MSP430F449: flash corruption?

Part Number: MSP430F449


I am trying to resolve an issue I've been seeing on an MSP430F449 used in a product Ihave in the field. The product has times where higher ESD could happened, and sometimes the instrument (using MSP430F449) loses its program and no longer functions correctly.


Once I re-load the hex file to the MSP430F449 then the instrument will back return to normal, so I believe this shows that the flash been corrupted.


Let me know if this is an issue you’re familiar with and if there is any additional information you need from us to help with this!
