Introduction

This is a GA release of TI-RTOS. 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. 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 the 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. This release notes covers all of the TI-RTOS products being released (i.e., for TivaC and SimpleLink).

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 inEK-TM4C1294XL 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.
