SpletStep 3: Use SWO Trace The LPC54018 device offers serial-wire output trace (SWO) that enables useful debugging features in µVision. The picture shows the setup dialog for the SWO trace. The PC Sampling on Data R/W Sample option allows us to get PC samples for each read/write instruction. In our case, for each read/write access to the SpletTrace SWO output in non-debug mode I've successfully configured the SWO trace output and read the prints in STM32CUBE IDE -> SWV ITM Data Console. I see these prints are working in debug mode. Do STM32 chip (ARM Core) prints the same in non-debug mode (application mode)? If yes, how to do it?

As pointed out below: it is not possible to use SWO with OpenSDA because the OpenSDA firmware does not support SWO. The hardware (debug connector) would support it, but … SpletThe I-jet Trace for Arm Cortex-M is equipped with a SuperSpeed USB 3.0 interface reaching 5 Gbps in data transfer from the probe to the C-SPY Debugger. The probe is available in 64 Mbyte or 256 Mbyte to match different needs of trace memory size. The trace data collection can be done with 1,2 and 4-bit with 150MHz ETM trace clock and 64-bit ...

Splet02. jun. 2024 · This information can be read over the TRACE pins of your MCU if you have a trace-enabled debugger (e.g. a J-Trace or a Lauterbach TRACE32), alternatively it can be streamed over the SWO pin of your SWD bus. While more pins allow for more data to be read, much can be done with the single SWO pin without requiring complex tools. http://trace32.com/wiki/index.php/SWO

SpletETM trace is supported in Parallel trace mode only, while both parallel and Serial trace modes support the ITM trace. For details on how to use the trace capabilities, see the debug documentation of your IDE. TPIU's dedicated trace pins are multiplexed with GPIOs. SWO and TRACEDATA[0] use the same GPIO. Trace is limited to dedicated pins.
