I am using a Freescale K60DN512 and MQX4.1 .
I need to store some data on NVM memory. I followed the example flash_demo.c and it works fine.
The problem is on the re-flash the program (for example for an update of FW) which erase also my previous data stored into NVM memory.
Is there a way to preserve my NVM data after a reload of FLASH memory or I have to find another way (extern EEPROM bye I2C bus for example)? Thanks all,
