Software funcional reset and FCCU functional duration (FS26 enabled)

FabioG — Tue, 04 Jun 2024 14:59:42 GMT

Hi there,

On some tests seem that after a software reset (2ms of duration on RESET_b pin) the consecutive reboot happens 92 ms later (all GPIO in 3-state and no software running).

Executing a fault injection on a FCCU channel configured as "short reset", this time grows to more than 250 ms and FS26 triggers an unwanted destructive reset.

Why FCCU soft reset is so long?

where I Find these s32k reboot times, i don't find them in DS or RM.

Best Regards,

Fabio
