Introduction

This example demonstrates-

1. How to check SoC latest reset cause.
2. How to check Warm reset cause for R5F Core.
3. How to assert Warm reset for SoC.
4. How to assert Local reset for individually DSP Core.

Use Cases

• Assert Warm reset and check latest reset cause.
• Assert Local reset for DSP core individually.

Supported Combinations

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am273x-evm
Example folder	examples/sdl/reset/reset_mcu/

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)

The above two methods can be used only for building example, but for loading and running, need to follow the below method only.

• Flash the .appimage with qspi bootloader, for refrence see Flash a Hello World example
