i.MX8M nano U-Boot image error occurs

shinji_tonoshit — Wed, 11 Feb 2026 01:01:36 GMT

Hi All,

When running imx-mkimage, an error occurs.
"Error: Bad parameters for FIT image type"
The following command was executed.
I have attached the executed script and logs.
+++++
cd imx-mkimage
cp ../uboot-imx/spl/u-boot-spl.bin iMX8M
cp ../uboot-imx/u-boot-nodtb.bin iMX8M
cp ../uboot-imx/arch/arm/dts/imx8mn-evk.dtb iMX8M
cp ../imx-atf/build/imx8mn/release/bl31.bin iMX8M
cp ../firmware-imx/firmware-imx-8.20/firmware/ddr/synopsys/lpddr4_pmu_train_* iMX8M
cp ../uboot-imx/tools/mkimage iMX8M/mkimage_uboot

make SOC=iMX8MN DEV=flexspi flash_evk
+++++

Best Regards,
Shinji

Hello,

please try by using the following make command instead:
make SOC=iMX8MN flash_evk_flexspi

Best regards/Saludos,
Aldo.

Dear Aldo,

Thank you for your reply.
I built using `make SOC=iMX8MN flash_evk_flexspi`, but the issue persists.

Use ‘-T list’ to see a list of available image types
Long options are available; read the man page for details
make[1]: *** [soc.mak:163: u-boot.itb] Error 1
make: *** [Makefile:26: flash_evk_flexspi] Error 2

I have attached the shell script and build log.
Please advise on a solution.

Hello,

Please see below the steps I follow for creating an image, I think the error you are seeing are due to the version mismatch.

EDIT: fixed the typo

### Clone imx-mkimage it is better to download the same version of the sw we are working with ###
git clone https://github.com/nxp-imx/imx-mkimage -b lf-6.1.22_2.0.0

### Decompress the GNU toolchain into a path in local disk, in this test would be /opt/ ###
sudo tar -xvJf arm-gnu-toolchain-12.3.rel1-x86_64-aarch64-none-linux-gnu.tar.xz -C /opt

### Clone and build Uboot ###
cd ..
git clone https://github.com/nxp-imx/uboot-imx -b lf-6.1.22-2.0.0
cd uboot-imx
make -j $(nproc --all) clean
make -j$(nproc --all) ARCH=arm CROSS_COMPILE=/opt/arm-gnu-toolchain-12.3.rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- imx8mn_evk_defconfig
make -j $(nproc --all) ARCH=arm CROSS_COMPILE=/opt/arm-gnu-toolchain-12.3.rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-

wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.20.bin
chmod +x firmware-imx-8.20.bin
./firmware-imx-8.20.bin --auto-accept

### Clone and build ATF ###
git clone https://github.com/nxp-imx/imx-atf -b lf-6.1.22-2.0.0
cd imx-atf
make -j $(nproc --all) PLAT=imx8mn bl31 CROSS_COMPILE=/opt/arm-gnu-toolchain-12.3.rel1-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu-

### Copy the resulting binaries to imx-mkimage ###
cp ~/uboot-imx/spl/u-boot-spl.bin ~/imx-mkimage/iMX8M
cp ~/uboot-imx/u-boot-nodtb.bin ~/imx-mkimage/iMX8M
cp ~/uboot-imx/arch/arm/dts/imx8mn-evk.dtb ~/imx-mkimage/iMX8M
cp ~/imx-atf/build/imx8mn/release/bl31.bin ~/imx-mkimage/iMX8M
cp ~/uboot-imx/tools/mkimage ~/imx-mkimage/iMX8M/mkimage_uboot

### Copy i.MX firmware ###
cp ./firmware-imx-8.20/firmware/ddr/synopsys/lpddr4_*.bin ~/imx-mkimage/iMX8M

### Build the flash.bin using mkimage ###
cd imx-mkimage
make SOC=iMX8MN flash_evk_flexspi

Best regards/Saludos,
Aldo.

Dear Aldo,

Thank you for your reply.
I followed the steps you provided to build, but an error occurs when executing the following command.
Please advise on how to resolve this.
1)git clone https://github.com/nxp-imx/uboot-imx -b lf-6.1.22_2.0.0
Cloning into ‘uboot-imx’...
fatal: Remote branch lf-6.1.22_2.0.0 not found in upstream origin
2)git clone https://github.com/nxp-imx/imx-atf -b lf-6.1.22_2.0.0
Cloning into ‘imx-atf’...
fatal: Remote branch lf-6.1.22_2.0.0 not found in upstream origin

Best Regards,
Shinji.

Hello,

I tried on my side and did create the flash.bin correctly, I'm not using your bash script but I do not think this could be the issue but could you try using one by one the commands?

Also, please double check that all the files are correctly copied.

Best regards/Saludos,
Aldo.
