2.1. Release Notes

2.1.1. Overview

The Processor Software Development Kit (Processor SDK) is a unified software platform for TI embedded processors providing easy setup and fast out-of-the-box access to benchmarks and demos. All releases of Processor SDK are consistent across TI’s broad portfolio, allowing developers to seamlessly reuse and develop software across devices. Developing a scalable platform solutions has never been easier than with the Processor SDK and TI’s embedded processor solutions.

To simplify the end user experience, Processor SDK Linux AM64x installer provides everything needed as discussed below to create the embedded system from “scratch” :

  • Platform/board-support software and configuration files for Linux

  • U-Boot and Kernel sources and configuration files

  • An ARM cross-compiling toolchain as well as other host binaries and components

  • A Yocto/OE compliant filesystem and sources for example applications

  • A variety of scripts and Makefiles to automate certain tasks

  • Other components needed to build an embedded system that don’t fit neatly into one of the above buckets

  • Reference Examples, benchmarks

This release supports SR2.0 High Security - Field Securable (HS-FS) devices. For migration guide and other info, refer GP to HS-FS Migration Guide

2.1.2. Licensing

Please refer to the software manifests, which outlines the licensing status for all packages included in this release. The manifest can be found on the SDK download page or in the installed directory as indicated below.

2.1.3. Release 11.01.05.03

Released on July 2025

2.1.3.1. What’s new

Processor SDK Linux AM64X Release has following new features:

  • Second 2025 LTS Reference Release Including RT combined branch model - Kernel: PRU HW UART - Important Bug Fixes on top of Processor SDK 11.00.09.04 Release - Review Issue Tracker Section for the new fixes.

  • This release adds support for PRP Offload to the ICSSG prueth-driver. This allows to offload PRP functionality to the ICSSG hardware, which helps in reducing load on the A53 cores.
