I am using the TWR-K64F (specific chip = MK64FN1M0VMD12). This chip is listed as having no FlexNVM. As I understand it, the FlexNVM is necessary to use the FlexRAM (of which this chip has 4 kB) as EEPROM. Does the lack of FlexNVM mean that the FlexRAM on this chip is unusable as EEPROM? Or simply that there will be no EEPROM backup? And what does that imply for the write endurance of the FlexRAM?
Furthermore, are there any code examples that demonstrate use of the FlexRAM on the K64F? I have the Kinetis SDK 2.3.0, but this does not include any examples showcase the FlexRAM, and the only driver I can find is fsl_flash, which looks like it is for interacting with the program flash.
