Reset Isolation - MCU Domain
Introduction
The example demonstrates the MCU reset isolation in the use case when the MCU domain is running a safety application.
The example can be run in OSPI boot mode. On running the application the MCU R5 and logs a heartbeat message to theMCU UART.
On pressing the SOC Warm reset button (SW6), the MCU R5 which is reset isolated will keep on running, and the Main domain will undergo a warm reset. On reset the SBL would not reload the MCU R5 core again.

Steps
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,
