I am looking to generate the u-boot image by compiling das u-boot source using the below toolchain for imx8mm_evk_defconfig board, but didn't succeed. Any help in this regard would be appreciated. 

 

ToolChain Binaries used :

armv8l-linux-gnueabihf32-bit Armv8 Cortex-A, hard-float, little-endian

 

U-Boot Source :  SourceCode < U-Boot < DENX

 

 

ubuntu@ubuntu:~/embedded/nxp/toolchain/u-boot-2021.04-rc1$ make ARCH=arm64 CROSS_COMPILE=armv8l-linux-gnueabihf- distclean

Hello Sainis2,

For i.MX 8 builds on the host machine, set the environment with the following command before building.
source /opt/fsl-imx-xwayland//environment-setup-aarch64-poky-linux
export ARCH=arm64

u-uboot-2021.04 have not been evaluated you should continue to use 2020.04

 

Regards

It seems above mentioned steps are for yocto build, right? 

 

I am looking for building u-boot in conventional approach generating MLO, u-boot.img using the default board configuration: imx8mm_evk_defconfig under configs folder of u-boot source. I am able to build for default config board with below warnings but not able to generate the final image. Could you please help me in that regard? 

Objective : to boot only u-boot from sd-card on imx8mm_evk board. 

------------------------------------------------------------------------------------------------------------------------------------------

This board uses CONFIG_SPL_FIT_GENERATOR. Please migrate
to binman instead, to avoid the proliferation of
arch-specific scripts with no tests.

------------------------------------------------------------------------------------------------------------------------------------------

OBJCOPY spl/u-boot-spl-nodtb.bin
SYM spl/u-boot-spl.sym
CAT spl/u-boot-spl-dtb.bin
COPY spl/u-boot-spl.bin
WARNING 'lpddr4_pmu_train_1d_imem.bin' not found, resulting binary is not-functional
make[1]: Nothing to be done for 'SPL'.
