TMS320F28374S: Code addition and ILLEGAL_ISR

Part Number: TMS320F28374S

Hi, 

When I add code to project that works normally, ITRAP is occurred.

The program counter (PC) points to the ILLEGAL_ISR after stopping debug

I attach a .cmd file and two map files (normal, abnormal)

F28374S_map_cmd.zip

Compiling and downloading of project that is added code are OK,.

I couldn't find difference between normal map and abnormal map. It is only a slight increase used memory size.

How Can I debug it?

Any there are tips and memory allocation rules in linker command file?

Best regards,
