Before building with the cross compiler you must set up the cross compile tool by source /opt/fsl-imx-x11/<kernel>/environment-setup.....sh

thanks for the answer, how do i access the kernel menuconfig on the version
Linux 4.1.15?
i tried bitbake fsl-image-qt5 -c menuconfig but it does not work
I tried with bitbake -c menuconfig virtual / kernel, it works but we do not understand if it's the right way

can you tell me the file name you want to check for imx6sxscm-1gb-evb?
Thank you
Roberto

I prefer not to make it through Yocto, but directly cross-compiling it. First you must install meta-toolchain (you can follow task 7 at Yocto Training - HOME ) then go to kernel-source folder and

make imx_v7_defconfig

make menuconfig
