Read / Write on the internal flash of the S32K344

[JoDo]

Hello,

I am looking for an example how to write/read the internal flash of the S32K344. I found already an example in the S32DS that uses the Fee and Fls library.

Are there other ways or library (non Autosar) to get access to the NVM peripheral?

Hello JoDo,

There are Autosar level drivers (like FEE, FLS) and non-Autosar drivers (like C40).

There are these examples in the RTD package:

Example_S32K3xx_DS_C40 (in RTD 0.9.0)

C40_Ip_Example_S32K344 (in RTD 1.0.0)

Regards,

Daniel

Hello @danielmartynek ,

thank you very much for the answer. I have tried both ways and they work as they should. Thanks for the hint.

Is there also the possibility to work with an EEPROM emulation or is there a software driver for this?

Regards,

JoDo

Hello @JoDo,

Regarding the emulated EEPROM, it can be done by SW only:

AN13414 S32K1 to S32K3 Migration Guidelines

The FEE driver is in the Autosar high level layer

Daniel
