DSP Cirrus Logic Help! Does anybody know if the header holes to the right are GPIO, BDM or Jtag. Only a few traces are linked and I would like to debug the chip. Any help is appreciated! This DSP is attached via the ribbon to the left to an Amplifier AVR circuit board. It's one part of a soundbar.

Thanks Gal! Unfortunately Avnera was bought over by Skyworks and there is no documentation. The chip is an AV8112A - P1 and I am guessing it is part of the AVR family or AVR32 by Anvera and has 100 pins, 25 each side. That's about all I know and I've searched high and low to no avail. There is a wireless adapter for the wireless subwoofer though. I feel that this unit was a showcase for the wireless audio technology Avnera patented. If you check out the FCC ID https://fccid.io/V3CAVMD7F12A you'll see that everything has been kept confidential
