U-Boot (2017.09)

Before building kernel for Odroid Go advance on Ubuntu desktop, you need to install the required packages as follows.

host

$ sudo apt-get update &&\
sudo apt-get install -y git lzop build-essential gcc \
    bc libncurses5-dev libc6-i386 lib32stdc++6 zlib1g:i386

Download toolchain and extract the tarball to /opt/toolchains/.

host

$ sudo mkdir -p /opt/toolchains &&\
wget https://releases.linaro.org/components/toolchain/binaries/6.3-2017.05/aarch64-linux-gnu/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz &&\
sudo tar Jxvf gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz -C /opt/toolchains/

To set up information for compilation, paste below lines to $HOME/.bashrc.

host

export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
export PATH=/opt/toolchains/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/:$PATH

Execute the below command to apply the setting.

host

$ source ~/.bashrc

Check the toolchain version to confirm compatibility.

host

$ aarch64-linux-gnu-gcc -v
...
COLLECT_LTO_WRAPPER=/opt/toolchains/gcc-linaro-6.3.1-2017.02-x86_64_aarch64-linux-gnu/bin/../libexec/gcc/aarch64-linux-gnu/6.3.1/lto-wrapper
...
gcc version 6.3.1 20170109 (Linaro GCC 6.3-2017.02)

You can checkout U-Boot source tree from Hardkernel's Github.

$ git clone https://github.com/hardkernel/u-boot.git -b odroidgoA-v2017.09

Using a script make.sh, you can configure ODROID-GO-Advanced board of U-Boot.

If you use the latest u-boot source codes of Hardkernel Github after December 2020,
use odroidgoa option.
https://github.com/hardkernel/u-boot/commit/ac38b3f81d20b551eef5c230d7e87e7d5058e561

$ cd u-boot
$ ./make.sh odroidgoa

Or with old version,

$ cd u-boot
$ ./make.sh odroidgo2

Then, you will have the following img files in sd_fuse folder.

• idbloader.img
• uboot.img
• trust.img

We provide the script, u-boot/sd_fuse/sd_fusing.sh and this helps you to install bootloaders into your blank SD card.

1. Plug the Boot-Device (SD card) into the USB memory CARD reader and connect the USB memory card reader to your HOST PC (Linux OS).
2. Check the device path of your USB card reader.
3. Run this command to flash binaries into your SD card.

$ cd sd_fuse
$ ./sd_fusing.sh <device/path/of/your/card>

Here is an example.
If a device node of your USB card reader is assigned at /dev/sdc, install command will be as following.

$ cd sd_fuse
$ ./sd_fusing.sh /dev/sdc

Here is a boot.ini sample to run the latest u-boot with odroidgoa configuration.
