SEGGER's 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 Live Code Coverage (so engineers have visibility over which parts of the application code have been executed) and Live Code Profiling (providing visibility as to which instructions have been executed and how often, so hotspots can be addressed and optimization opportunities identified).

The J-Trace PRO Cortex-A/R/M provides support for Cortex-A/R/M-based microcontrollers. The SuperSpeed USB 3.0 interface of J-Trace PRO enables continuous streaming trace via USB with the full trace clock. Streaming in real time allows for data capture over long periods of time because there is no limit set on the amount of trace data. This gives you all the insight you need to develop and optimize your code.
