FlexNVM/FlexRAM Example? (AN4282)

[lsrbigfoot]

I am looking to implement AN4282 (Enhanced EEPROM Functionality) on a Kinetis K22 micro using the KSDK drivers (fsl_flash.h & fsl_flash.c). Are there any AN4282 related code examples available? Where can I find them?

Hi,

Customer could visit MCUXpresso SDK to build&download SDK package for [FRDM-KE15Z] board.

There provides [flexnvm_eeprom] demo for customer reference with below path:

..\FRDM-KE15Z\boards\frdmke15z\driver_examples\flash\flexnvm_eeprom

Wish it helps.

Have a great day,
Mike

Thanks! This helped. The frdmke15z driver files (fsl_flash and other pieces [like fsl_ftfx_controller and fsl_ftfx_nvmem]) appear to be a different implementation when compared with MK22F512A's driver files (large fsl_flash driver).

How compatible are frdmke15z's_flash related driver files with the current MK22F512A and its fsl_features?

Hi,

KE15 FlexNVM working as EEPROM flash commands is same with MK22FX512A.

Customer could refer and using related driver for MK22FX512A.

The only difference is the FlexNVM and FlexRAM memory size:

KE15:

FlexNVM = 32KB & FlexRAM = 2KB  sector size is 2KB;

MK22FX512A:

FlexNVM = 128KB & FlexRAM = 4KB  sector size is 4KB;

Wish it helps.

Have a great day,
Mike
