I was thinking about designing a small VGA daughter board but have decided to write a driver for the HDMI chip on my dev board.  

It is connected to the same pins as the LCD connector.  So can I ask.  If I fire up the LCD example and then initialise the hdmi chip I should get an output?

Probably not. I dare say hdmi would want specific timing which mighht not be the same as a lcd module. I dare say the answer is in the linux drivers.

Anything that has things like HDMI is almost bound to be "Linux class" and there'll be a Linux port / BSP for it. So for "reference drivers" just look at what's happening in the kernel source for the board.

What "LCD example" ?

 

Top Tips:

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
