RGB to DVI TMDS


skaat27

Question

Hi,

I am using the Digilent RGB to DVI IP to output to HDMI, i am using vivado 2016.2 and i havent been able to make the TMDS pin external. When i right click on the IP and choose make external it doesnt do anything. Any suggestions? I know that the IP documentation suggests vivado 2016.4 as tested, but if i use that then i have to use an YOCTO based petalinux which is another headache. I prefer to keep my petalinux dev environment simple.

 

Edit 1 :

i see this warning in the TCL console

No interface ports matched 'get_bd_intf_ports TMDS'

 

Regards,

Karthik

Hi @skaat27,

Here is a forum thread that discusses making a pass through for the pynq board. There is a working hdl project using the RGB2DVI IP core as well as a semi-completed project using just IP cores.  The Vivado portion of the semi-completed project does have the pins made external and constrain correctly as well. 

cheers,

Jon
