S32K344 Fee using internal flash?

[ola_gook]

I am evaluating whether S32K344 is able to emulate FEE using internal flash.

The S32DS FEE example uses external flash via QSPI only.

My company is considering using different MCUs for different purposes, but all will need some kind of NVM like FEE.

Thus, since S32K312 does not have QSPI, I can only assume that it also does not support FEE?

Correct?

Otherwize please point me to an example of using FEE based on internal FLS setup.

Regards.

Hi @ola_gook 
Can you let me know which NXP SW product version you're working on S32K344

@ola_gook ,
S32K344 allows to use internal flash for Fee. As User manual of Fls module in Release RTD AUTOSAR Ver 1.0.0:

So, it's possible to use FEE with internal Flash.

For Fee example for S32K3, you can update your S32DS SW to latest version, which is installed S32K3XX development package and S32K3 RTD Autosar 4.4 includes:

Then you can find Fee example for S32K344 and S32K312 included

Please note that select Fls channel is FLS Hardware channel is 'FLS_CH_INTERN' to use internal flash config

Later, in configuration of FEE module, select the corresponding Fls sector defined previously in Fls

Thanks for the response.

So then I suppose S32K312 also has the internal flash FEE feature?

(What puzzled me was the fact that there was an external flash driver defined at the end. I didn't pay enough attention to the FLS_CH_INTERN pointer.)

Yes, It's correct. Because FEE refer to Fls HW config, which is allowed internal flash. In this case both S32K344 and S32K312 can refer Fls Internal flash setup
