We are try to flash uboot in emmc using dd command on imx8mp using below command.

/bin/echo 0 > /sys/block/mmcblk2boot0/force_ro
/bin/dd if=/dev/zero of=/dev/mmcblk2boot0 bs=1k count=5000 conv=fsync
/bin/sync &
/bin/dd if=imx-boot-imx8mp-35som-sd.bin-flash_evk of=/dev/mmcblk2boot0 bs=1024 seek=32 conv=fsync
/bin/sync &
/bin/echo 1 > /sys/block/mmcblk2boot0/force_ro

/usr/bin/mmc bootpart enable 1 1 /dev/mmcblk2

But this not working for emmc.

Uboot flash dd command perfectly working with sd card. but not working with emmc.

any idea about this ?
