SEGGER Microcontroller J-Trace for Cortex-M3

SEGGER J-Trace for Cortex-M is a JTAG/SWD emulator designed for Cortex-M cores which includes trace (ETM) support. SEGGER J-Trace for Cortex-M3 can also be used as a J-Link and it also supports ARM7/9 cores. Tracing on ARM7/9 targets is not supported. The J-Trace PRO for Cortex-M enables continuous streaming trace via a Gigabit Ethernet interface and lifts the limitations by internal buffers and slow data transmission. The J-Trace PRO allows the recording of infrequent, hard-to-reproduce bugs by capturing complete traces over long periods. SEGGER's J-Trace PRO supports extended trace features, such as code coverage and execution profiling.
