How to configure u-boot for emmc.

emb-bharpay — Fri, 08 Jan 2021 06:22:10 GMT

Hello Team,

I have done the following implementation to configure u-boot for emmc:

$ echo "UBOOT_CONFIG = \"emmc\"" >> conf/local.conf

which gives the error that I have attached with this query.

For resolving that error I have done the following changes in imx8qmmek.conf.

UBOOT_CONFIG ??= "emmc"

UBOOT_CONFIG[emmc] = " imx8qm_mek_defconfig,sdcard"

Given the following command:

bitbake -c compile -f u-boot-imx

bitbake -c deploy u-boot-imx

bitbake core-image-minimal

After that my image get build successfully.

But now the issue is that instead of "imx-boot-imx8qmmek-emmc.bin-flash_spl", yocto is building " imx-boot-imx8qmmek-emmc.bin-flash_spl_flexspi" which I am not able to flash on the target.

Can anyone help me with this?

FYI: Using iMX8QM-MEK board.

Thanks & Regards,

Payal

do you mean you couldn't find "imx-boot-imx8qmmek-emmc.bin-flash_spl" if you build the new uboot? you only can find " imx-boot-imx8qmmek-emmc.bin-flash_spl_flexspi" ??

Yes, only "imx-boot-imx8qmmek-emmc.bin-flash_spl_flexspi" is there. It is not generating "imx-boot-imx8qmmek-emmc.bin-flash_spl"

I built imx-image-full for imx8qm. I add UBOOT_CONFIG[emmc] = " imx8qm_mek_defconfig,sdcard" in the imx8qmmek.conf, then use the command

"

"bitbake imx-image-full -c cleanall

bitbake imx-image-full "

I didn't reproduce this issue on my side, pls try again
