S32K3 FEE_Read problem

xingyun — Mon, 29 Dec 2025 08:53:46 GMT

The S32K3 implements FEE. However, FEE_Read always fails and its return valueRetVal is 1.Do not use the following "else" statement:

When reaching the "Fee_ExampleAssert" point, it is impossible to exit the while loop directly. May I ask what the problem is? Below is the EB configuration:

memory:

Hope the passing engineers could take a look and offer some help.

Thank you very much.

Hi@xingyun

Please tell me what RTD version you are currently using and what demo you are referencing, and what modifications you have made.

Thank you very much for your reply. I have carefully checked it and found that it was a problem with the underlying configuration. I found that the Fee Block Size and the Fee Virtual Page Size need to be in a multiple relationship for the operation to succeed.

For FEE here, is there any other question you can help me with? The reference I used is SW32K3_RTD_R21-11_3.0.0_P07 - Fee_TS_T40D34M30I0R0 (S32K344)

At present, before the FEE configuration and debugging were carried out, there was no problem with the ADC sampling. However, after adding the FEE module, when the initialization, triggering and interrupt functions of the ADC are commented out, the FEE storage is normal. However, once the ADC is turned on, a situation where it gets stuck at Adc_StartGroupConversion and then enters a hard fault occurs.
Then I attempted to comment out all the relevant content of FEE and only focused on the ADC part. However, I found that there was a problem with the ADC's trigger for sampling, and it entered a hard fault when it reached the Adc_StartGroupConversion stage.
