TI-RTOS 1.21.00.09 Release Notes

This release note is divided into the following sections:

Introduction, Documentation, Products Included, What's New, Upgrade & Compatibility Information, Host Support, Dependencies, Device Support, Validation Info, Known Issues, Examples, Version Information, Technical Support.

Introduction

This is an General Availability release of TI-RTOS . This version of TI-RTOS requires CCS 5.5.

MSP430 support in this release is at a "beta" level. All of the other components in this release of TI-RTOS are at a GA level.

The TI-RTOS delivers components that enable engineers to develop applications on Texas Instruments micro-controller devices. The product is comprised of multiple software components and examples of how to use these components together.

The TI-RTOS gives developers a one-stop RTOS solution for developing applications for TI embedded microcontrollers. It provides an OS kernel, communications support, drivers, and more. It is tightly integrated with TIs Code Composer Studio development environment. In addition, examples are provided to demonstrate the use of each functional area and each supported device and as a starting point for your own projects.

Documentation

The following documentation is available:

Release notes from previous releases are also available in the release notes archive directory.

Products Included

The following is a list of all the products bundled into the TI-RTOS installation. Note these products only support ARM and C2xxx devices (this was done to reduce installer and installation size).
* XDCtools is installed at the same level at TI-RTOS. If the xdctools_3_25_04_88 version is already present at that location, that version is used.
** refer to <TIRTOS_Install_dir>\products\*Ware>\TI-RTOS.README for more details

Upgrade and Compatibility Information

When migrating an application that uses TI-RTOS 1.20.00.28 to TI-RTOS 1.21.00.09, the following steps must be taken:
    1. Libraries: The StellarisWare libraries (e.g. "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/TivaWare_C_Series-2.0b/driverlib/ccs-cm4f/Debug/driverlib-cm4f.lib") must be changed to point to the TivaWare libraries (e.g. "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/TivaWare_C_Series-2.0.1.11577a/driverlib/ccs/Debug/driverlib.lib")
    2. Include Paths: The StellarisWare include paths (e.g. "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/TivaWare_C_Series-2.0b") must be changed to point to the TivaWare path (e.g. "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/TivaWare_C_Series-2.0.1.11577a").

Version Information

All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, EA, beta, etc.). Pre-releases are denoted with a suffix (e.g. 1.01.00.15_eng or 1.01.00.21-beta).

This product's version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and b is an unrestricted set of digits used as an incrementing build counter.

To support multiple side-by-side installations of the product, the product version is encoded in the top level directory, ex. tirtos_1_00_01_11.

Subsequent releases of patch upgrades will be identified by the patch number, ex. TI-RTOS 1.00.00.68 with directory tirtos_1_00_01_70. Typically, these patches only include critical bug fixes.

Please note that version numbers and compatibility keys are NOT the same. For an explanation of compatibility keys, please refer to the 'Upgrade and Compatibility Information' section.

Technical Support

For technical support, please refer to the Texas Instruments E2E BIOS Support Forum http://e2e.ti.com/support/embedded/bios/default.aspx or other forums in http://e2e.ti.com/ as needed.
