Hi NKRIS7,

I remember you open one thread which is --> https://forums.intel.com/s/question/0D50P00004OyVC3/hi-i-am-working-with-de10nano-board-to-access-external-ddr3-fpgatohps-sdram-interface-axi3-is-not-working-properlyaxiawready-is-always-low . It seems to be similar issue where you are facing problem on the waitrequest signal.

May i have your confirmation whether this is the similar issue? If yes, then may I suggest to continue the conversation in previous thread ?

Thank you for your kind understanding. 😊

Regards,
