Linux Device Drivers Development

Building your kernel

Building the kernel requires you to specify the architecture for which it is built, as well as the compiler. That said, it is not necessary for a native build:

ARCH=arm make imx_v6_v7_defconfig
ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- make zImage -j16  

After that, you will see something like:

    [...]
      LZO     arch/arm/boot/compressed/piggy_data
      CC      arch/arm/boot/compressed/misc.o
      CC      arch/arm/boot/compressed/decompress.o
      CC      arch/arm/boot/compressed/string.o
      SHIPPED arch/arm/boot/compressed/hyp-stub.S
      SHIPPED arch/arm/boot/compressed/lib1funcs.S
