Firmware may still need to enable the SWO output pin - as this part of the setup is microcontroller dependant. Decoding ETM data over the SWO pin is not currently supported. Live graphing of decoded ITM data. Support for Custom ITM Data Decoders: ...
SWO Decoding - "console" text output and binary data (signed and unsigned 32-bit integers, Q16.16 fixed point integers, single percision floating point values) The registers that are part of the DWT, TPIU, and ITM debug components will automatically be configured and do not need to be set...
but with the Cortex-M family, ARM introduced the Serial Wire Debug (SWD) Interface. SWD is designed to reduce the pin count required for debug from the 5 used by JTAG (including GND) down to 3. In addition, one of the pins freed up by this can be used for the low cost SWO tracin...

(SWD) Interface. SWD is designed to reduce the pin count required for debug from the 5 used by JTAG (including GND) down to 3. In addition, one of the pins freed up by this can be used for the low cost SWO tracing technology - for more details see the FAQ "Overview of Trace ...
In the command line I can get SWO working: My target has a CPU frequency of 170MHz. Start openocd: openocd -f "interface/stlink.cfg" -f "target/stm32g4x.cfg" -c "transport select hla_swd" -c "tpiu config internal - uart off 170000000" -c...
SWO configuration: SWO was a hit and miss as multi-core devices appeared and device manufacturers were not using the default base addresses for the ARM debug hardware like TPIU, DWT, ITM, etc. We factored this out in a user settable gdb script as well a small TCL file for OpenOCD which...
swoConfig .sourcestringBothSource for SWO data. Can either be "probe" to get directly from debug probe, or a serial port device to use a serial port external to the debug probe. swoConfig .swoEncodingstringBothBMP only: SWO encoding data used at the line level. Depends on the probe hard...
When I try to enable SWO console output with pyOCD, I don't get any output. My configurations looks like this: "swoConfig": { "enabled": true, "cpuFrequency": 32000000, "swoFrequency": 2000000, "source": "probe", "decoders": [ { "type": ...
