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

Supported Combinations

Parameter	Value
CPU + OS	mcu-r5fss0-0 nortos
	wkup-r5fss0-0 freertos
Toolchain	ti-arm-clang
Board	am62px-sk
Example folder	examples/drivers/gpio/gpio_led_blink/

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.
