Once all the jumpers on the EVM are properly located, follow the steps below:

  • Remove jumper from J3 - IOVDD_MB on AC-MB.
  • Remove SEL5 jumper regardless if using HW or SW mode. (This jumper prevents proper boost functionality).
  • Connect AC-MB to EVM by placing the EVM on top of the edge of the AC-MB.
  • Connect 5V power adapter to barrel jack J21 on TAS2320EVM.
  • Connect USB cable from PC to AC-MB.
  • Place back the J3 - IOVDD_MB jumper on AC-MB to either 3.3V or 1.8V.

At this moment, the device is powered up and running, ready to play audio. The evaluation kit works as any other sound card, select the EVM as system playback device and use any software like web browser, media player, and so forth.
