U-boot for ARTIK5 and ARTIK10
Contents
1. Introduction
This 'u-boot-artik' repository is u-boot source for artik5(artik520) and artik10(artik1020). The base version of artik u-boot is 2012-07 and based on Samsung Exynos u-boot.
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

USB cable Connected![CH-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
