MSP430F2618: Flash code area is experiencing rare, unexpected erasures and modifications

Part Number: MSP430F2618


Tool/software:


We are using the MSP430F2618 chip for a microcontrol system. After power-on initialization, the system reads data from InfoB and InfoD as operational parameters. Once the system stabilizes, these segments are erased and rewritten for use in the next power cycle.

Currently, we are encountering an issue where the Flash code area is experiencing rare, unexpected erasures and modifications. We would like to consult: What possible scenarios could cause such abnormal Flash erasures or modifications?

  • Hi,

    One possible reason for Flash unexpected modification may be the voltage supply unstable. You could check whether your supply is stable.

    Is this issue happened all the time, and will it also happen in your other board with the same FW?
