Clone and restore i.MX 6DualLite mmc on board

[Pete_104636]

Hi ,

we have NXP i.MX 6DualLite products running on linux, and we have quite a lot of dependencies installed on top of the linux running python to complete an embedded system. The question now is that installing those dependencies is a hit or miss with lots of trial and error, and we have quite a lot of devices that need to be provided to our end customer. Therefore we are thinking of the option to clone the linux system of other unconfigured devices with one "golden" device that has all libraries installed correctly. Is there a way to put the i.MX 6DualLite into a peripheral mode to clone and restore the whole mmc resided on the board ? 

In addition, how would one be able to change the bootup sequence so that we can use a usbdrive loaded with clonezilla ?

thanks

Pete

maybe you can refer to the document as below:

Hi Joan, I assume you are implying that clone cannot be done, but only install packages customized can be prepared for our purpose ? thanks

according to your previous questions, I though you need install your own packages based on yocto, but you don't want to customized yocto because of too many dependencies, so I send the link about how to install the packages in yocto, if you just want to mount your own rootfile system, you can use uuu tools, which is very useful tools to download images to the board, more detailed information you can refer to the enclosed file

You can check the following document page 5.

ums in uboot can let your board become a sdcard reader.

Another way  is to boot and mount rootfs on  sdcard or usb stick if you have sdcard slot or usb on your board, then use dd command to dump the mmc as mirror file.

thanks Smithcoba for providing a lot of useful information.

I forgot one thing.

If your board has ethernet design on board, you can use mount nfs rootfs, then dump the mmc/emmc as a mirror files. 

If your board has usb port on board, you can use usb disk as rootfs.Or use usb ethernet gargde and use nfs rootfs.But this way is too compliated, I personally not recommand.
