My MSP432 is drawing 170 mA. Why?

Other Parts Discussed in Thread: ENERGYTRACE, MSPWARE

Hi.

I got MSP432 launchpad a week ago.

Studying MSP430 LaunchPad Workshop Course Workbook as my textbook. There was no problem whatsoever. But in lab 7(Energy trace) I've encountered a problem.

After flashing solution of lab_07b_lpm_timer project. I ran EnergyTrace. But EnergyTrace immediately stops and it says "Target current exceeded with the maximum current (75mA) supported by EnergyTrace."

Huh?

So I actually measured current and voltage with my multimeters and the uc was drawing 170 mA. Even in the reset state.

No external circuitry has ever connected to my launchpad. Even no single jumper wire.

What could be a cause of this problem? ESD?

Planning to get another MSP432 LaunchPad and MSP432P401RIPZ(LQFP100) next week.

I will update this post after replacing MSP432 chip on this LaunchPad board.

Thanks to everyone who cared about my problem.

Replaced old MSP432 with the new one. It turns out that the MSP432 was the problem. After replacing, current consumption of the board drop to 1.5 uA, with debugger connected and all default jumpers connected. Very happy with it.
