1.3.9 J-Trace for Cortex-M
J-Trace for Cortex-M is a JTAG/SWD emulator designed for Cor-
tex-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.
1.3.9.1 Additional features
• Has all the J-Link functionality
• Supports tracing on Cortex-M targets
• Comes with built-in licenses for: Unlimited number of
breakpoints in flash (FlashBP), J-Link GDBServer, J-Link
RDI, J-Link RDDI and J-Flash (production programming
software).
