GPIO LED Blink
Introduction
This example configures a GPIO pin connected to an LED on the EVM in output mode. The application toggles the LED on/off for 10 seconds and exits.
To modify the example to use main domain GPIO, refer Accessing main and wakeup domain peripherals from MCU domain

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
Attention
As the wake-up R5 is the device manager, it needs to be started by the SBL. So it can not be loaded through CCS. It should be flashed and booted through SBL.
Refer Flash a Hello World example for flashing the application.
