J-TRACE, JTAG+Trace for ARM-Cortex-M

J-Trace

 

Segger J-Trace for ARM Cortex-M0/3/4/7 is a high speed hardware trace probe developed from ground-up for ARM Cortex-M ; it connects via USB to the PC host running Windows. Segger J-Trace integrates seamlessly into IAR Embedded Workbench and is fully plug-and-play compatible, and in addition very easy to use.

 

Segger J-Trace combines an embedded trace macrocell (ETM) with an embedded in circuit emulator (ICE) macrocell to deliver all the real-time debug functions of a traditional emulator. It has a 16MB buffer memory. No special hardware is required to substitute for the real microprocessor functions in order to make them visible.
