- Select the software release
Yocto Build U-Boot from source code
Toolchain installation for out of Yocto builds
To install the toolchain, follow the Yocto Toolchain installation guide.
Build U-Boot out of Yocto tree
Obtain sources:
$ git clone https://github.com/varigit/uboot-imx.git -b lf_v2024.04_6.6.23-2.0.0_var01 $ cd uboot-imx
Configure compilation environment:
$ source /opt/fsl-imx-xwayland/6.6-scarthgap/environment-setup-armv8a-poky-linux
Cleanup everything:
$ make mrproper
Select configuration:
$ make imx95_var_dart_defconfig
Build U-Boot:
$ make -j$(nproc)
Download and install Arm-none-eabi cross-compiler required to build OEI and SM
$ wget https://developer.arm.com/-/media/Files/downloads/gnu/13.2.Rel1/binrel/arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi.tar.xz $ sudo tar -xf arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi.tar.xz -C /opt
Build boot image
The final boot image contains multiple firmware files, as explained by NXP in IMX_LINUX_USERS_GUIDE.pdf (Search for "How to build imx-boot image by using imx-mkimage").
The following procedure builds the final image:
Create imx-boot-tools directory:
$ mkdir imx-boot-tools $ cd imx-boot-tools
Download imx_mkimage:
$ git clone https://github.com/nxp-imx/imx-mkimage -b lf-6.6.23-2.0.0
Download DDR firmware:
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.24-fbe0a4c.bin $ chmod +x firmware-imx-8.24-fbe0a4c.bin $ ./firmware-imx-8.24-fbe0a4c.bin $ rm firmware-imx-8.24-fbe0a4c.bin $ cp firmware-imx-8.24-fbe0a4c/firmware/ddr/synopsys/* imx-mkimage/iMX95
Download ELE firmware:
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-ele-imx-0.1.2-4ed450a.bin $ chmod +x firmware-ele-imx-0.1.2-4ed450a.bin $ ./firmware-ele-imx-0.1.2-4ed450a.bin $ rm firmware-ele-imx-0.1.2-4ed450a.bin $ cp firmware-ele-imx-0.1.2-4ed450a/mx95a0-ahab-container.img imx-mkimage/iMX95
Download and build ATF:
$ git clone https://github.com/varigit/imx-atf -b lf_v2.10_6.6.23-2.0.0_var01 $ cd imx-atf $ source /opt/fsl-imx-xwayland/6.6-scarthgap/environment-setup-armv8a-poky-linux $ unset LDFLAGS $ make PLAT=imx95 bl31 $ cp build/imx95/release/bl31.bin ../imx-mkimage/iMX95 $ cd ..
Download and build OEI DDR Image and OEI TCM Image:
$ git clone https://github.com/varigit/imx-oei -b lf-6.6.23-2.0.0_var01 $ cd imx-oei $ export OEI_CROSS_COMPILE=/opt/arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi/bin/arm-none-eabi- $ make really-clean $ make board=mx95lp5 DEBUG=0 oei=ddr $ cp build/mx95lp5/ddr/oei-m33-ddr.bin ../imx-mkimage/iMX95 $ make board=mx95lp5 DEBUG=0 oei=tcm $ cp build/mx95lp5/tcm/oei-m33-tcm.bin ../imx-mkimage/iMX95 $ cd ..
Download and build SM:
$ git clone https://github.com/varigit/imx-sm -b lf-6.6.23-2.0.0_var01 $ cd imx-sm $ export SM_CROSS_COMPILE=/opt/arm-gnu-toolchain-13.2.Rel1-x86_64-arm-none-eabi/bin/arm-none-eabi- $ make really-clean $ make -j $(nproc --all) config=mx95evk cfg $ make -j $(nproc --all) config=mx95evk img $ cp build/mx95evk/m33_image.bin ../imx-mkimage/iMX95 $ cd ..
Copy U-Boot binaries:
$ cp ../u-boot.bin imx-mkimage/iMX95 $ cp ../spl/u-boot-spl.bin imx-mkimage/iMX95
Build boot image:
$ cd imx-mkimage $ make clean $ make SOC=iMX95 flash_a55 REV=A0 OEI=YES LPDDR_TYPE=lpddr5 LPDDR_FUNC=train $ mv iMX95/flash.bin iMX95/imx-boot-sd.bin
Install the built U-Boot on an SD card
$ sudo dd if=iMX95/imx-boot-sd.bin of=/dev/sdX bs=1K seek=32 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 iMX95/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
