DSPLink module: How to debug msg transfer between ARM and DSP

Hi Oded,

I am not familiar with Codebench, but one way to inspect the memory on the DSP (or view the output to any printf calls) is to connect to it via JTAG using CCS. Here are some articles that describe how to do so depending on your target platform:

If your platform does not match any of the above, you should still be able to do something similar to load symbols and connect to the target board, once you have your JTAG connection set up. 

If you do not have JTAG, you can also use this technique for debugging purposes:

Hi Vincent,

Is there an option to debug simultaneously ARM and DSP?

Because i know that i can debug seperate ARM with co desourcey and DSP with codecomposer, but i need to do it  simultaneously.

Thanks, Oded.
