CCS/TMS320C6415: Multiple DSP sync problem

Matthew Wong
Prodigy 150 points
Part Number: TMS320C6415

Tool/software: Code Composer Studio

Code Composer Studio Parallel Debug Manager seems to have a bug when attempting to run simulations (.out files) on multiple DSPs simultaneously. We are using CCS version 3.3 with the Spectrum digital Emulator, model number XDS510PP Plus. I need to know if there is a workaround for this issue. We need to run simulations on multiple DSPs - The simulation must run simultaneously on each DSP in order for the them to communicate with each other. When clicking the "Run" button in the Parallel Debug Manager the DSPs will run momentarily and then halt. However, when starting each of the DSP's individually, they run continuously but don't stop when they should. Is this a hardware or software issue? If software, what typically causes this?

    This is a tough one, with the root cause being potentially in a variety of places. You are using an unsupported version of CCS (v3.3) and an unsupported debug probe (XDS510PP). One thing you may want to try is to use an updated version of CCS. The XDS510PP can be used in version of CCS up to CCSv8.3.1 (It is NOT supported in CCSv9.x). If you still have issues with the later CCS versions, it will be easier to support you. You can load the same *.out files that were built using CCSv3.3.

    Note that multi-core debugging works quite differently in these later CCS versions: http://software-dl.ti.com/ccs/esd/documents/ccs_multi-core-debug.html

    Thanks
