Program once field

Hi at all,


I have got a question to the program once field at the MK10DX128VLH7 cpu.


First of all I have to say, that I'm using the normal flash and eeprom functions without any problems.

Now I would like to use the program once option to store a serial number in my device.



Here are my questions:


1.      Which addresses do I have to choose for the program once field? These ones?

2.     Will the program once field be erased when I repartition the device? (I know that you should

partition your device only once)


Well, if the addresses above are right I have programmed the right sector. If I write to this sector with the

WRITE_ONCE_COMMAND I can store data and read out the data. But if I restart the device in debug mode,

the cpu gets a reset when reading the sector and I haven't got any chance to ckeck the error registers.


Thanks a lot!
