U-Boot is a bootloader responsible for hardware initialization, loading and booting Linux kernel. It is also used for module 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 mx6tinyrexultra_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-tinyrexultra.imx

Compile for SD3 and Android 7.x

cd ~/workdir/imx6/bootloader/uboot-imx-v2015.04-rex
make distclean
make mx6tinyrexultraandroid_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-tinyrexultraandroid.imx

Compile for SPI1 and Linux/Yocto

cd ~/workdir/imx6/bootloader/uboot-imx-v2015.04-rex
make distclean
make mx6tinyrexultrarecovery_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-tinyrexultrarecovery.imx

Compile for SATA

cd ~/workdir/imx6/bootloader/uboot-imx-v2015.04-rex
make distclean
make mx6tinyrexultrasata_config
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi-
cp -av u-boot.imx /srv/tftp/imx6/u-boot-imx6-tinyrexultrasata.imx

How to Flash a new version

Flash Normal image into SD3

sudo dd if=u-boot-imx6-tinyrex*.imx of=/dev/sdc bs=1k seek=1 skip=0 oflag=dsync

Flash Recovery image into SPI1

setenv ipaddr 192.168.0.150
setenv serverip 192.168.0.1
mw.b 0x10800000 0xFF 0x80000
