Release 04.00.00

Released June 2017

What's New

  • 2017 LTS Update
    • First release in 2017 LTS (Kernel: 4.9, U-boot: 2017.01, gcc: 6.2.1, Yocto 2.2 (morty))
  • New Platforms
    • OMAP-L138
  • New Features
    • HSR/PRP on AM572x with PRU offload. : Run NetJury tests using snmp-d with IEC-62439-3 MIB support
    • Jailhouse Virtualization: Run TI-RTOS application (ICSS-EMAC LLD) in inmate
    • Chromium Browser
    • Userspace access of ICSS on AM335x, AM437x, AM57x - enable protocols such as EtherCAT Master
    • Waylandsink to support i420 input on AM437x
    • BigData IPC example to serve as a template for customers to develop ARM<->DSP IPC based applications
    • AM57x: use VPE for chroma downsampling and scaling of USB camera output
    • Support USB webcam gadget mode
    • Enable CPU hotplug in RT Linux Kernel
    • Remove dependency on Code Composer Studio for AM57x Yocto builds, as M4 toolchain to build IPUMM firmware is now available publicly as a standalone download, outside of CCS
    • OpenCL: Added support for configuring the Multicore tools daemon using a JSON file (link)

Installation and Usage

The Software Developer's Guide provides instructions on how to setup up your Linux development environment, install the SDK and start your development.  It also includes User's Guides for various Example Applications and Code Composer Studio.

Host Support

The Processor SDK is developed, built and verified on Ubuntu 14.04 and 16.04.   Details on how to create a virtual machine to load Ubuntu 14.04 are described in this page.


Processor SDK Installer is 64-bit, and installs only on 64-bit host machine. Support for 32-bit host is dropped as Linaro toolchain is available only for 64-bit machines
