Hi jingyang xie,

You may need the command below to set the cross compile and architecture before execute the command "make"

export CROSS_COMPILE=~/<your path>/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-

export ARCH=arm

All the best

Hi jingyang xie,

After modifying the code, you need to locate the linux kernel directory(.../linux-imx/.../git/) in the terminal, and use the command "make".

All the best

Hi jingyang xie,

Chek this :Custom driver not building with the package

Best regards.

Hi jingyang xie,

You need to download the source code first, and then  modify the kernel code. Then build the source code. Here could you tell me which board and which version BSP are you using?
Have a great day,
Dan
