Suhas, There are a few ways: 1. On GPP-side, use trace to see what's happening. http://tiexpressdsp.com/wiki/index.php?title=Enabling_trace_in_DSPLink Here, since you know MSGQ_locate is stuck, that likely won't help. Is MSGQ_locate hung such that it exits with Ctrl C (i.e. pending on a semaphore)? Then it means that the Message Queue was not created on the DSP. This can happen if the MSGQ_locate calls are going to the other processor so fast that the other side is always in the ISR responding to the 'is this MSGQ created' questions. So it's important to have a small delay between subsequent MSGQ_locate calls in the loop.
2. Use JTAG for debugging the DSP-side: http://wiki.davincidsp.com/index.php?title=Debugging_the_DSP_side_of_a_DSPLink_application_on_OMAP_using_CCS http://wiki.davincidsp.com/index.php?title=Debugging_the_DSP_side_of_a_CE_application_on_DaVinci_using_CCS 3. Use Notify for debugging DSP-side: http://tiexpressdsp.com/wiki/index.php?title=Debugging_DSP_side_using_DSPLink_NOTIFY_module BTW, message sample should work out-of-box, so have you changed something?

I am trying to get the message.out sample application running, so as to understand the flow of DSP Link. Presently I am stuck at point where, ARM side application tries to locate the DSPMSGQ. I want to debug this thing further. How can I get the DSP side traces ? I want to debug the DSP side code. Can XDS510 Jtag emulator be used to get the DSP side traces? If yes, then how do I use this? Can anyone please tell me how to make use of this?
