuri.

Hi Yuri,

Thanks for your help.

It is emmc's problem.

I change it to boot from sdcard to solved these problem.

Thanks!
