Arm Cortex Texas Instruments CC2650: SWO pin configuration

28-May-2025

CC265xx devices support configuring the DIO pin on which the Serial Wire Output (SWO) trace is output.


Possible solution

1. SWO output must be connected to the TDO pin of the Arm adapter.

2. Select cJTAG Debug Protocol in Hardware | CPU Options | SoC.

Since the JTAG protocol uses TDO for debug communication, SWO can only be captured when the cJTAG Debug Protocol.


3. Go to Hardware | CPU Options | SoC Advanced and specify which IO port to use for SWO.
