J-Trace
J-Trace PRO is an advanced debug probe that supports the advanced tracing features of Arm Cortex cores. It can capture complete instruction traces over long periods of time—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. Using the right software tools, J-Trace PRO trace probes are particularly helpful in analyzing system behaviour enabling uninstrumented live code coverage and code profiling.
