Error occur when adding custom OPB IP, " must have atleast 1 master assigned!"

Hi everyone,

 

I am using EDK 10.1.03 and trying to add a custom OPB IP to control an Led. After done the steps of creating the IP and configurating address ,port connection and also MPD editing, Hdl editing, I  generated the bitstream but failed, with the following error shown:

 

Can someone give me any suggestions? Thanks in advance!

 

 

Check platform configuration ...

Hi Tarzan,

 

The error message says that there's no master on the OPB bus. OPB needs at least a master on the bus.

 

Where is the OPB bus connected to? Is there a plb2opb bridge? Is your peripheral an OPB master?
