Upgrade and Compatibility Information
SYS/BIOS 6.75
- Binary compatible. Libaries built against SYS/BIOS 6.75.0x .h files can be used with 6.76.0x.
SYS/BIOS 6.73, 6.70, 6.55, 6.53, 6.52, 6.51, 6.50, 6.46 and 6.45
- Source compatible with one exception (Task_setPri()). All APIs are supported but all source files must be recompiled due to some structure/field changes in .h files.
- Task_setPri() return value changed from UInt to Int. The return value was inconsistent with the priority parameter to the function call itself.
- Removed support for the following devices/targets
- MSP430
- C64x+
- C66x big endian (C66x little endian is still supported)
- Cortex-R4 32-bit mode (Cortex-R4 thumb2 mode is still supported)
Migrating GCC Projects Built with SYS/BIOS v6.50 or older to SYS/BIOS v6.52

Validation Information

Known Issues
- This release was not tested for the DM814X devices. There were no changes that should impact DM814X, but the regression tests were not run on this device. We therefore recommend using SYS/BIOS 6.75.0x (or earlier) for DM814X.
- CCDSK-3465 – CCS v9.0 does not include the “Resource Explorer (Classic)” tooling that is used to navigate and find SYS/BIOS examples. CCSv8.3.0 is recommended until this issue is resolved in CCSv9.1 or later.
Benchmarks
For a full description of Benchmarks please see the appendices in the SYS/BIOS 6 User’s Guide.
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 bb 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.
