Re: WARNING: No source level debug

["Gao, Liming" <liming.gao@intel.com>]

Please check the debuglib instance. 

MdeModulePkg.dsc sets DebugLib|MdePkg/Library/UefiDebugLibConOut/UefiDebugLibConOut.inf. This library instance prints the debug message to Console. 
Nt32.dsc sets DebugLib|MdeModulePkg/Library/PeiDxeDebugLibReportStatusCode/PeiDxeDebugLibReportStatusCode.inf. This library instance prints the debug message to StatusCode. The StatusCode service prints the debug message into the different StatusCode handlers. NT32 has its WinNtOemHookStatusCodeHandler. So, you can see the message log. 

Thanks
Liming
