Hi Bas and Gabriele, Thank you so much for you advice.

Compile it in kernel source like using following command? make ARCH=arm imx_v6_v7_defconfig > It is maybe a bit complex, but it saves cloning the kernel for the sake > of just adding a single DTS with defconfig and a few patches. That is procedure I was looking for. > Hope this helps, Great helps, thank you so much. - jupiter > Bas. > -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
