8.2i EDK - Error: "This application has discovered an exceptional condition..." received during Performing Clock DRCs


I receive an obscure error message from EDK8.2. No other eror messages proceed it, so I am not sure what the source of the problem is. The error message is as follows: 


"Performing Clock DRCs... 


This application has discovered an exceptional condition from which it cannot recover. 

make: *** [implementation/apache_ppc_core.bmm] Error 1 




If this happens during "Performing Clock DRCs...", and you are using DRC bus on a PPC target, it could be caused by the unconnected DCR clock port "CPMDCRCLK" on PPC. It is a bug that you cannot see it in System Assembly View. It is fixed in EDK9.1. 


To solve the problem before EDK9.1, please add this port manually in the MHS file. For instance: 


PORT CPMDCRCLK = sys_clk_s 


For more information about "CPMDCRCLK" port, please refer to "External DCR Bus Interface" in ppc405block_ref_guide.pdf.
