we are using ADSP-SC589 with Lauterbach debugger and EmbeddedArtists 10pos-to-20pos ARM JTAG adapter.

We found, if Pin 9 on 10pos connector is connected to GND, CPU always stays in reset. We cut GND from pin 9 and connect it to TRST pin 3 on 20pos ARM JTAG. With this trick we able to debug ARM core with Lauterbach Trace32.

Hope it helps.
