J-Trace PRO for Cortex-M is setting a new standard for trace probes. It enables continuous streaming trace via its SuperSpeed USB3.0 and Gigabit Ethernet interface, lifting the limitations by internal buffers and slow data transmission. 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.
