MSP432 VCORE Voltage Going Down To Zero



Hi,

In one of our custom designed board we are using MSP432P401R. For analog power supply part of the chip, we are using same circuit and components as mentioned in datasheet and used on EVM.

The problem we are facing is, we are not able to program MSP, after debugging we found that Vcore voltage which should be 1.2V after resetting the device goes down to zero. If you again press reset it will come back to 1.2V but within a minute it again goes down to zero.

Please suggest something.
