TIRSLK-EVM: Have a problem with the baseboard

Part Number: TIRSLK-EVM

The bottom plate is connected with the MSP432. The indicator light of the single chip microcomputer is not bright after it is plugged in, but the indicator light of the single chip microcomputer power supply will be bright after it is removed. There is no problem with the microcontroller. So there's a problem with the bottom plate.
