CCS/MSP432P401R: Flash Programmer: Reading device TLV failed.

Part Number: MSP432P401R

Tool/software: Code Composer Studio

Dear team,

I'm using MSP-EXP432P401R launch pad.

Firstly, it works well. But after I refer to "boostxl_edumkii_accelerometer_msp432p401r" demo and use "MAP_CS_setDCOCenteredFrequency(CS_DCO_FREQUENCY_48);" to set frequency to 48MHz, the board doesn't work.

Error is like following:

Can you tell me what happened? How can I fix this problem?

Since my 3 launch pads all failed, I appreciate if you can help me soon.

Thanks.

Kenneth
