SysLink Release Notes

December 2011

This SysLink Release is targeted to SYS/BIOS 6-based platforms.

Introduction, Documentation, What's New, Upgrade Info, Compatibility Information, Device Support, Validation Info, Known Issues, Examples, Version Information, Technical Support.


SysLink is runtime software that simplifies the development of embedded applications in which either General-Purpose microprocessors (GPP) or DSPs communicate with each other. The SysLink product provides software connectivity between multiple processors. Each processor may run either an HLOS (e.g. Linux) or an RTOS (e.g. SYS/BIOS). In addition, a processor may also be designated as the master for another slave processor, and may be responsible for controlling the slave processor's execution (including boot-loading the slave).

The SysLink product provides the following services to frameworks and applications:

SYS/BIOS operating system is expected to be running on the slaves with all of these platforms.


The following documentation is available:

In addition, users are encouraged to monitor (and contribute to!) the TI Embedded Processors Wiki.

Release notes from previous releases are also available in the relnotes_archive directory.

What's New

Version Information

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. syslink_2_00_05_85.

Subsequent releases of patch upgrades will be identified by the patch number, ex. SysLink 2.00.01.XX with directory syslink_2_00_01_XX. Typically, these patches only include critical bug fixes.
