5.7. RTI Safety Example¶
5.7.1. Introduction¶
This example displays setting up RTI to
Setup of Windowed Watchdog Timer (WWDT)
Handling WWDT failure interrupts received on the ESM module in the MCU domain R5F
5.7.2. Use Cases¶
Use Case
Failure n
RTI Inst
ESM
Window
Input Trigger
Expected Event
UC-1
Permanent Failure (100% Window)
RTI0
MCU_ESM0
100%
Stop servicing completely
Window End
UC-2
Permanent Failure (50% Window)
RTI0
MCU_ESM0
50%
Stop servicing completely
Window End
UC-3
Latency / Propagation timing error (early) (50% window)
RTI0
MCU_ESM0
50%
Service before window opens again after previous feeding
Window Start
UC-4
Latency / Propagation timing error (late) (50% window)
RTI0
MCU_ESM0
50%
Service after full window has passed since previous feeding
Window End, then Window Start
5.7.3. Example Details¶
The example should be loaded to the hardware using the Secondary Boot Loader (SBL) from the SDK.
