1. Introduction

This 'linux-artik' repository is linux kernel source for artik5(artik520), artik10(artik1020), artik710 and artik530. The base kernel version of artik5 and artik10 is linux-3.10.93 and based on Samsung Exynos kernel. The artik710 and artik530 kernel is based on is based on linux-4.4.43.

2. Build guide

2.1 Install cross compiler

ARTIK710/710S

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

ARTIK5, ARTIK10, ARTIK530(S) and ARTIK533S

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

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/arm-linux-gnueabihf/gcc-linaro-5.4.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
tar xf gcc-linaro-5.4.1-2017.05-x86_64_arm-linux-gnueabihf.tar.xz
export PATH=~/gcc-linaro-5.4.1-2017.05-x86_64_arm-linux-gnueabihf/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 u-boot with helper script of build-artik

ARTIK710

cd build-artik
./build_kernel.sh -b artik710

You can find the u-boot binaries from the build-artik/output/images/artik710/

ARTIK710S

cd build-artik
./build_kernel.sh -b artik710s

You can find the u-boot binaries from the build-artik/output/images/artik710s/

ARTIK530

cd build-artik
./build_kernel.sh -b artik530

You can find the u-boot binaries from the build-artik/output/images/artik530/

ARTIK530S

cd build-artik
./build_kernel.sh -b artik530s

You can find the u-boot binaries from the build-artik/output/images/artik530s/

ARTIK533S

cd build-artik
./build_kernel.sh -b artik533s

You can find the u-boot binaries from the build-artik/output/images/artik533s/

ARTIK5

cd build-artik
./build_kernel.sh -b artik5

You can find the u-boot binaries from the build-artik/output/images/artik5/

ARTIK10

cd build-artik
./build_kernel.sh -b artik10

You can find the u-boot binaries from the build-artik/output/images/artik10/

2.3 Build the u-boot with manual way

ARTIK710/710S

make ARCH=arm64 artik710_raptor_defconfig

If you want to change kernel configurations,

make ARCH=arm64 menuconfig

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- Image -j4
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- dtbs
mkdir usr/modules
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- modules -j4
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- modules_install INSTALL_MOD_PATH=usr/modules INSTALL_MOD_STRIP=1
make_ext4fs -b 4096 -L modules \
	-l 32M usr/modules.img \
	usr/modules/lib/modules/
rm -rf usr/modules

ARTIK530/530S/533S

make ARCH=arm artik530_raptor_defconfig

If you want to change kernel configurations,

make ARCH=arm menuconfig

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage -j4
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- dtbs
mkdir usr/modules
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules -j4
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules_install INSTALL_MOD_PATH=usr/modules INSTALL_MOD_STRIP=1
make_ext4fs -b 4096 -L modules \
	-l 32M usr/modules.img \
	usr/modules/lib/modules/
rm -rf usr/modules

ARTIK5

make ARCH=arm artik5_defconfig

If you want to change kernel configurations,

make ARCH=arm menuconfig

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage -j4
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- exynos3250-artik5.dtb
./scripts/mk_modules.sh

ARTIK10

make ARCH=arm artik10_defconfig

If you want to change kernel configurations,

make ARCH=arm menuconfig

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage -j4
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- exynos5422-artik10.dtb
./scripts/mk_modules.sh

3. Update Guide
