We’re experiencing boot problems on our TX2i solution (using the Spacely carrier from Connect Tech) if we try to run the board headless. I’ve attached a kernel log from the serial port below. It appears to fault when trying to read EDID parameters from the HDMI port. If we connect a monitor to the HDMI port, booting works perfectly.
