Hi There,
I have a system equipped by FS26 SBC and FCCU configured on a S32k344-based system.
FCCU NCF lines are configured as short reset function and EOUT signalling to FS26 for global recovery, so a fault triggered to a NCF lines performs a funcional reset and FS26's fail-stafe state machine (in normal mode) asserts FS0B. isn't it (MFS2621AMDABAD)?
My problem is to manage SW faults, out of FCCU NCF domain that I need to perform a global safety reset (FS0B asserted ). My Idea is to avoid a MCU-driven reset and use A SW_NCF FCCU trigger:
for example ,instead of using a MCU-driven reset, I call:
eMcem_AssertSWFault(EMCEM_DCM_NCF_7_SW_NCF_0)
so: (1)EMCEM_DCM_NCF_7_SW_NCF_0 triggers a FCCU short reset with a EOUT signalling to FS26 and a consequent FS0B assertion. Is it the right way?
Another (2) Hypothesis was to send an SPI command to FS26 directly for ASSERT FS0B and perform a MCU-driven reset, but It seem to me to have a lot of drawbacks.....
Is the first mode (1) Ok or (2) or do you suggest some other mechanisms?
Best Regards
Fabio
