    Hi,


    I found out below AN doc that may provide answer to you.


    It's still referring to A10 DisplayPort Tx only Example Design but C10 GX DisplayPort design should be quick close to it as well

    • Pls go through the AN doc in detail to learn about DisplayPort Tx only example design
    • Chapter 1.4.4 - tell you on some debug feature
    • Chapter 1.5 - teach you how to convert DP Rx to Tx example design to become DP Tx only example design


    Since you are using custom board then it's very hard to isolate whether the failure is on board issue or Quartus design issue

    • If you have Cyclone 10 Gx dev kit + Bitec DisplayPort daughter card then it will be easier to isolate out board issue


    Thanks.

Hi Dlim,

Thank you for your reply. The document you shared helped usto debug C5 issue. Now Tx only system working in C5. In that we didnt made BITEC_EDID_800X600_AUDIO = 0. So our output always supported 800x600 resolution as maximum one! Is this parameter affect video too?

Hope this knowledge will help us to implement Tx only system in C10.
