2. Build guide

2.1 Install cross compiler

ARTIK710

• You'll need an arm64 cross compiler

sudo apt-get install gcc-aarch64-linux-gnu device-tree-compiler

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

ARTIK530

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 Build the u-boot with helper script of build-artik

ARTIK710

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

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

ARTIK530

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

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

2.3 Build the u-boot with manual way

ARTIK710

make ARCH=arm artik710_raptor_defconfig
make ARCH=arm CROSS_COMPILE=aarch64-linux-gnu-

ARTIK530

make ARCH=arm artik530_raptor_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-

2.4 Generate params.bin

The params.bin contains u-boot environment variables and you can generate the file using below commands:

ARTIK710

cp `find . -name "env_common.o"` copy_env_common.o
aarch64-linux-gnu-objcopy -O binary --only-section=.rodata.default_environment `find . -name "copy_env_common.o"`
tr '\0' '\n' < copy_env_common.o | grep '=' > default_envs.txt
cp default_envs.txt default_envs.txt.orig
tools/mkenvimage -s 16384 -o params.bin default_envs.txt

ARTIK530

cp `find . -name "env_common.o"` copy_env_common.o
arm-linux-gnueabihf-objcopy -O binary --only-section=.rodata.default_environment `find . -name "copy_env_common.o"`
tr '\0' '\n' < copy_env_common.o | grep '=' > default_envs.txt
cp default_envs.txt default_envs.txt.orig
tools/mkenvimage -s 16384 -o params.bin default_envs.txt

2.5 Generate fip/nexell compatable image

The u-boot-dtb.bin cannot be loaded by bl1/bl2 bootloaders. You have to generate a fip image and boot image for nexell bl1.

ARTIK710

• generate a fip-nonsecure.bin image using fip_create tool(input: u-boot-dtb.bin, output:fip-nonsecure.bin)

tools/fip_create/fip_create \
	--dump --bl33 u-boot-dtb.bin \
	fip-nonsecure.bin

• generate a fip-nonsecure.img using SECURE_BINGEN tool(input: fip-nonsecure.bin, output: fip-nonsecure.img)

tools/nexell/SECURE_BINGEN \
	-c S5P6818 -t 3rdboot \
	-n tools/nexell/nsih/raptor-64.txt \
	-i fip-nonsecure.bin \
	-o fip-nonsecure.img \
	-l 0x7df00000 -e 0x00000000

ARTIK530

• generate a bootloader.img using BOOT_BINGEN tool

tools/nexell/SECURE_BINGEN \
	-c S5P4418 -t 3rdboot \
	-n tools/nexell/nsih/raptor-sd.txt \
	-i u-boot-dtb.bin \
	-o bootloader.img \
	-l 0x94c00000 -e 0x94c00000

3. Update Guide

You can update the u-boot through fastboot or micro sd card(ext4 partition)

3.1 Fastboot

You should prepare a micro USB cable to connect between the board and host PC

• Install android-tools-fastboot

sudo apt-get install android-tools-fastboot
wget -S -O - http://source.android.com/source/51-android.rules | sed "s/<username>/$USER/" | sudo tee >/dev/null /etc/udev/rules.d/51-android.rules; sudo udevadm control --reload-rules

• Insert the USB cable(not MicroUSB Cable) into your board. Enter u-boot shell mode during boot countdown:

Net:   No ethernet found.
Hit any key to stop autoboot:  0
ARTIK710 #
ARTIK710 #
ARTIK710 # fastboot 0

ARTIK710

• You'll need to upload the partmap_emmc.txt prior than uploading the binaries. It can be downloaded from boot-firmwares-artik710. On your Host PC(Linux), flash the u-boot using below command

sudo fastboot flash partmap partmap_emmc.txt
sudo fastboot flash fip-nonsecure fip-nonsecure.img
sudo fastboot flash env params.bin
sudo fastboot reboot

ARTIK530

• You'll need to upload the partmap_emmc.txt prior than uploading the binaries. It can be downloaded from boot-firmwares-artik530. On your Host PC(Linux), flash the u-boot using below command

sudo fastboot flash partmap partmap_emmc.txt
sudo fastboot flash bootloader bootloader.img
sudo fastboot flash env params.bin
sudo fastboot reboot

3.2 microSD Card

Prepare a micro SD card and format to ext4 file system.

sudo mkfs.ext4 /dev/sd[X]1
sudo mount /dev/sd[X]1 /mnt

ARTIK710

• Copy compiled binaries(fip-nonsecure.img, params.bin) into a micro sd card.

sudo cp fip-nonsecure.img params.bin partmap_emmc.txt /mnt
sudo umount /mnt

• Insert the microSD card into your board and enter u-boot shell during boot countdown

sd_recovery mmc 1:1 48000000 partmap_emmc.txt

ARTIK530

• Copy compiled binaries(bootloader.img, params.bin) into a micro sd card.

sudo cp bootloader.img params.bin partmap_emmc.txt /mnt
sudo umount /mnt

• Insert the microSD card into your board and enter u-boot shell during boot countdown
