Hey,
I’ve a new X20 board, connected HDMI, keyboard, mouse and 12V/2.25A power supply. Set jumper to AUTO BOOT SET and USB HOST SET (HDMI SEL is off). No microSD card inserted. So far, everything according to the Getting Started guide.
But nothing is happening. There is no output from HDMI. No LEDs are flashing. Yet, the board is getting warm, so I think it is doing something.
Any ideas what could be the issue?
