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
