Introduction

SYS/BIOS 6.30.03.46 is a Patch release of SYS/BIOS 6.30.

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 6.30.03.46.

What's New

SYS/BIOS 6.30.03.46 Patch Release (this release).

This release is based on DSP/BIOS 6.30.02. 

Notes on this release:

Defects Fixed:
    ID                               Headline
    SDOCM00074415    c28/Hwi_getHandle() API does not exist
    SDOCM00074353    if the idle task is disabled, BIOS can spin in infinite loop with interrupts disabled (C6x/whole_program issue)
    SDOCM00074269    example .cfg files need to use 'var' for all static create instances (so objects can be seen in xgconf!)
    SDOCM00074263    (OMAP4/Power) Restore of NVIC state should be moved to after all other context has been restored (Ducati)
    SDOCM00073999    (OMAP4/Power) Remove Hwi_disable/Hwi_restore from the Ducati Power_suspend API
    SDOCM00073718    ti/sysbios/family/arm/Settings.xs: 'Ducati' is in 'ti.catalog.arm.nda' not 'ti.catalog.arm'
    SDOCM00073701    unicache APIs should use line-mode functions for smaller buffer sizes
    SDOCM00073699    GateDualCore_sync() API stalls sometimes

Upgrading and Compatibility Information

SYS/BIOS 6.x releases have many significant changes from DSP/BIOS 5.x.  It is important to understand the information below in order to successfully use SYS/BIOS 6.x and to migrate applications from DSP/BIOS 5.x.

DA830 ROM

BIOS 6.30 cannot be used with the DA830 ROM.  BIOS 6.21 is the preferred version for DA830 ROM.

The 'ti.sdo.io' and 'ti.sdo.utils' packages are no longer provided with SYS/BIOS

These packages are now provided in a separate "IPC" product.  Users of these packages simply need to add this other product directory to their package path (XDCPATH) to build their applications.

The ti.sysbios.ipc package and its modules have been deprecated

The Semaphore, Event, and Mailbox modules were moved from the ti.sysbios.ipc package into the ti.sysbios.knl package. Please update your applications to use the ti.sysbios.knl package versions of the Semaphore, Event, and Mailbox modules. Using the ipc package versions of these modules will result in build warnings. In a subsequent release of BIOS, using any module within the ipc package will result in a build error.
   
The ti.sysbios.family.arm.m3.Exception module has been deprecated

The ti.sysbios.family.arm.m3.Exception module functionality has been enhanced and merged into the ti.sysbios.family.arm.m3.Hwi module. Please update your applications to use the ti.sysbios.family.arm.m3.Hwi module to configure exception handling. By default, exceptions will be reported to CIO with an Error message. Details of the exception can be seen using Hwi module's "Exception" ROV view. At the expense of additonal code size, some of this detailed information can ALSO be routed to the CIO console by setting the Hwi.enableException configuration flag to true.

Placing of sections using MEM configs is no longer supported (ie MEM.TEXTSEG is unsupported)

All of the legacy MEM memory segment placment functionality has been removed. Legacy BIOS users must use Program.sectMap to place memory sections.

The ti.sysbios.family.c64p.Cache.initSize configuration item is no longer supported

The ti.sysbios.family.c64p.Cache module no longer supports setting the Cache sizes. These settings are now managed within a platform and can be configured using the platform wizard.

SYS/BIOS no longer contains all the tools and objects you will need

The XDC tools now provide the SYS/BIOS configuration tools and Platform support. XDC also includes a minimal run-time environment that provides the LOG, System, Asserts, Error handling, Timestamp, and Memory Allocation APIs that will be used by SYS/BIOS applications.  Please refer to the Getting Started Guide on where to download the XDC tools and run-time.

Migrating DSP/BIOS 5.x applications to SYS/BIOS 6.x

SYS/BIOS 6.x has different APIs compared to those in DSP/BIOS 5.x. Configuration scripts are also incompatible between the two releases.  To provide easy migration of DSP/BIOS 5.x applications, an API compatibility layer is provided along with a conversion tool that converts configuration scripts to work with XDC and SYS/BIOS 6.x.  The API compatibility layer provides 100% C source code compatibility with the exception of a few APIs that are no longer supported.  For more complete details of migrating DSP/BIOS 5.x applications and configuration scripts, please refer to Migrating a DSP/BIOS 5 Application to SYS/BIOS 6.

As mentioned above, some APIs previously supported in DSP/BIOS 5.x releases will no longer be supported in this release or the compatibility layer.  Complete details are provided in the Migration document referenced above.

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.
