I am using the ISE flow for my EDK project, which has no BRAM instantiated (i.e. the .BMM file created is empty). When implementing the design in ISE, this results in the following error.
Processing BMM file ...
FATAL_ERROR:NgdBuild:Portability/export/Port_Main.h:127:18.104.22.168 - This

WARNING:Data2MEM:53 - File 'edkBmmFile.bmm' was empty or had no content.
For XPS/ISE flow, please remove or rename the system_stub.bmm file in the implementation folder of your XPS project. As a result, the edkBmmFile.bmm won't be created in the ISE project folder and the -bm switch will not be used in NGDBuild.
For Xflow scenario, please consult (Xilinx Solution 23657).
