Upgrade and Compatibility Information

SYS/BIOS 6.70, 6.55, 6.53, 6.52, 6.51, 6.50, 6.46 and 6.45

Source compatible. All APIs are supported but all source files must be recompiled due to some structure/field changes in .h files.

SYS/BIOS 6.52, 6.51, 6.50, 6.46 and 6.45

POSIX support in SYS/BIOS has been changed which requires you make some modification. There are two areas affected by this change:

The kernel configuration script
The compiler include path

POSIX package name has changed, and the one configuration parameter name has been modified. The semantics remain the same.

Old Values

Package Name: ti.sysbios.posix
Config Param: Settings.supportsMutexPriority

New Values

Package Name: ti.posix.tirtos
Config Param: Settings.enableMutexPriority

These changes must be made in your kernel configuration script. The following is a typical setting using the old values:

var Settings = xdc.useModule(‘ti.sysbios.posix.Settings’);
Settings.supportsMutexPriority = true;

You will need to change these statements as follows:

var Settings = xdc.useModule(‘ti.posix.tirtos.Settings’);
Settings.enableMutexPriority = true;

When compiling, you will need to modify your include path to the new location of the POSIX header files. The include path now depends on the toolchain being used.

Old Value

/packages/ti/sysbios/posix

New Values

TI Compiler: /packages/ti/posix/ccs
GNU Compiler: /packages/ti/posix/gcc
IAR Compiler: /packages/ti/posix/iar

Some TI-supplied sample code was incorrectly including the posix headers with “#include <ti/posix/pthread.h>” instead of adding -I/pacakges/ti/sysbios/posix to the command line and using the correct “#include ”. Existing code that has includes of the form “#include <ti/sysbios/posix/pthread.h” will have to be updated to use the correct “#include ” along with updating your include path as stated above.

Benchmarks

Timing and Size Benchmarks

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.
