Hi everyone,

I'm working on modifying u-boot source code for testing HDMI function on PandaBoard (CPU is TI OMAP4430). There seems no related information on the web.

I've studied the android kernel source, and it confused me that the linux video driver access lots of registers which are not mentioned in the OMAP4430 Technical Reference Manual.

However, the driver of android is so huge and complicated that I can't port it on u-boot.

Can anyone tell me how to control HDMI module inside OMAP4430 by u-boot? I just want to do some tiny tasks, such as showing the Android logo or filling the screen of specified color.

Maybe give some suggestions or directions for me to study is OK.

Or is it impossible? and why?

Thanks a lot.
