What is the difference between flash_ftfl and flash_ftfe?

1、In mqx bsp path :C:\Freescale\Freescale_MQX_4_1\mqx\source\bsp, some boards（eg: twrk60d100m, twrk60n512） have flash_ftfl.c, some have flash_ftfe.c(eg: twrkf120m), what is difference between these device?

2、We want to used FlexRAM as high-endurance EEPROM, Whether MK60FX512VLQ15 has this feature? if not, which type of mcu has this feature? and where there is example？

Hi www

Generally speaking, FTFL exists in Kinetis K series < 120 MHZ product, FTFE existed in Kinetis K series > 100 Mhz product..

FTFE and FTFL are the same on function.

For a specific case, take K60d100 for example, it calls flash_ftfl.c , for frdmk64f, it calls flash_ftfe.c.

So it depends on which type of chip you are using.

for MK60FX512VLQ15, the "x" means there is a flexnvm in MCU parts, yes, it has flexRAM in it.

The example for your reference is

C:\Freescale\Freescale_MQX_4_2\mqx\examples\flexnvm

Have a great day,
