Introduction

This example uses the WDT module in non reset mode to generate NMI Interrupt.

• The Watchdog interrupt is configured as a non-maskable interrupt and the user-defined callback function is registered.
• ESM module is configured with ESM Group 2 number and ESM NMI number to generate a non-maskable interrupt to the CPU.
• The callback function in the application handles the watchdog interrupt

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
	a53ss0-0 nortos
Toolchain	ti-arm-clang
	arm.gnu.aarch64-none
Board	am64x-evm
Example folder	examples/drivers/watchdog/watchdog_interrupt/

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
• Please select the UART port used for console as mentioned in Setup UART Terminal
