I am trying to use the HDMI port as an output on the TX2 in much the same way as an HDMI port is used on a camera, just video.
I have USB3 cameras plugged into the TX2, I process the frames, convert them to HDMI compatible format and then want to send them to the HDMI port - I have an HDMI video TX connected to the HDMI port of the TX2, which transmits the images to an RX which in turn is plugged into an HDMI monitor (the device is an amimon connex). I have also taken the connex out of the loop and simply plugged in a Blackmagic screen, into the TX2 HDMI port, and still nothing…?
I have disabled X (so now I don’t I see the entire Linux desktop, just text), disabled virtual consoles (SSH/debug console are active) too.
Have tried writing to /dev/fb0, tried using fbi justo to test but nothing etc etc etc
Has anybody got any ideas how to do this or do I have to do something different for the TX2?
