We are in need of a specific set of application partitions (APP/rootfs + 4 additional ones, all ext4), in addition we need control over or information of where these are placed on the emmc. We are populating the root filesystem with a custom linux tree (not L4T) and kernel. We’ve successfully manage to get everything to run correctly by modifying create-jetson-nano-sd-card-image.sh to generate an sdcard-image with our partitions but it is not obvious how to make the same partition table changes to a production module and flash them.
Currently we’re investigating using a modified board-config and partition_table xml, but it is unclear if this is the preferred way to go.
Cloning, as described here: Jetson/TX1 Cloning - eLinux.org - only seems to modify the (single) APP partition and leaves no apparent way to modify the partition table.
What is the recommended way to achieve this?
