 To get an image that is compatible with the NetModule router, build an nmrouter-image. Set the MACHINE in conf/local.conf to 
 MACHINE = "armada-385-nbhw17-nb2800" or
-MACHINE = "am335x-nbhw16" # AKA NB800
+MACHINE = "am335x-nbhw16" # Internal name for NB800 family

     While the NetModule router is running under the original software you have to do the following steps:

         cat /proc/cmdline
-        - The partition layout is mmcblk0p1 => bootpart0, mmcblk0p2 => bootpart1, mmcblk0p3=> overlay/data partition

 NB800:
+Coming from NetModule Software:
+    - Use the same steps as for NB2800 to install a custom rootfs
+    - You don't need to modify the u-boot environment, the NB800 automatically tries to load the correct dtb and the kernel /boot/zImage
+    - There is no FPGA available necessary for the NB800
+
+Coming from an older Yocto image:
     - To update the software you can do a sw-update.sh -l <rootfs.tar.gz>
     - To read and write to the board descriptor use bd read/read-all/write
     - To connect configure the modem and network interface use mmcli and nmcli (ModemManager and NetworkManager)
