Hi experts :

Because our customer board do not have SD slot, emmc boot only!

we may need to replace u-boot image or *.dtbo in linux.

but we can not mount boot partition,

our device :

root@j7-evm:~# ls -l /dev/mmcblk0*
brw-rw---- 1 root disk 179,  0 Nov 19 18:09 /dev/mmcblk0
brw-rw---- 1 root disk 179, 32 Nov 19 18:09 /dev/mmcblk0boot0
brw-rw---- 1 root disk 179, 64 Nov 19 18:09 /dev/mmcblk0boot1
brw-rw---- 1 root disk 179,  1 Nov 19 18:09 /dev/mmcblk0p1
crw------- 1 root root 240,  0 Nov 19 18:09 /dev/mmcblk0rpmb

mount error message as below :
