s32k312 flash

fengba_360 — Wed, 11 Sep 2024 08:37:36 GMT

Hello, I'm currently using the mem_43_INFLS driver to operate the flash on the s32k312. I have a few points I'd like to consult about:

1. Can I use this driver to erase the pflash under boot mode so that I can update the app program?

2. Can I use this driver to operate the Dflash to simulate EEPROM? If so, are there any corresponding example routines for reference? Thank you!

Hello @fengba_360,

1. Yes

2. For the SW emulated EEPROM, there is the RTD FEE driver.

Regards,

Daniel

What's the difference between FEE and Mem_43_INFLS? I'm quite confused. Could you please guide me further? I have two requirements: one is to erase and write app programs during boot, and the other is to simulate EEPROM under the app.

As I said, FLS is for programming / erasing the flash, FEE is used to emulate the EEPROM.

Refer to the User Manual and Integration Manual of the drivers that can be found in the installation directory of the RTD.

Or have a look at Autosar documentation:
