DDR3 Avalon slave wait request stays high in the middle of a write

Honored Contributor II

Hi all, 


I am trying to write to a DDR3 memory slave using an avalon interface (Cyclone V GT dev kit). I am using the avalon burst master templates provided by Altera ( I am continually writing the data in a loop using the write burst master. However, after few complete transfers, the wait request signal from the slave stays high in the middle of a transfer and the transfer stalls indefinitely. I have tapped to the length variable from the master template and I can infer that the write stalls in the middle of a transfer due to the wait request signal.  


Can anyone advise me why this behaviour, please? 



Kind regards,
