How to configure

1. Change current directory

cd path/to/kernel/source

2. Configure kernel with menuconfig

make ARCH=arm B610s_defconfig

make menuconfig ARCH=arm 

3. Overwrite defconfig

mv -f .config arch/arm/B610s_defconfig

4. Cleaning

make mrproper

How to build

0. Get cross compiler

I recommend linaro.org one
https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/armeb-eabi

wget https://releases.linaro.org/components/toolchain/binaries/4.9-2017.01/armeb-eabi/gcc-linaro-4.9.4-2017.01-x86_64_armeb-eabi.tar.xz
tar xvf gcc-linaro-4.9.4-2017.01-x86_64_armeb-eabi.tar.xz

1. Set some variables

export PATH=$PATH:/path/to/gcc-linaro-4.9.4-2017.01-x86_64_arm-eabi/bin

export CROSS_COMPILE=arm-eabi-

2. Prepare config file

make ARCH=arm O=output B610s_defconfig

3. Build kernel

make ARCH=arm O=output -j8

If you finish building, you can find zImage in output/arch/arm/boot/zImage
