About create image from emmc using mfgtool/usb-otg

cyndent — Wed, 16 Jan 2019 10:59:19 GMT

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?

Hi Mingyang

for emmc programming one can follow Linux Guide from nxp linux documentation:

https://www.nxp.com/webapp/Download?colCode=L4.14.78_1.0.0_LINUX_DOCS&appType=license&location=null

or tutorial from

Programming eMMC on i.MX6 - Boundary Devices
