So I've attempted to follow the links from R-Pi Troubleshooting. I can't discern a pattern. I see a solid green, short off, long solid green. Then intermediate green flashing for hours, it feels like a successful boot happened.
Here is a video of the Start up. I'm not sure what is happening after ~30 seconds the green light shuts off and will just randomly blink on/off which shouldn't that just be signally SD card activity?
I don't get an output to HDMI even after modifying the config.txt to include
hdmi_force_hotplug=1 nothing changed.
I plugged in a standard USB keyboard a on boot tried pressing 1/2/3/4 to change the display mode and none-produce an output. Immediately after plugging in the USB my Display does reset it's
NO DEVICE FOUND error and switch to a black screen before reverting back to
NO DEVICE FOUND.
I re-formatted the card using SD Card formatter. Then re-imaged the SD card using Win32Disk Imager (from sourceforge). Now I get this pattern. Still confused.
The image I'm working off of is 2016-05-25-raspbian-jessie.zip, I've verfied my SHA1 sum with the download so I'm confident it isn't corrupt. I'm using a SAN Disk Ultra SD card (which is on the list of tested cards and is marked Green) so I believe my SD card is fine.
