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 toolchain variables for every related terminal session.

Initial steps

Create working directory 

mkdir -pv ~/workdir/imx6/bootloader/

U-Boot v2015.04

Download and extract source code

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

Compile

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

Compile for SD3 and Linux/Yocto

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

Compile for SATA and Linux/Yocto

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

Compile for SD3 and Android 7.x

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

How to Flash a new version

Flash into SPI Flash using U-Boot

setenv ipaddr 192.168.0.150
setenv serverip 192.168.0.1
mw.b 0x10800000 0xFF 0x80000
tftp 0x10800000 imx6/u-boot-imx6-openrex*.imx
if sf probe 2:2; then sf erase 0x0 0x80000;sf write 0x10800000 0x400 0x7fc00; fi
