Using standard C file I/O functions and C55x cycle accurate simulator

Elias Kokkinis

Hello all,

I am developing a speech processing application and I am fine tuning some parts of the algorithm using specific input data. I am using the standard C file I/O functions and when I load the program to the C5515 ezDSP everything works great. I get the input I want from the I file I choose and I write some output values also.

When I try to load the same program on the C55x cycle accurate simulator (CCS v4.1.3) in order to do have quicker execution times and quicker profiling times I get this error:

TMS320C55x: Error: ERROR : Ensure that you have proper reset vector in your program  NOTE : Reset the target, reload the corrected program and continue execution

and the program does not run.

I have tried excluding the linker file from build and also removing the system initialization functions but I had no luck. Any comments/insight to this problem?
