Hi gusarakbula,
I have install toolchain. I'm entering kernel folder as below:
~/fsl/build/tmp/work/imx6qsabresd-poky-linux-gnueabi/linux-imx/3.14.28-r0/git
However, we type make to compile kernel, the system will show some configuration as below:
How should we choose these?
Note: bitbake to compile no this situation.
