Tool/software: TI C/C++ Compiler
I have been using the PADK - Professional Audio Development Kit, to achieve active noise control for some time now. It is a multiple channel I/O incorporating the TMS 320C 6727 DSP.
However, Im just getting some problems with the ADC input channels. Normally, i connect the output of an electret microphone directly to one of the ADC input channels and the input signals are processed by the DSP. But now as i connect the output of the microphone to the ADC channel (anyone of them is the same), the voltage at the microphone output (sane as that of the ADC input channel) freezes and the mic no longer works. I have been doing a lot of tests to find out where the issue is. and I think that the problem lies with the ADC input channel. But I am unable to trouble shoot it and if necessary to reset the ADC input channels.
Is anyone aware of that issue? and any solution to that.

Does this mean you solved your original problem? If so, please post something about the resolution for future readers of your thread.
I did a search on TI.com for "debugging jtag connection problems" (no quotes) and found the Wiki article Debugging JTAG Connectivity Problems legacy.
Please read through that for some ideas and pointers to debugging your problem. The main thing I can think of is to try the Test Connection button in the View Target Configuration editor window in CCS. That usually responds back with some good information that can help point you to the problem. You may need to use some circuit testing to find if there is a signal break somewhere in your JTAG pod or cable or on the board. And make sure your emulation drivers are updated to the latest.
Thanks for your reply.
In fact, i havent been able to solve the original problem exactly. Placing a blocking capacitor at the input of the ADC does solve partly the problem.
I'll try to find out the connection problem of the JTAG. but I would like to know if ever i would like to have the board checked, which company is offering service maintenance on the PADK.
I have made to understand that Lyrtech is closed but i dont know which company has taken over.
