Hi @f-nelson,

This is because S32_SCB->AIRCR is not implemented on S32K3. The following are the functional reset sources supported by S32K3

You can generate a SW reset through the POWER driver instead. Please refer to this community post: S32K344 How to manually trigger one Function Reset - NXP Community.

Best regards,
Julián
