Other Parts Discussed in Thread: ENERGYTRACE

MCU:MSP432.I debuggered the example project code“pcm_power_state_change”，Energ trace+ did not generate any data,when application was running.how to deal with it..

the start and stop of Energ trace+ is ok.

Instructions for using EnergyTrace++ are provided in Chapter 7 of the Code Composer Studio 6.1 for MSP432 User's Guide (SLAU575): www.ti.com/.../slau575d.pdf

Are you using a LaunchPad (red or black) or a custom-built board?

Launch Pad is black，and I just followed the chapter 7 of the SLAU575d.pdf at first.But energy trace+ did not record data.

I am not able to replicate your issue using my MSP-EXP432P401R black LaunchPad, CCS v6.1.3, and EnergyTrace v4.1.0. Is data collected in EnergyTrace mode?

From CCS Installation Details，I find CCS is v6.1.3，Energy Trace is 4.1.0.
And whatever mode(trace or trace+) I use,it does not work.
Can you try the example code of"pcm_power_state_change"and save the picture of energy trace+ .I wanna have look it.

As requested, after a 10-second timer:

I found that energy trace prompted"Target current exceeded the maximum current(75ma).."as the picture.

I think it is the reason resulted the energy trace failure.But i don't know how to fix it.

Are any additional devices, board, or peripherals connected to the MSP-EXP432P401R? Otherwise it would seem that the DC-DC converter on your XDS110-ET is defective and causing either inaccurate current readings or excessive current to be supplied to the target device. Are any components on the board getting noticeably warm to the touch? Please consider upgrading to the new MSP432 LaunchPad (red board) which comes with post-release silicon and an updated XDS110-ET design/layout.

Ryan

I exchanged another MSP432LaunchPad（black）and removed all additional devices,board,or peripherals.And then retried the test，energy trace+ was running ok with recorded data.
I think your estimation that the DC-DC converter on XDS110-ET is defective make sense.
thank you for your support.
