Q: Do the DHCOM modules have a serial numbers included? If yes, how is it accessible?
A: The serial number of a DHCOM module is stored inside the bootloader environment. It can be retrieved by u-boot commands like printenv or by Linux commands like “fw_printenv”.


Q: We would like to use ubifs for rootfilesystem.
A: Ubifs is the standard NAND flash file system (FFS) for DHCOM.


Q: We have the need for additional UBI volumens (partitions).
A: It shouldn't be necessary to make changes in u-boot, Linux kernel or devicetree.


Q: We want to backup the root filesystem from the NAND-Flash of the target.
A: You can use the DHCOM Update Mechanism of root filesystem of the bootloader for the rootfs in the backup mode. Further information at: DHCOM Update: Linux Root Filesystem
