Energy Tracing

Nayeon Kim

I'm working on WIndows 7 64-bit, ccs Ver 6.1.2, MSP432P40LR launch pad.

I set the breakpoints on debugging mode so that I could trace energy for certain block(function).However it seems it's not working.

I'm wondering if energy tracing is possible on debugging mode with breakpoints.

Also, want to know if I can trace energy for certain function(ex.main) rather than setting certain time.

Working on CCS is my first time and I'm lost. Pleas help me out.

Hello,

Only is standard 'Run' mode (run target with debug control)

http://processors.wiki.ti.com/index.php/Energy_Trace_for_MSP432?keyMatch=energytrace&tisearch=Search-EN#How_does_it_work.3F

However, that is often not the best scenario for energy measurements because of the reasons mentioned in the above link.

If you are using the recommended 'Free Run' (or 'Run Free') mode, breakpoints will be ignored when the target is run in that mode.

Yes, you can get a rough percentage breakdown per function in ET+ mode:

There is also more documentation in Chapter 7 of this User's Guide:

Hope this helps

Thank you for replying.

According to given link, processors.wiki.ti.com/.../Energy_Trace_for_MSP432 shows energy percentage of each function(ex.main,func4,func6..) consumed during certain time(30s).However, it doesn't meet what I want to know exactly.

I wonder if it is possible to set number of function runninng times(ex. func4 2 times,func6 6 times) and then trace energy rather than just setting certain tracing time(ex.5s,30s).If I don't set function running time, I have no idea of the ending point after I traced energy for certain time(30s). However, I need the energy for running certain function(ex. func4 func5) for my project.

Unfortunately the exact functionality you are looking for is not yet supported. Sorry
