The problem is not flashing into emmc 

when i check the mmc list its showing 

mmc list
FSL_SDHC: 1
FSL_SDHC: 2

FSL_SDHC:2 is my emmc but its taking the first one what could be the reason for this

in the uuu file i have added manually to flash to emmc dev 2

FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev 1
FB: ucmd mmc dev 1
FB: flash -raw2sparse all core-image-weston-imx8mp-lpddr4-evk.wic.bz2
FB: flash bootloader imx-boot-imx8mp-lpddr4-evk-sd.bin-flash_evk
FB: ucmd if env exists emmc_ack; then ; else setenv emmc_ack 0; fi;
FB: ucmd mmc partconf 1 ${emmc_ack} 1 0
FB: done

Its not working

Hi @Cyriactoms!|

Thank you for contacting NXP Support!

What BSP version are you using?

What board are you using?

What commands are you using to flash your board?

Best Regards!

Chavira

[Cyriactoms]

BSP version 5.15
Iam using a custom som with imx8mp
I am using the script to flash which i have mentioned in the post
otherthan that iam using the command uuu -b emmc_all flash_evk image

HI @Cyriactoms!

Are you trying to flash our pre-compiled image to your board?

You should port our BSP to your board following our porting guide.

[Cyriactoms]

I build an yocto image using yocto project user guide for my imx8mp

[Chavira]

HI @Cyriactoms!

What machine target do you select when you compile the image?

Can you describe the steps that you followed to generate the image?

What BSP version are you using?

[Cyriactoms]

i am using the machine target as imx8mp_lpddr4_evk

I have followed the imx yocto build user guide

5.15

Hi @Cyriactoms!

The machine that you used works only in our iMX8MP-EVK board, you should port our BSP to your board following our porting guide.
