I am using an 80-pin K30 part with the Flex memory. The project is using the Flex memory to store user preferences. My initial prototype (software development buck) has this function working correctly with out any issues. When I programmed the firmware into another prototype the firmware does not partition the Flex memory. Each time I reset the CPU, the firmware acts as if the part is not partitioned, and writes to the Flex memory fail. Has anyone else seen a problem like this? Any ideas on how I can correct this problem? I am using the IAR tool chain and the Segger J-Trace.
