Introduction

The following shows an example of SDL RTI API usage by the application to set up the RTI as a watchdog and usage of the various APIs. Events can be monitored by enabling the events in the associated ESM instance.

Use Cases

Use Case	Description
UC-1	WINDOWSIZE_100_PERCENT
UC-2	WINDOWSIZE_50_PERCENT
UC-3	Latency/Propagation timing error(early)(50% window)
UC-4	Latency/Propagation timing error(late)(50% window)

Supported Combinations

Parameter	Value
CPU + OS	m4fss0-0 nortos
	r5ss0-0 nortos
Toolchain	ti-arm-clang
Board	am64x-evm
Example folder	examples/sdl/rti/uc1/
Example folder	examples/sdl/rti/uc2/
Example folder	examples/sdl/rti/uc3/
Example folder	examples/sdl/rti/uc4/

Steps to Run the Example

• When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
• When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
• Launch a CCS debug session and run the executable, see CCS Launch, Load and Run
