J-Trace Cortex M


J-Trace for Cortex-M

JTAG emulator with trace support for Cortex-M cores

J-Trace for Cortex-M is a JTAG emulator designed for Cortex-M cores which includes trace (ETM) support. J-Trace for Cortex-M can also be used as a J-Link and it also supports ARM7/9 cores. Tracing on ARM7/9 targets is not supported.
