Introduction

SYS/BIOS 6.31.00.18 is an GA release of SYS/BIOS 6.31.00.

SYS/ BIOS is a real-time operating system that provides pre-emptive deterministic multithreading. The SYS/BIOS 6.x releases introduce a completely new SYS/BIOS kernel and toolset. The SYS/BIOS 6.x releases include numerous major enhancements, including completely new kernel APIs. They also include compatibility layers and tooling to facilitate easy porting of applications developed on DSP/BIOS 5.x releases.

A number of tools and libraries that were provided as an integrated part of DSP/BIOS 5.x releases must now be downloaded separately to obtain a functional solution. It is essential for even experienced DSP/BIOS users to refer to the Getting Started Guide and to the Upgrading and Compatibility Information section for further details.

Please read the Getting Started Guide for help installing and setting up your environment to use SYS/BIOS 6.31.00.18.

SDOCM00074509    BIOS 6: M3 Exception report mistakenly shows copy-to stack buffer address rather than thread's stack base.
SDOCM00074413    c28/Hwi_getHandle() API does not exist

SDOCM00073562    ti/sysbios/family/arm/Settings.xs: 'Ducati' is in 'ti.catalog.arm.nda' not 'ti.catalog.arm'

Benchmarks

    For a full description of Benchmarks please see the appendices in the SYS/BIOS 6 User's Guide. back to top

Versioning

All releases have 4 digits (M.mm.pp.bb). This includes GA and pre-releases (engineering, alpha/EA, beta, etc.). Pre-releases are denoted with a suffix (e.g. 6.30.00.00-eng or 6.30.00.10-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 (e.g. bios_6_30_00_00).

Subsequent releases of patch upgrades will be identified by the patch number, ex. SYS/BIOS 6.30.01.15 with directory bios_6_30_01_15. 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.
