SPD demo question

Pusoy — Tue, 19 Dec 2023 10:00:11 GMT

In the main.c file of the demo provided by the S32K3 Safety Peripheral Drivers version 1.0.3 Design : Product Download : Files (flexnetoperations.com), I noticed that the first highlighted area clears the reset flags. Doesn't that mean the BIST section will never be executed?
1. Is this a design flaw or do users need to manually modify certain code?

Hello,

yes the highlighted code (Mcu_GetResetReason function) clears the reset flags but the function will also store the reset reason into a global variable for later use. So then when the Mcu_GetResetReason() is called for a second time it will still return the correct reset reason remembered in a global variable of Mcu driver.

Best Regards,
