Initialization address is not 0xFF80

Hi, I am a  beginner of DSP.I design a test board of TMS320VC5409,but there is something wrong with my board.When I startup CCS,then click "GEL",choose "C5409_configuration" and "CPU_Reset" next. But the Initialization address is not 0xFF80, is 0xFF8B.My CCS version is 2.2,and the emulator is XDS510,Loaded GEL file is c5409.gel,MP/MC pin switch to "1".When the Initialization address is 0xFF8B,*.out file load failure every time.I change MP/MC pin to "0",the Initialization address is 0xFF81.still load *.out file failure.What should I handle this situation? Maybe there are some misconnection in hardware?
