U-Boot is a bootloader responsible for hardware initialization, loading and booting Linux kernel. It is also used for SBC flashing.

== Build ==

==== Set toolchain ====
Export [[iMX6 OpenRex 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.

==== Compile for SD3 and Linux/Yocto ====
<syntaxhighlight lang="bash">
cd ~/workdir/imx6/bootloader/uboot-imx-v2015.04-rex
make distclean
make mx6openrexultra_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-openrexultra.imx
</syntaxhighlight>

==== Compile for SATA and Linux/Yocto ====
<syntaxhighlight lang="bash">
cd ~/workdir/imx6/bootloader/uboot-imx-v2015.04-rex
make distclean
make mx6openrexultrasata_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-openrexultrasata.imx
</syntaxhighlight>

==== Compile for SD3 and Android 7.x ====
<syntaxhighlight lang="bash">
cd ~/workdir/imx6/bootloader/uboot-imx-v2015.04-rex
make distclean
make mx6openrexultraandroid_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-openrexultraandroid.imx
</syntaxhighlight>

=== How to Flash a new version ===
==== Flash into SPI Flash using U-Boot ====
<syntaxhighlight lang="bash">
setenv ipaddr 192.168.0.150
setenv serverip 192.168.0.1
mw.b 0x10800000 0xFF 0x80000
