Has anyone seen and solved a Flexmemory partitioning failure?

Good evening,

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.

Thanks

Hi Stephen

Have you check that there is not hardware issues on the board?

Can you load a simple project on the device? this is to check that you can program properly the device.

I hope this will you.

Good afternoon Pedro,

I was able to fix the problem. I was initially specifying an incorrect partition size.
