MSP432P401R: microcontroller are blocking

Jorge Luis Bustos Armas

Part Number: MSP432P401R


Some details are being taken with the MSP432P401R microcontroller, since some of our devices that have this microcontroller are blocking (after a while the programming stops executing), even though they have the Watchdog activated and configured so that in case of failure the microcontroller restarts, we hope to see if they could give us support, since as it is not presented in all devices, we have the doubt if it could be our PCB, something in programming or already in itself that the microcontroller is failing, since even charging the program again, it is always presented on the same devices.

    Hello,

    It sounds like you're headed in the right direction. I would encourage you to keep changing your software until it's very basic, such as a simple LED toggle code example from TI Resource Explorer in CCS or at dev.ti.com. Then, if the issue goes away, you can add back portions of your code until it fails. If you're using an external crystal, make sure that's not causing a fault flag that causes the code to hang up.
