Module 3: Hardware peripherals

 

Attention: the Quickstart Guide for BSP 2.8, based on the Ångström distribution, is not being updated anymore. Depending on your SoM, you have different options:

Vybrid and Tegra: the information is provided as-is and still accurate, since newer Toradex BSPs are not ported to those SoMs. Just keep in mind that the Guides are not being maintained anymore, even if we find bugs or outdated instructions.

Apalis TK1 (all variants), Colibri iMX6ULL (all variants), Colibri iMX7S 256MB and Colibri iMX7D 512MB: these computer on modules are still regularly maintained in our BSPs and, to get started, you must check the software page Toradex BSP Layers and Reference Images for Yocto Project. Since Torizon is not supported, at the moment a Quickstart Guide is not available.

All other i.MX-based SoMs: you have two options to get started with embedded Linux: the first is to follow the Quickstart Guide for Torizon, which provides the greatest out-of-the-box experience, or if you choose to use Yocto, check the software page Toradex BSP Layers and Reference Images for Yocto Project.

Overview

In this module, you will go through the process of accessing hardware peripherals typically employed by our customers in their projects. Although some peripherals/interfaces are not described in the module, it provides an overview of how to access some of the hardware abstracted by the Linux operating system.

After you finish it, you will be able to: understand how to choose and toggle a GPIO pin.

Contents

In order to include all of the topics presented in the introduction, this module is divided in the following sections:

Basic GPIO usage - Colibri Evaluation Board - Colibri iMX6ULL

Basic UART usage - Colibri Evaluation Board - Colibri iMX6ULL
