S32K3 hardfault whilst calling logf function

[HemantK]

Hello All,

I am facing a wierd issue while using logf in S32k3 SOC.
For the below code:

1. float logIndex = 1.2f;
2. static float testLog;
3. testLog = logf(1.2f);
4. testLog = logf(logIndex);

Executing step 3 works fine but as soon as processor tries to execute step 4, I get hard fault.

Can you please suggest what the potential cause could be?

Hi @HemantK,

What IDE / compiler / library do you use?

Thanks,

Hello @HemantK,

Thank you for the information.

I'm not able to replicate the issue on my side.

Can you share a test project with this error?

Regadrs,

Hello, 

I found the issue with the project. Our project is cmake and was using a different library as compared to the one used by S32DS.

Many thanks for the help
