Hi Samson,

Please accept my apology for not follow-up sooner.

Do you have a chance to try out the reference design given and compare the signals with your custom design? If yes, can you share with me the results seen? Is the waitrequest issue replicate-able with reference design ?

Regarding the code, i really wish I could help but unfortunately, I'm not the expert on the coding area. But, I will try my best to help you. Allow me sometime to consult my colleague that have this expertise. I'll get back to you later regarding this.

Thanks

Regards,

Aida

Hello Aida ,

I downloaded the reference design , and I looked at the code of the reference design.

It involves NIOS II soft core , it differs from what we do , we simply use the PHY Lite in our logic.

Our R&D team have been stuck on this issue for a while ,

could you please help us to contact the PHY Lite code expert to take a look on our PHY Lite connection ?

Thank you so much for your support.

Regards ,

Samson
