Question: What is the maximum number of DSPs the XDS510 can debug/drive at the same time ?

Answer: There are two issues:

1. XDS510 board driving capability

Theoretically you can debug any number of DSPs with the XDS510 for our JTAG-based devices (C5x, C4x ...). However the XDS510 board can drive between 16-32 processors without buffering. Remember, debugging multiple-DSPs require the OS/2 or SUN version of the C source debugger. The windows version does not support multiprocessing at this point. Multiprocessor debuggers for TI DSPs can be obtained from third parties (White Mountain, DSP Research, ..)

2. Parallel debugger Manager (PDM) limitation

PDM under OS/2 is able to open a maximum of 82 (approx.) processors. This limitation comes from the operating system used (an OS typically has a max. number of windows that it can open). This combined with the fact that PDM always opens a window for each processor causes the limitation. The Sun version has a similar limitation.
