Part Number: MSP432P401R I am a Lab Director for an ECE department, so I have not worked directly with this LaunchPads. However, I have had two students report similar issues with two LaunchPads. They tell me that, seemingly randomly, both the MSP432P401R and TM4C129 chips on the LaunchPad started getting extremely hot. I was not with the students when they reported this behavior, so I am not sure what preceded it. Certainly one possibility is that they shorted power and ground. I now have the boards in my possession and I have plugged them in to a USB port (in series with a USB current meter), and with no external devices connected to the LaunchPads the MSP432 IC's do indeed get very hot. Both boards are drawing over 600 mA. The TM4C129 is not getting hot on either board. Both boards are rev 2.1. Pressing the reset button on the XDS110 side of the board does not seem to reduce the current draw significantly. All of the on-board jumpers are installed correctly. I noticed several other forum posts describing a similar issue, but that seemed related to the earlier revision of this board (black soldermask) and it seemed related to a voltage regulator IC or a capacitor: https://e2e.ti.com/support/microcontrollers/msp430/f/166/p/490273/1771014#pi316701=1 There is also this post, which describes behavior similar to what I am seeing. However, this is from over two years ago, so I suspect it was also the older, pre-production version of this LaunchPad: https://e2e.ti.com/support/microcontrollers/msp430/f/166/t/453752#pi316701=1 Does anyone have any thoughts beyond the obvious, "Did they tie power to ground?" Has anyone else experienced this issue with the newer, production, red soldermask boards?
