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 lf_v2022.04_var01
$ cd uboot-imx

Configure compilation environment:

$ source /opt/fslc-xwayland/3.3/environment-setup-cortexa53-crypto-fslc-linux

Cleanup everything:

$ make mrproper


Select configuration:

$ make imx8mq_var_dart_defconfig

Build U-Boot:

$ make -j$(nproc)

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

Download DDR and HDMI firmware:

$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.16.bin
$ chmod +x firmware-imx-8.16.bin
$ ./firmware-imx-8.16.bin
$ cp firmware-imx-8.16/firmware/ddr/synopsys/* .
$ cp firmware-imx-8.16/firmware/hdmi/cadence/signed_* .

Download imx_mkimage:

$ git clone https://github.com/nxp-imx/imx-mkimage -b lf-5.15.32_2.0.0
$ cp imx-mkimage/iMX8M/*.c imx-mkimage/iMX8M/*.sh  imx-mkimage/scripts/*.sh .
$ cp dtb_check.sh ../scripts/

Download and build ATF:

$ git clone https://github.com/varigit/imx-atf -b lf_v2.6_var01 
$ git clone https://github.com/varigit/meta-variscite-bsp -b kirkstone
$ cd imx-mkimage

$ git apply ../meta-variscite-bsp/recipes-bsp/imx-mkimage/imx-boot/0001-iMX8M-soc-allow-dtb-override.patch
$ git apply ../meta-variscite-bsp/recipes-bsp/imx-mkimage/imx-boot/0002-iMX8M-soc-change-padding-of-DDR4-and-LPDDR4-DMEM-fir.patch $ cp iMX8M/soc.mak .. $ cd .. $ cd imx-atf $ source /opt/fslc-xwayland/3.3/environment-setup-cortexa53-crypto-fslc-linux $ unset LDFLAGS $ make PLAT=imx8mq bl31 $ cp build/imx8mq/release/bl31.bin .. $ cd ..

Copy U-Boot binaries:

$ cp ../tools/mkimage mkimage_uboot
$ cp ../u-boot.bin .
$ cp ../u-boot-nodtb.bin ../spl/u-boot-spl.bin ../arch/arm/dts/imx8mq-var-dart-dt8mcustomboard.dtb .

Build boot image:

$ make -f soc.mak clean
$ make -f soc.mak SOC=iMX8MQ dtbs=imx8mq-var-dart-dt8mcustomboard.dtb MKIMG=./mkimage_imx8 PAD_IMAGE=./pad_image.sh CC=gcc OUTIMG=imx-boot-sd.bin flash_evk 

Install the built U-Boot on an SD card


$ sudo dd if=imx-boot-sd.bin of=/dev/sdX bs=1K seek=33 conv=fsync

(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 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
