I need a way to DD an image directly to the hard disk. Is there a way to build an “mmc.img” with all the partitions present?
Is there a reason you can’t use the nvidia flashing tool?
I want to boot into an initramfs kernel on the device to perform an in-the-field update. Therefore, I can’t use the 32bit tools that nvidia provides.
I am going to try to look at flash.sh, and attempt to create my own image using parted on a sparse/raw image file.

Some good information is written about this for the JTK1. The actual flash clone commands on a JTX1 are required and different from the commands for JTK1, but the whole concept of partition tables and cloning is the same. So for information in general:
