SDOCM00114097    A8 TimestampProvider 64 bit timestamps jump backwards sometimes
SDOCM00114095    Hwi_initStack() routine may generate code that corrupts the stack during boot time (gcc v4.8 Arm issue)
SDOCM00113959    ti/sysbios/smp/LoggerBuf Timestamp proxy is set to early resulting in TimestampNull (no timestamps in the logs)
SDOCM00113940    F2837x initFlash() code incorrectly programs the flash wait states
SDOCM00113935    ARP32/EVE Hwi_interruptClear() should not clear the IFR register (problem in Timer/IPC intitialization)
SDOCM00113858    Need 2 new Cache APIs for global L1D operations on c64+/c66
SDOCM00113850    Add ASID tagging support for Cortex-A8 and new API to invalidate TLB
SDOCM00113847    BIOS needs to support creating a secure context
SDOCM00113830    C28x Hwi_switchAndRun() internal assembly function should use XAR5 instead of XAR3 to follow compiler conventions
SDOCM00113826    GateMutexPri_enter() is not thread safe, allowing mutliple threads to enter the gate simultaneously.
SDOCM00113823    Tasks failing to acquire a GateMutexPri gate are not queued in task priority order.
SDOCM00113329    SMP version of Task_yield() and Task_setAffinity() has a bug

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.
