New features

Version 3.60d

Update to new embOS sources V3.60d
embOS for ARM and RVDS 3.0 was updated to the new embOS sources V3.60d.
All new features, improvements and modifications are described in the generic embOS release notes.

Version 3.32m

OS_TimerEx, Extended timer implemented
Extended timers are software timers which call a user defined callback function when the timer expires.
In comparison to normal embOS timers, a parameter is passed to the timer callback function.
The parameter value is initialized during timer creation.

Version 3.32k

NEC SoCLite+ series supported
embOS for ARM RVDS now comes with a start project for NEC SoCLitePlus startkit.
The project is prepared for debugging in Flash or SDRAM using JLink RDI.

Version 3.32j

STR71x series supported
embOS for ARM RVDS now comes with a start project for ST STR71x CPUs.
OS_CSemaRequest implemented
May be used to decrement a caounting semaphore, if a signal is available.
The function never blocks the calling task and delivers a result which indicates whether the semaphore was available.

Version 3.32f

OS_INIT_SYS_LOCKS() implemented
May be used to include initialization code for thread safe system libraries.
If defined, this new function is called from OS_InitKern().

Version 3.32d

OS_Q_GetPtrTimed() implemented
New queue retrieval function which waits for a message with specified timeout.

Version 3.32c

All features of generic 3.32c kernel supported.

Improvements

Version 3.32i

Task switch to OS_Idle() modified.
The call of OS_Idle() from OS_ChangeTask can be overwritten (inhibited) by defining the macro OS_IDLE() which is norammly defined as OS_Idle().
This allows task switching via an exception for specific CPU/compiler versions.

Version 3.32g

Pointer comparison improved for fixed size memory pools (OS_MEMF module).
Some compiler produced wrong pointer comparison code in far memory model.
For specific CPU/compiler versions, the new OS_POINTER_TO_VALUE() function was inroduced to deliver correct results in pointer comparison.

Version 3.32c

First version. None.

Program corrections

Version 3.32l

OS_EVENT_Delete() corrected
OS_EVENT_Delete() did not work correctly. OS_LeaveRegion() was called inside the function without calling OS_EnterRegion() bfore.
In debug builds of embOS, the error handler OS_Error() was called with error 151 (OS_ERR_LEAVEREGION_BEFORE_ENTERREGION).
In release builds the system was blocked because the underflow of region count inhibts all further task switches, or system crashes, because incrementing the region count the next time allows task switches instead of blocking them. The problem existed in all previous versions and is fixed with version 3.32l.
Round-robin task switching corrected.
Round robin task switching did not work correctly in previous version. A task which was blocked for some reason could be activated. The system crashed during task switch.
The problem existed since version 3.32j and is fixed with version 3.32l.

Version 3.32k

Handler function _OS_OnTx() for serial communication to embOSView corrected.
The transmission handler for communication with embOSView might have sent incorrect data to embOSView, because internal control state was updated after sending the data.
The problem occurred on a new embOS port for a specific CPU only and is fixed with version 3.32k.

Version 3.32h

OS_Error() was required in release build when resource semaphores were used.
When using release build libraries and resource semaphores, the embOS error handler OS_Error() was required and the file OS_Error.c had to be compiled and linked in a project.
The problem existed since version 3.28i of embOS and is fixed with version 3.32h.

Version 3.32e

OS_GetMessageCnt() corrected.
The type of the retun value of OS_GetMessageCnt() was an unsigned integer in release builds, but an integer in debubg builds.
This was corrected to return an unsigned integer in all builds.
The problem existed in all previous versions of embOS end is fixed with version 3.32e.

Version 3.32c

First version. None.

Known problems/limitations

Version 3.32c

First version. None.
