Yocto Build U-Boot from source code

1 Toolchain installation for out of Yocto builds

To install the toolchain, follow Yocto Toolchain installation.

2 Build U-Boot out of Yocto tree

Obtain sources:

$ git clone https://github.com/varigit/uboot-imx.git -b imx_v2015.04_4.1.15_1.1.0_ga_var03
$ cd uboot-imx

Configure compilation environment:

$ source /opt/fslc-x11/2.2.1/environment-setup-armv7at2hf-neon-fslc-linux-gnueabi

Cleanup everything:

$ make mrproper

Select one of the following configurations:

For booting from SD card/eMMC:
$ make mx6var_som_sd_defconfig

For booting from NAND flash:
$ make mx6var_som_nand_defconfig

Build U-Boot:

$ make -j$(nproc)


3 Install the built U-Boot on an SD card


$ sudo dd if=SPL of=/dev/sdX bs=1K seek=1; sync
$ sudo dd if=u-boot.img of=/dev/sdX bs=1K seek=69; sync

(Replace /dev/sdX with the correct device)

If you want to use our recovery SD card to flash the built U-Boot to NAND flash/eMMC, then copy it to the appropriate location in the SD card:

$ sudo cp SPL /media/rootfs/opt/images/…
$ sudo cp u-boot.img /media/rootfs/opt/images/…

And eject the SD card gracefully from host machine.


Note: If you manually upgrade an existing U-Boot, and you have an old environment saved, it is a good idea to reset your environment to the new default (see Environment handling commands)

4 Update your U-Boot out of Yocto tree

$ git pull
