If I can get video out of it, I am about convinced that the only micro-hdmi adapter I have is a $16 dud I got from Wallmart. Banggood says 2 more adapters and the big, whole top heat sink won't be here till around the 3rd. So if this doesn't work, I'll just shelve it till then. Maybe forever, I'm about burned out on this. I've written several cards, without ever seeing a single byte of video on a monitor that works fine when driven by a pi-3b. 2 possible differences. Its not powered correctly when powered from gpio pin 6=gnd, and 2=5.11 volts. A pi3b has been running that way for 2+ years and the gpio is said to be 100% pi3b compatible. Argue with me on that, this rp-4 came with no docs. I do not have a psu with an OTG connector. Or this $16 wallmart adapter is duff. Does anyone have some typical scope waveforms pix that would show what a working hdmi socket has for signals? Now its morning locally, time go see about some caffiene for me and the missus.
