Hi
I am working with the kintex-7 mini module plus kit and using ISE 14.1.
I have used a MB core within the ISE project. I am trying to use a extra BRAM and BRAM controller IP cores (apart from default BRAM) of micro-blaze processor. I have connected one port of BRAM to the MB processor through BRAM controller and another port of BRAM are made external to access form HDL module. The design is not working.
The problem comes as soon as I make any port of IPs as external. The existing program running earlier (tested simple LED program) stops working when I add extra BRAM and BRAM controller IP cores and make BRAM ports external. If I leave these ports unconnected, program again starts working.
Not only the BRAM port, any other pins of MB processor causes same problem if assigned as external port. Why it is behaving like this? Is there any issue in using ports as external? Is there any setting for making the ports as external?
Please resolve the issue as soon as possible.
