imx6UL evk with kernel 4.1

[matt67]

Hello all,

I'm testing the imx6UL evk with yocto and I'm wondering if it is easy to change the kernel provider to build 4.1 kernel.

Currently with jethro, the machine conf of imx6UL evk uses the linux-imx (which is 3.14) and I would like to switch to 4.1 kernel.

What do you think about that ? and what's the easiest way to do it (changing virtual/kernel provider to linux-flsc) ?

Regards,

Matt

Hello Fabio,

Thanks for your support, I created a custom recipes with this version of the kernel and it worked !

Hello Matt,

I have the same problem

Do you change setting like

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

I use these setting

but my kernel is 3.0.35

You better should use a new repo like I did with imx-4.1.15-1.0.0_ga.

But the way to change the kernel provider also worked for me.

Hi Matt

We have the same manifest.xml.

But I don't know why I use uname -a command shows up like these?

[Yuri]

Hello,

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

Regards

Yuri

[yichen]

Hi Yuri,

I don't know how to use clean build as you said.

[Yuri]

  To buid Your system, please follow "Freescale_Yocto_Project_User's_Guide.pdf",

section 3 (Host Setup) and 4 (Yocto Project Setup), assuming there is no "fsl-release-bsp"

directory on Your home folder.

Regards,

Yuri.

You can use 4.1.15 GA kernel from:

http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/log/?h=imx_4.1.15_1.0.0_ga

Thank you, Fabio!
