Colibri iMX7 full NAND image

Is there any way to make full copy of NAND in Colibri iMX7 ???
I create custom kernel, u-boot and linux config and I would like to make backup/copy to other colibri module all those. Is there a way to do that without manually upgrading-patching original module??

While this is not recommended as already discussed at various places throughout this forum (e.g. here) one may do so using the mtd-utils resp. mtd-utils-ubifs while booted from external media. It may also be possible to do part of this using U-Boot’s dfu, nand or ubi commands.
