I have not been able to get my device to boot and have tried seemingly everything to get it to work. As far as I can tell, my unit should be using the 7010 files and no hdmi. I have burned the sd card 5 times using my linux machine and a windows machine with 2 different sd cards and it still won't boot. I have even tried using the hdmi kernel even though my unit doesn't have hdmi. I have looked in the rootfs partition of the sd card, but the log files don't seem to be getting written to. The log files that are present must be from the original unit that the image was made from. If I delete the log files, they never get re-created.
When I look at my router, I never see the MAC address of my unit. The 2 green leds light up and the ethernet lights both light up and blink. I don't have a serial cable to look at the boot output. I suspect something is failing very early in the boot process, since nothing is written to disk. This has been very frustrating as I have successfully done this same process with 3 other similar devices (rasp pi, banana pi) and I've never had a problem with the device not booting. That is why I felt confident getting the headless unit, as I would just ssh into it, but obviously that is not possible since it never gets an IP address. Hopefully someone can help, otherwise I guess I''ll see if I can get another unit (but I really don't think it is a hardware problem). Any ideas? Thanks.
