Hello,


I hope you are doing well.


The DDR IP instance will be reflected by the IP setting.

You have set the Local Maximum Burst Count = 64.

Then the local_size width will be 6.


But the memory burst length is set to 8 beats and you are running the controller with a half rate.

So your local_size should be 2.
