Profiling with IAR EW

Started by zjeriet December 21, 2009
Hi guys,

I need to do some optimisation on a piece of code and wanted to try out the profiling functionality of EW. Now I activated it like in the manual. This means:
- C/C++ Compiler: Output>Generate debug information
- Linker: Format>Debug information for C-SPY
- Debugger: Plugins>Profiling

I can now start and stop the profiler by its on/off button.
But when I start my application it either says:

WITHOUT SOFTWARE BREAKPOINTS:
Mon Dec 21 17:00:32 2009: Profiler: No cycle counter could be found. Profiler will only count function calls.
Mon Dec 21 17:00:33 2009: Failed to set hardware breakpoint. All available resources are already in use.
Mon Dec 21 17:00:33 2009: Virtual breakpoints can be enabled in Options dialog under Debugger->FET Debugger->Breakpoints
Mon Dec 21 17:00:33 2009: Profiler: Could not set enough breakpoints.
WITH SOFTWARE BREAKPOINTS:
Mon Dec 21 17:11:36 2009: Profiler: No cycle counter could be found. Profiler will only count function calls.
Mon Dec 21 17:11:36 2009: Virtual breakpoint is used. This will force single stepping on 'Go'.
Mon Dec 21 17:11:39 2009: Profiler activated
Mon Dec 21 17:11:45 2009: Performance warning: Use of virtual breakpoints forces singlestepping.
Mon Dec 21 17:11:45 2009: Performance warning: Use of virtual breakpoints forces singlestepping.

Any of you guys have seen similar issues?

Thanks

Zjeriet,
You just posted two groups of messages, but no 'issue' to be solved. All I can say is that the Enabling/Disabling of software breakpoints is in accordance with the difference between both groups of messages.
What's the problem?

Hey Michael,

Sorry about not being completly clear on the problem

I'm not able to get the profiling info as my app can't run or can't run normally due to the described scenarios.
I'm running an RTOS and this might complicate the matter.
EW is also popping up a message:
Profiler: No cycle counter could be found. Profiler will only count function calls.

But even that info is not available.

Greets,
