Hi, I would like to apply PREEMPT-RT patch for i.mx6ul board in yocto.
However I was not able to do it, so I would like you to tell me the way.
Right now I use yocto 2.0 (Jethro).
I found linux-yocto-rt_4.1.bb file in sources/poky/meta/recipes-kernel/linux.
After bitbake I checked $ uname -a, but it did not say PREEMPT RT.
I think I would be able to make preempt rt kernel image if I could correctly apply linux-yocto-rt_4.1.bb.
How can I apply the recipe ? Or if there are other way to make preempt rt kernel image, would you tell me the way please?
And I found a readme file which says "In order to build the image with the linux-yocto-rt kernel, be sure to include the following line in your local.conf, bblayers.conf, or your $MACHINE.conf.
PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-rt" " in sources/poky/meta/recipes-rt.
So I added the line in my bblayers.conf and local.conf, but I could not make rt image.
In the readme file, it also says about core-image-minimal. It means that we can use linux-yocto-rt only in core-image-minimal image? I would like to use other image.
Furthermore, I found linux-fslc-mx6-rt_3.14-1.0.x.bb in sources/meta-fsl-arm/receipes-kernel/linux.
Does it have relation?
Thank you for reading.
I am looking forward to your reply.
