Get the right tools

Once you have an idea of which device is for you it’s time to get started on development and choosing the right hardware and software tools are essential. The Tools & Software tab has a comprehensive list of tools for you to use to develop on the AM335x. The list is a bit daunting so below are the recommendations to get you started.

Hardware

Development Boards

Low cost and full featured platforms to enable developers to explore the full functionality of the AM335x processor. Three platforms are highlighted below.

Get Started Quickly & Inexpensively with BeagleBone Black

BeagleBone Black is the quickest & lowest cost path to AM335x development. At just $45 you can boot Linux in under 10-seconds and get started on development in less than 5 minutes with just a single USB cable.

For more information and to order the BeagleBone Black: http://www.ti.com/tool/beaglebk

To get started on development: http://beagleboard.org/Getting Started

Support Resources: http://beagleboard.org/support

 

Full Featured Development with the AM335x Starter Kit

If you need a full-featured board then the AM335x Starter Kit offers the ability to quickly evaluate most of the features of the processor and accompanying TI components, taking the guess work out of the hardware design and allowing both experienced and novice designers to focus on product differentiation such as advanced graphics and connectivity. For more information and to order: http://www.ti.com/tool/tmdssk3358.

 

Industrial Protocol Support with the Industrial Communications Engine

For industrial communication protocols such as EtherCAT, PROFIBUS, Profinet, Powerlink & Ethernet/IP the Industrial Communications Engine is the optimal platform. The ICE hardware and included software is designed to help integrate the industrial communications interfaces in a broad range of industrial systems. For more information and to order: http://www.ti.com/tool/tmdxice3359.

Reference Designs & Circuits

If your design is similar to the ones listed below then a reference design and/or circuit can aid in your development. TI Designs Reference provides the foundation you need – methodology, testing and design files -- to quickly evaluate and customize a system and, most importantly, accelerate your time to market. For more reference designs and circuits that encompass embedded processors to power management to signal chain go to www.ti.com/tidesigns.

 

Enterprise Tablet

The Enterprise Tablet reference design provides high performance, seamless graphics and the right peripheral support with a bill of materials of less than an estimated $70 at 100Ku. For more information and to order: http://www.ti.com/tool/am335x-tab.

 

EtherCAT Communications Development

Targeted for EtherCAT slave communications, this development platform allows designers to implement real-time EtherCAT communications standards in a broad range of industrial automation equipment. It enables low foot print designs with minimal external components and with best in class low power performance. For more information: http://www.ti.com/tool/tidep0001.

 

PROFIBUS Communications Development

Targeted for PROFIBUS slave communications, this development platform allows designers to implement PROFIBUS communications standards in a broad range of industrial automation equipment. It enables low foot print designs with minimal external components and with best in class low power performance. For more information: http://www.ti.com/tool/tidep0002.

Software

TI provides key runtime software components and documentation to further ease development. The following software components are the ones most widely used.

Software Development Kits with Board Support Packages

Software Development Kits (SDK) for Sitara Processors are royalty-free and come included as part of the development kit. The latest version can also be downloaded on TI.com for free. SDKs include Board Support Packages (BSPs), tools, demos, documentation and more.

 

 

Linux SDK provides developers with an easy set up and quick out-of-box experience that is specific to and highlights the features of Sitara processors. Launching demos, benchmarks and applications is a snap with the included graphical user interface. Developers can also quickly start development of their own applications.

For more information and to download: http://www.ti.com/tool/linuxezsdk-sitara.

 

The Android Operating System offers designers of embedded applications the ability to easily add a high-level OS to their product. The Android system is accelerated with ARM’s Advanced SIMD technology known as Neon, which can be used to enhance many operations such as codecs or graphics pixel manipulations. Sitara ARM Processors include the Neon Advanced SIMD engine.

For more information and to download: http://www.ti.com/tool/androidsdk-sitara.

Integrated Development Environments

Integrated Development Environments (IDEs) provide a software developer a base set of software which allows a programmer to get started writing and testing code. IDEs can include a text editor, software tool chain, and a debugging environment all in a single application that typically runs from a host PC.

 

Code Composer Studio™ is an Eclipse-based IDE developed and supported by TI for TI embedded processor families. The software comprises a suite of tools used to develop and debug embedded applications. It includes compiler, source code editor, project build environment, debugger, profiler, simulators, real-time operating system and many other features. The intuitive IDE provides a single user interface taking you through each step of the application development flow.

Find the right support

You know what processor you want to use, you ordered the hardware tools and downloaded the software tools, now you need to know what support resources are available in case you have any questions.

 

Technical Documents

First and foremost, make sure you have the right technical documents readily available. Technical Documents gives you access to datasheets, errata, technical reference manuals, application notes and more.

 

Training

AM335x-based training includes one-day in-person seminars, multi-day hands-on workshops and online training. Find out which one is best for you:
