Hello, everyone

I meet a problem of VDSP

I made a  Minimum system of BF548.  now I can connect it to VDSP by Emluator and I can access to the DDR, change the value.  It seems that the Hardware is Ok.

 

but when I load a .DXE file ,from the Disassembly window I find the PC point to

IDLE(_unknow_exception_occurred )

untile I change the value of PC register to the main function.  It can run properly .

it seems that the PC pointer  jump over the main function.

 

Even I use the simplest program ( printf(“HELLO WORLD”), as a result, I meet the same problem.

and I change the project option and it doesn't work .

and I sure the LDF file is no problem, all the code are map to L1_CODE.

 

I don’t know what wrong with it , Could someone help me?

Thank you !
