Mr. Pelle in response to your question we are developing a number of different wireless audio devices. The cc8520 should work for wireless audio in some applications. One application will require that the transmitter broadcast to a large number of receivers without pairing.
We have built our own boards but are unable to connect using the CC Debugger and the purepath configurator. It shows that the device is disconnected. Attached are scope prints of the signals at the JTAG connector.
I have also included a copy of CC8520 section of the schematic. Only the 8520, regulators and jtag are connected.
Looking at your scope grabs I see one thing I think is a bit strange :
Why is the SCK and CSN lines floating at about 1V before and after the CC debugger is trying to connect ?
Would seem to me that the 8520 is not getting the power it should.
From what I see in your schematic you should cut the line to pin number 9 on the JTAG connector and add IOVDD power to pin 2 of the same connector if it's not connected there now.
