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.
Supported Combinations
- Attention
- A53 NORTOS, A53 FREERTOS and A53 FREERTOS SMP support is experimental and is NOT supported by TI.

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
- Watch out for LED LD26 on the EVM to blink which is controlled by MCU_GPIO0_5.
