Creating HDMI TX only (no Nios) solution targeting Cyclone 10 GX Dev Kit

[Evan44]

I am looking to create a simple HDMI TX demonstration of sending a fixed RGB video pattern to a sink monitor while targeting the Cyclone 10 GX development kit. 

I don't want to use Nios, and it appears that the Intel HDMI reference designs all feature the Nios. So presumably I need to piece together a system from scratch, but don't want to spend any time re-creating anything that has already been done.

I understand that one methodology is to start off with Platform Designer,  and then add and configure IP such as the Clocked Video Output (CVO) and Test Pattern Generator (TPG) cores. 

But are there any other pieces I need to add in order to complete this "simple Tx demo" architecture, especially with regard to targeting this development kit?

The HDMI reference designs took care of so much of the housekeeping, but again they were Nios driven. 

Thank you for any assistance.

Hi Evan44,

Thank you for reaching out.

Apologize for the delayed response as we encounter some technical difficulty.

Just to let you know that Intel has received your support request and currently we are confirming the details with our internal team.

I shall come back to you with findings.

Thank you for your patience.

Hi Evan44,

Thank you for your patience.

Regarding to your question, yes you are correct, to implement a TX only design you need to add TPG and CVO into the design.

At the moment, all our HDMI design example uses NIOS for flow control. 

If you wish to design TX only without NIOS, you need to implement the C function into the RTL code.

You may locate the C code in designfile/software/tx_control_src/.

Hope this answers your question.

Thank you.
