Er, it's now working. Why? Not sure. I had to try out a new SD card (Samsung with larger capacity, 32GB, as my Sandisk 32GB cards weren't working), so I recreated my rootfs, created the disk image, dd to sd card, booted, scp the NM system-configurations config file from VBox system to target board, restarted NM (not sure if I had too or not), and ifconfig shows me an assigned IP address :) So, not sure what the heck is going on, but maybe my running system was out of whack and just needed a reboot. I was installing some packages directly on the target with aptitude. Hopefully it's reliable and stable so that the IP connections always comes up on boot, and stays up. Fingers crossed :) Brendan.
