Debugging ARM and DSP

std
Intellectual 710 points 
Hi TI,


Am I right to say that emulator is set up to single-step either ARM code or DSP code ?



Can emulator be used to single-step from ARM code into DSP code ?

In Linux SDK, ARM will call function to run on DSP.



If there is issue between ARM and DSP, how do you debug it ?




Thanks,


Mr Tan

    Mr. Tan,
    

    Yes, the emulator can single-step either ARM or DSP code.
    

    There is no mechanism to single-step from ARM code into DSP code. When the Cortex A8 signals to the DSP to do an operation, the Cortex A8 continues executing code itself at the same time the DSP C674x starts executing something new.
    

    Our intention is to provide you with the SYSLINK tool which will properly start the DSP running. If that is working correctly, then your debug effort can concentrate on the pointers and memory contents that are loaded on the DSP.
