I followed the (thankfully very detailed) installation instructions on the Wiki. (Thanks for the great docs.) Installing OpenWRT on SD was super easy… Installing it on eMMC was easy enough (other than needing to dust off a Windows machine) but didn’t work! It rebooted like it said it would in the docs, but it’s not listening on 192.168.100.1, and there are no activity lights on the LEDs when I reboot. I can reboot with the SD card installed, and it will boot, but booting off of eMMC is going to be way more reliable, and I don’t want to get the whole configuration set up and then have to redo it once I get eMMC working.
What can I do to diagnose what’s wrong? Re-flashing it is quite a pain with the ancient windows machine, but it just being DOA with Ubuntu on it is kind of sad. 
Let me know how to get this working to spec!
Super cool box. I just wish it came in a 5gbps version too!
Thanks!
