2. Build guide

2.1 Install cross compiler

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/4.9-2016.02/arm-linux-gnueabihf/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf.tar.xz
tar xf gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf
export PATH=~/gcc-linaro-4.9-2016.02-x86_64_arm-linux-gnueabihf/bin:$PATH

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

2.2 Build the u-boot

• For artik5>

make ARCH=arm artik5_config

If you want to change u-boot configurations, please change include/configs/artik5.h and include/configs/artik_common.h

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

• For artik10>

make ARCH=arm artik10_config

If you want to change u-boot configurations, please change include/configs/artik10.h and include/configs/artik_common.h

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

2.3 Generate params.bin

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

cp `find . -name "env_common.o"` copy_env_common.o
arm-linux-gnueabihf-objcopy -O binary --only-section=.rodata `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

3. Update Guide

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

3.1 Fastboot

For artik5, you should prepare mini-A(not microUSB) USB cable. For artik10, you should prepare Type-A to Type-A USB cable.

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

On your Host PC(Linux), flash the u-boot using below command

sudo fastboot flash bootloader u-boot.bin
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

Copy compiled binaries(u-boot.bin, params.bin) into a micro sd card.

sudo cp u-boot.bin params.bin /mnt
sudo umount /mnt

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