S32K312+FS26 watchdog refresh

[Akhil1]

Hello,

I am working on S32K312 to do SBC FS26 watchdog refresh every 50 ms. I am facing the issue with the InitDevice function, while Initializing the SBC.

Can anyone help me out?

Hello Akhil1,

I hope all is great with you. Thank you for using the NXP communities.

As we know, after power up, wake up from Standby or RSTB assertion, the fail-safe state machine is moving through several states and wait in Init_FS state. In this state, the RSTB pin is released to high level and the MCU must configure FS_I_xxx registers and then perform a good watchdog refresh within 256 ms.

Do you mean that you are not able to perform the first good watchdog refresh?

I hope this information helps.

Regards,

David
