Akalon Embedded OS (RTOS) Files

Akalon Embedded RTOS
====================

Version	 : 2014-1013
Notes    : User Manual can be found under ./docs

Changes  : * The first ARM bsp, the SAM9-L9260 is now working with the 
             Command Line Interface (CLI). No more work will be done on this
             bsp since the chip on the ARM microprocessor on the SAM9-L9260 
             board is now obsolete. I will start porting Akalon to the 
             Raspberry Pi.
              
           * Got rid of the Kernel and Interrupt Tasks and replaced them with
             the Idle Task. Instead of 6 task switches for handling an 
             interrupt, Akalon now only requires 3 !!

Changes  : * Initial ARM Port (still a work in progress). Got task switching
             to work with interrupts on the Olimex SAM9-L9260 board. When the
             cli is working via the serial port, I will switch to the 
             Raspberry Pi platform.

           * Simplified the build. Now, to build, change to the bsp directory
             and type "make clean all". No more build scripts !!!

Version	 : 2013-0421
Notes    : User Manual can be found under ./docs

Changes  : * CLI can now show global variables. 

           * New Scheduler is complete. This would make it easier to port
             it into a multi-core system. 

           * Introduced task_sleep() and task_wake(). All drivers are now
             using task_wake(). This will eventually be the only OS call
             that can be made from in interrupt context.

           * Version numbers now have the format YYYY-MMDD

Version	 : V2012-09-23
Notes    : User Manual can be found under ./docs

Changes  : * Partial implementation of new scheduler. Got rid of the 
             Ready Queue. It now runs faster ! 

           * New Shell which will now be called the Command Line Interface.
             All non-static C functions are now automatically available from 
             the CLI. The old tables are gone !!!

Changes  : * Renamed NULL_PTR to NULL which is more standard.
           * Put in a speed check.
           
The next version will have a new scheduler to handle multiple cores since
this is the future.

Changes  : * Removed the help "strings" from the command menu. They are now
             under a help table in the bsp directory. 
           * Started on the ARM port. Had to put all on hold because I moved
             from the UK to Canada. A ? 
           * Got rid of multiple libraries. All code (except the BSP) is now
             in one library file ./lib/libakalon-<ARCH>-<CPU>.a
           * Cleaned up the Build files.
           * Interrupt Cleanups
