Introduction

This example demonstrates High and Low priority events received from the MCU_ESM through the application-registered callback. It also shows routing and clearing of events to the MCU_SAFETY_ERRORn pin.

This example displays setting up ESM to

* Enable/Disable input events to the ESM module for each ESM instance
* Registration of application callback for ESM error events for each ESM instance
* Designating input events as high priority or low priority for each ESM instance
* Designating direct pin routing to MCU_SAFETY_ERRORn pin for external monitor communication

Use Cases

Use Case	Description
UC-0	Configuration of High Priority ESM
UC-1	Configuration of Config Priority ESM
UC-2	Configuration of Low Priority ESM

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am275x-evm
Example folder	examples/sdl/esm/mcu_esm0/

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

Sample Output

Shown below is a sample output when the application is run,

ESM Example Application
 
TIMER_ESM_init: Init MCU ESM complete
 
ESM example init complete
