DSP/BIOS Patch Release Notes

This release note is divided into the following sections:

Introduction, Documentation, What's New, Upgrading And Compatibility Information, Host Support, Dependencies, Device Support, Validation Information, Known Issues, Benchmarks, Versioning, Technical Support And Product Updates,


DSP/BIOS is a patch release based on DSP/BIOS 5.41.  This release includes separate installers for CCSv3 and CCSv4.  The target content (libraries and .h files) are identical in both installations.  The main difference is that different tools are provided in each release as necessary to work with CCSv3 or CCSv4.  It is ok to install both CCS versions on the same computer but they must not be installed under same root directory.

The main changes in this release are bug fixes (listed below).

Upgrading And Compatibility Information

DSP/BIOS is binary compatible with DSP/BIOS 5.33 (and all the way back to DSP/BIOS 5.21). Users do not need to recompile your source files or libraries when updating to BIOS 5.41. However users *must* rebuild their configuration since the generated linker .cmd file (<prog>cfg.cmd) is different.

Solaris host is no longer supported in this release. Customer-critical bug fixes to earlier releases will be available to Solaris users if required.

DSP/BIOS 5.41 does not support TMS320C54xx devices. Users of such devices should continue use DSP/BIOS 5.31.xx earlier releases. For customer-critical 54xx-related issues, TI will continue to provide fixes to earlier versions when needed.

Compatibility Key Definitions

Compatibility keys are intentionally independent of Marketing product numbers and are intended to:

  1. Enable tooling to identify incompatibilities between components, and
  2. Convey a level of compatibility between different releases to set end user expectations.

Compatibility keys are composed of 3 comma-delimited numbers - M,S,R - where:

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. or

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. bios_5_41_00_17.

Subsequent releases of patch upgrades will be identified by the patch number, ex. BIOS with directory bios_5_41_01_18. 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.
