Custom Arria10 gx board with ad9361

Hi Prince_Punia ,

You had some contradictory statements in this thread, which made the situation unclear for me.

In order for me to understand what you're doing and what's your question, please answer the following questions from my side:

1. Which exactly is the custom board that you're mentioning?
2. What project did you take as starting point?
3. What changes have you done to the reference project?
4. Can you share your changes publicly? This would help us help you and understand what you're trying to do.

Also, please note that we will be out of office until Tuesday, so our responses will be delayed.

Best regards,
Iulia

Hi,

1. I am using custom board with A10 FPGA

2)  Reference Design Used: fmcomms2_a10soc_bring_back

3) Instead of HPS, I am using NIOS-II Softcore processor, that I included in Qsys file

4) Can you share some email, to which I can share the design?

Regards

Prince

Apologies for the late reply.

We've discussed this internally, and since we don't have a working example for this, we can't really offer support for this use case. That branch is an old one and we stopped developing for this since we didn't find a solution to work at maximum lane rate.

Hi,

Thanks for the information.

Can you suggest anything regarding the issue? Any direction towards which we can move forward?

Any reason why this was not working at maximum lane rate?

Hello Prince,

The reasons we removed the project is stated fmcomms2: a10soc remove project by acostina · Pull Request #541 · analogdevicesinc/hdl (github.com) 

The fmcomms2 pinout is not compatible with the Arria 10 SOC FMC pinout in the sense that we cannot respect the recommendation for the source synchronous interfaces for Arria 10. The same applies for Arria 10 GX. In theory, for a custom board you can respect the recommendation, but given we haven't worked on a design to the point of validating it in hardware, nor do we have alternative designs that are similar, we cannot give you more detailed information on how to move forward.

Hi,

I understand. 

Thanks for the reply.
