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
and add the following layers to conf/bblayers.conf:
BBLAYERS ?= " \
<poky dir>/meta \
<poky dir>/meta-yocto \
<poky dir>/meta-nmrouter \
<poky dir>/meta-telephony \

NB2800:
While the NetModule router is running under the original software you have to do the following steps:
- Find out what boot partition is currently used:
cat /proc/cmdline
- The partition layout is mmcblk0p1 => bootpart0, mmcblk0p2 => bootpart1, mmcblk0p3=> overlay/data partition
- Untar the output of the nmrouter-image build to the partition that is not in use (if the above cmd returns mmcblk0p1 then to mmcblk0p2)
mount /dev/mmcblk0p2 /mnt
rm -rf /mnt/*
tar -xjf ./<image>.tar.bz2 -C /mnt
- reboot the netmodule router
- in u-boot you have to manually overwrite the bootcmd. Use the correct boot partition (bootpart0 => 0:1, bootpart1 => 0:2)
setenv bootcmd 'ext4load mmc 0:2 $kernel_addr /boot/zImage && ext4load mmc 0:2 $fdt_addr /boot/armada-385-nbhw17-nb2800.dtb && setenv bootargs root=/dev/mmcblk0p2 rw rootfstype=ext4 console=ttyS0,115200 rootwait && bootz $kernel_addr - $fdt_addr'
saveenv # save the environment in eeprom (ignore message during bootup)
- boot to Linux:
boot
Do not overwrite the original partition, u-boot will search a valid FPGA there. If you want to overwrite the other partition, make sure you copy the /logic folder from the original partition to the new one!

NB800:
- 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)
