This layer depends on:

URI: git://git.yoctoproject.org/poky
branch: jethro
revision: HEAD


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" and add this layer to conf/bblayers.conf

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!
