SEGGER J-Trace Pro Cortex-M

J-Trace PRO for Cortex-M is setting a new standard for trace probes. It enables continuous streaming trace, lifting the limitations by internal buffers and slow data transmission to give you all the insights you need to develop and optimize your code.

J-Trace PRO can capture complete traces over long periods—thereby enabling the recording of infrequent, hard-to-reproduce bugs. This is particularly helpful when the program flow ‘runs off the rails’ and stops in a fault state.

It also supports extended trace features, such as code coverage (so engineers have visibility over which parts of the application code have been executed) and execution profiling (providing visibility as to which instructions have been executed and how often—so hotspots can be addressed and optimization opportunities identified).

J-Trace provides a JTAG/SWD+Trace connector. This connector is a 19-pin connector. It connects to the target via a 1-1 cable. The following table lists the J-Link / J-Trace SWD pinout.

 SignalTypeDescription
Pin 1SignalVTrefTypeInputDescription This is the target reference voltage. It is used to check if the target has power, to create the logic-level reference for the input comparators and to control the output logic levels to the target. It is normally fed from Vdd of the target board and must not have a series resistor.
Pin 2SignalSWDIO/ TMSTypeI/O / outputDescriptionJTAG mode set input of target CPU. This pin should be pulled up on the target. Typically connected to TMS of the target CPU.
Pin 4SignalSWCLK/TCKTypeOutputDescriptionJTAG clock signal to target CPU. It is recommended that this pin is pulled to a defined state of the target board. Typically connected to TCK of the target CPU.
Pin 6SignalSWO / TDOType InputDescription JTAG data output from target CPU. Typically connected to TDO of the target CPU.
---Signal---Type---DescriptionThis pin (normally pin 7) is not existent on the 19-pin JTAG/SWD and Trace connector.
Pin 8SignalTDIType OutputDescriptionJTAG data input of target CPU.- It is recommended that this pin is pulled to a defined state on the target board. Typically connected to TDI of the target CPU.
Pin 9SignalNCTypeNCDescriptionNot connected inside J-Link. Leave open on target hardware.
Pin 10SignalnRESETTypeI/ODescriptionTarget CPU reset signal. Typically connected to the RESET pin of the target CPU, which is typically called "nRST", "nRESET" or "RESET".
Pin 12SignalTRACECLKTypeInputDescriptionInput trace clock. Trace clock = 1/2 CPU clock.
Pin 14Signal TRACEDATA[0]TypeInputDescriptionInput Trace data pin 0.
Pin 16Signal TRACEDATA[1]TypeInputDescriptionInput Trace data pin 1.
Pin 18Signal TRACEDATA[2]TypeInputDescriptionInput Trace data pin 2.
Pin 20Signal TRACEDATA[3]TypeInputDescriptionInput Trace data pin 3.
