Hello , 

I'm encoutering the same behaviour on IMX8  board with builded HardKnott Yocto image. 

Can you tell me wich emmc partition is checked ? mmcblkXbootY  perhaps ?

Hello Vinothkumars,

The "mmc write" performs raw writes to the MMC device. It does not perform write via the filesystem. There is no "write" support to most of the filesystem access commands. Only ext4 seems to have "write" operation. The "mmc write" you performed probably overwrote the MMC partition table.

This is a bug with this version of U-Boot. Or download the one from yocto file, My suggestion is to use a known stable version of the U-Boot bootloader.

Regards
