Introduction

This is an General Availability release of TI-RTOS (previously called MCU SDK).

The TI-RTOS delivers components that enable engineers to develop applications on Texas Instruments micro-controller devices. The product is compromised 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 TI’s 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:

Upgrade and Compatibility Information

When migrating an application that uses MCUSDK 1.00.xx to TI-RTOS 1.01.00.25, the following steps must be taken

1. The following options must be changed in the project’s properties (if present)
        i. Move to the new version in General->RTSC->Products and Repositories
        Deselect the "MCU SDK" version that you are currently using.
        Select the TI-RTOS 1.01.00.25 version.

        ii. Point to the new MWare include path in Build->ARM Compiler->Include Options*
"${COM_TI_RTSC_MCUSDK_INSTALL_DIR}/products/MWare_vXXX/MWare"
    becomes
   "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/MWare_v110a/MWare"

        iii. Point to the new MWare libraries in Build->ARM Linker->File Search Path*
"${COM_TI_RTSC_MCUSDK_INSTALL_DIR}/products/MWare_vXXX/MWare/driverlib/ccs/Debug/driverlib.lib"
    becomes
  "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/MWare_v110a/MWare/driverlib/ccs/Debug/driverlib.lib"

  "${COM_TI_RTSC_MCUSDK_INSTALL_DIR}/products/MWare_vXXX/MWare/usblib/ccs/Debug/usblib.lib"
    becomes
   "${COM_TI_RTSC_TIRTOS_INSTALL_DIR}/products/MWare_v110a/MWare/usblib/ccs/Debug/usblib.lib"

    *For Stellaris boards, StellarisWare_YYYY becomes StellarisWare_9453e.

2. In the configuration file (i.e. .cfg file), the two lines must be changed (if present)

    var McuSdk = xdc.useModule('ti.mcusdk.McuSdk');
    var SysFlex = xdc.useModule('ti.mcusdk.utils.SysFlex');
    becomes
    var TIRTOS = xdc.useModule('ti.tirtos.TIRTOS');
    var SysFlex = xdc.useModule('ti.tirtos.utils.SysFlex');

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 Instrument’s E2E BIOS Support Forum http://e2e.ti.com/support/embedded/bios/default.aspx or other forums in http://e2e.ti.com/ as needed.
