displayport™ 1.4 TX only example design for Cyclone10 GX

Hi, We are currently working on Display port IP in Cyclone 5 GT board and Cyclone 10 GX. We started working on Cyclone 5 GT board. In this we used bitec HSMC board. Loop back example design worked ...

    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.

Thank you Dlim for your support. In our case Cyclone 10 Gx board is our custom board and it has only transmit side. So we couldn't try RX-Tx loop back in the case of Cyclone 10Gx. That is why we tried Cyclone 5 board in order to get an idea how to change Rx-TX design to Tx only design. Is it okay to take Cyclone 10 Gx loopback and modify according to Arria 10?

Also how we can debug this DP using signaltap or any other quartus tool?

Regds,
