AM335x SYSBIOS Industrial SDK 01.00.00.08 Release Notes



May 2, 2013

Introduction

The SYSBIOS-based software development kit (SDK) for industrial communications is designed for the Sitara AM335x ARM Cortex-A8 microprocessor family to enable customers add real-time industrial communications easily and quickly to their system. By making all the basic system software components immediately available, the Kit allows developers to focus on their application code, where they can add the most differentiation. Optimized to support real-time industrial communications protocols such as EtherCAT, Profibus, Profinet, Ethernet/IP and many others, the SDK includes a real-time, low-footprint SYSBIOS kernel with boot loader and sample industrial applications to get started quickly.
