Overview

This is the 2/3 chapter of the Getting Started with IGEP SMARC iMX6 Tutorial Guide.

In this second chapter, we will learn some basics tasks. Upon completion, you will be ready to continue with chapter 3/3 that explains more advanced tasks.

What can I do

You must logged in the board.

Handle the GPIO-LEDS

The board has two user bicolor (green/red) leds available that can be controlled. In its simplest form, you can control of LEDs from userspace. LEDs appear in /sys/class/leds/ and you can turn on and off with following commands:

$ echo 1 > /sys/class/leds/igep\:red\:led1/brightness $ echo 1 > /sys/class/leds/igep\:red\:led0/brightness $ echo 0 > /sys/class/leds/igep\:red\:led1/brightness $ echo 0 > /sys/class/leds/igep\:red\:led0/brightness

$ echo 1 > /sys/class/leds/igep\:green\:led1/brightness $ echo 1 > /sys/class/leds/igep\:green\:led0/brightness $ echo 0 > /sys/class/leds/igep\:green\:led1/brightness $ echo 0 > /sys/class/leds/igep\:green\:led0/brightness

How to use UART (RS485)

This How-To is meant to be a starting point for people to learn to use RS-485 port on IGEP devices as quickly and easily as possible. We use IGEP YOCTO Firmware and RS485 example which describe how to setup and write data on the RS-485 port.
