Yocto Build U-Boot from source code

Toolchain installation for out of Yocto builds

To install the toolchain, follow Yocto Toolchain installation.

Build U-Boot out of Yocto tree

Obtain sources:

$ git clone https://github.com/varigit/uboot-imx.git -b imx_v2018.03_4.14.98_2.0.0_ga_var01
$ cd uboot-imx

Configure compilation environment:

$ source /opt/fsl-imx-xwayland/4.14-sumo/environment-setup-aarch64-poky-linux

Cleanup everything:

$ make mrproper

Select configuration:

$ make imx8qxp_var_som_defconfig

Build U-Boot:

$ make -j4

Build boot image

The final boot image contains multiple firmware files. The following procedure builds the final image.

Create imx-boot-tools directory:

$ mkdir imx-boot-tools
$ cd imx-boot-tools

Obtain SC firmware:
Either build it by following the Build SCFW from source code page, or just download the pre-built binary by running:

$ wget https://github.com/varigit/meta-variscite-imx/raw/sumo-imx-4.14.98-var01/recipes-bsp/imx-sc-firmware/imx-sc-firmware/mx8qx-var-som-scfw-tcm.bin -O scfw_tcm.bin

Download SECO firmware:

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.1.1.bin
$ chmod +x firmware-imx-8.1.1.bin
$ ./firmware-imx-8.1.1.bin --auto-accept --force
$ cp firmware-imx-8.1.1/firmware/seco/mx8qx-ahab-container.img .

Download and build imx_mkimage:

$ git clone https://github.com/nxp-imx/imx-mkimage -b imx_4.14.98_2.0.0_ga
$ cd imx-mkimage
$ make 
$ cp mkimage_imx8 iMX8QX/soc.mak iMX8QX/*.sh scripts/pad_image.sh ..
$ cd ..

Download and build ATF:

$ git clone https://github.com/nxp-imx/imx-atf -b imx_4.14.98_2.0.0_ga

$ cd imx-atf
$ source /opt/fsl-imx-xwayland/4.14-sumo/environment-setup-aarch64-poky-linux
$ export LDFLAGS=

$ make PLAT=imx8qx bl31
$ cp build/imx8qx/release/bl31.bin ..
$ cd ..

Copy U-Boot binaries:

$ cp ../tools/mkimage mkimage_uboot
$ cp ../u-boot.bin .

Build boot image:

$ make -f soc.mak clean
$ make -f soc.mak SOC=iMX8QX MKIMG=./mkimage_imx8 PAD_IMAGE=./pad_image.sh flash
$ mv flash.bin imx-boot-sd.bin

Install the built U-Boot on an SD card

$ sudo dd if=imx-boot-sd.bin of=/dev/sdX bs=1K seek=32 conv=fsync

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 imx-boot-sd.bin /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)

Update your U-Boot out of Yocto tree

$ git pull
