1. Introduction

Fork from 'linux-artik' repository adding Kitra530 and Kitra710C support.

2. Build guide

2.1 Install cross compiler

For Kitra530

sudo apt-get install gcc-arm-linux-gnueabihf

If you can't install the above toolchain, you can use linaro toolchain.

wget http://releases.linaro.org/components/toolchain/binaries/latest-5/arm-linux-gnueabihf/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf.tar.xz
tar xf gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf.tar.xz
export PATH=~/gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf/bin:$PATH

For Kitra710C

You'll need an arm64 cross compiler

sudo apt-get install gcc-aarch64-linux-gnu

If you can't install the above toolchain, you can use linaro toolchain.

wget https://releases.linaro.org/components/toolchain/binaries/5.4-2017.05/aarch64-linux-gnu/gcc-linaro-5.4.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz
tar xf gcc-linaro-5.4.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz
export PATH=~/gcc-linaro-5.4.1-2017.05-x86_64_aarch64-linux-gnu/bin:$PATH

You can the path permernently through adding it into ~/.bashrc

2.2 Install android-fs-tools

To generate modules.img which contains kernel modules, you can use the make_ext4fs.

sudo apt-get install android-tools-fsutils

2.2 Build the kernel

make ARCH=arm kitra530_defconfig
or
make ARCH=arm64 kitra710C_defconfig

If you want to change kernel configurations,

make ARCH=arm menuconfig #for KItra530
or
make ARCH=arm64 menuconfig #for Kitra710C

Run:

./mk_kernel.sh
./mk_dtb.sh
./mk_modules.sh

3. Update Guide

Copy compiled binaries into your board.

scp arch/arm/boot/zImage root@{YOUR_BOARD_IP}:/root
scp arch/arm/boot/dts/s5p4418*.dtb root@{YOUR_BOARD_IP}:/root
scp usr/modules.img root@{YOUR_BOARD_IP}:/root

On KItra530

mount -o remount,rw /boot
cp /root/zImage /boot
cp /root/s5p4418*.dtb /boot
dd if=/root/modules.img of=/dev/mmcblk0p5
sync
reboot

On KItra710C

mount -o remount,rw /boot
cp /root/Image /boot
cp /root/*.dtb /boot
dd if=/root/modules.img of=/dev/mmcblk0p5
sync
reboot
