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

AM243X-EVM

Parameter	Value
CPU + OS	r5fss0-0 nortos
	m4fss0-0 nortos
Toolchain	ti-arm-clang
Board	am243x-evm
Example folder	examples/drivers/gpio/gpio_led_blink/

AM243X-LP

Parameter	Value
CPU + OS	r5fss0-0 nortos
Toolchain	ti-arm-clang
Board	am243x-lp
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

AM243X-EVM

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

AM243X-LP

• Watch out for LED LD1 on the LP to blink which is controlled by GPIO0_22.
