Basic Kernel Compilation

Install the cross-compile toolchain

Download from:

• https://licheepizero.us/arm-linux-gnueabihf/ (Mirror)
• https://releases.linaro.org/components/toolchain/binaries/6.3-2017.05/arm-linux-gnueabihf/

Use the following commands to install:

• wget https://licheepizero.us/arm-linux-gnueabihf/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
• tar xvf gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
• mv gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf /opt/
• vim /etc/bash.bashrc
• add: PATH="$PATH:/opt/gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf/bin"
• arm-linux-gnueabihf-gcc -v

Download and Compile the Kernel:

(default branch is zero-4.10.y):

• git clone https://github.com/Lichee-Pi/linux.git
  (or you can download a tar.gz made at the time of the posting of this: here)
• cd linux
• make ARCH=arm licheepi_zero_defconfig
• make ARCH=arm menuconfig #add bluethooth, etc.
• make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16
• make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 INSTALL_MOD_PATH=out modules
• make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j16 INSTALL_MOD_PATH=out modules_install

After a success compilation，the zImage can be found under 'arch/arm/boot/' and the driver .ko file will be under 'out/'
