DE2-70 + TRDB-LTM Out-of-syn Problem

Hi all, I have a DE2-70 + TRDB-LTM, DE2-70 + touch LCD screen from terasic. I can display image on the screen, both at 800x480 and 400x240. However, occasionally, when I power-on-reset the entire system, the image color is not correct. After studying a little, I suspect the touch LCD screen is out of sync with Nios II. 

 

Do you if my conclusion is correct / or something else is mal-functioning? Thanks alot.

Hey. 

I also work with TRDB LTM in DE2. I wanted to ask you if you can share with me the VHDL code. 

I'd appreciate it.

Altera UP IP suite comes with a demo project LTM "Extras_DE2_LTM" 

Port it to DE2-70, then you will see the issue 

 

It can be, device problem, board problem, or cable problem? 

 

I do not see the problem in DE2 though!
