MSP430F5528: FIlesystem causing issue while copying or deleting the data

Part Number:MSP430F5528

Hello,

I am using some memory of the flash as a filesystem and storing some data in file system to use it in run time. Following are the cases which are erasing or corrupting the flashed firmware and I need to flash the firmware again.

1. when I delete the file from the filesystem (happen sometimes).
2. when I copy the more data in filesystem then its size allocated (happen always).

Please provide solution to prevent this situation for above cases.

Regards,

Rohit
