doesn't boot, no video

[evilbunny]

Thanks for your quick reply. I bought 2 new power supplies, both rated at 5V/3A. I've tried the board against 3 different (old) monitors. Two of those require an HDMI to DVI cable; the other is a pretty old TV that's at least got an HDMI port. I'm seeing the same results in every case. The LEDs light up on the board, but there's no video signal. Maybe I just need a newer monitor?

For my DVI monitor I had to add the following:

Code:

drm_kms_helper.edid_firmware=edid/1920x1080.bin

To the end of the kernel append line, otherwise it was more miss than hit with auto detection.
