Trace start- and stop breakpoints with ETM
Technical Note 14806
7/6/2016 11:07 AM
Trace start/stop breakpoints are only for ETM/ETB trace. Not for SWO trace.
Probe vs ETM/ETB
Trace start/stop breakpoints can be used with:
- I-jet-Trace if the target CPU supports ETM or ETB trace.
- I-jet if the target CPU supports ETB trace.
- J-Trace if the target CPU supports ETM or ETB trace.
- J-Link if the target CPU supports ETB trace.
- CMSIS-DAP if the target CPU supports ETB trace.
As of IAR Embedded Workbench for ARM version 6.60, there is a misleading error message "User error: Breakpoint type is only available when using J-Trace". It really means that you do not have any of the combinations (3) or (4). The error message has been improved in releases newer than version 6.60.
