== Build ==

==== Set toolchain ====
Export [[iMX6 TinyRex Toolchain|toolchain variables]] for every related terminal session.

==== Initial steps ====
Create working directory
<syntaxhighlight lang="bash">
mkdir -pv ~/workdir/imx6/bootloader/
</syntaxhighlight>

== U-Boot v2015.04 ==

=== Download and extract source code ===
<syntaxhighlight lang="bash">
cd ~/workdir/imx6/bootloader/
git clone -b uboot-imx-v2015.04 --single-branch https://github.com/voipac/uboot-imx uboot-imx-v2015.04-rex
cd uboot-imx-v2015.04-rex
</syntaxhighlight>

=== Compile ===
Output file is called u-boot.imx. All the compiled images are intended for production usage.
