Release Notes

Overview

The Software Development Kit (SDK) for Profinet allows you to quickly integrate Profinet functionality into your device. The SDK is supported for Sitara processors by Texas Instruments Incorporated and currently available for AM64x, AM243x and AM261x series of Cortex®-R5 based devices.

This document collection contains a Quickstart Guide and the API Reference Manual for the Profinet SDK.
