I want to create a factory image from my board. The board only have emmc. I use mfgtool to burn image to emmc.And now i want to get image from /dev/mmcblk1p1.
Now i'm writing the image to u-disk via usb-otg. But the system is running while i use 'dd' command to get image from /dev/mmcblk1p1.If some files changes while creating images, the images will go wrong.
So can i use mfgtool get image from board? Or just mount emmc to pc as a disk via usb-otg?
