Tool chain used for build

The following tools have been used:

Compiler:  IAR ICCARM   V5.11.0.50622
Assembler: IAR IASMARM  V5.11.0.50622
Librarian: IAR AR       
Workbench: IAR IARIDEPM 5.1.0.417

New features

Version 3.60a1

1. MMU and cache handling functions added
   embOS for ARM now comes with functions to initialize the MMU and cache of ARM9 and ARM720 CPUs.
   Functions to invalidate and clean the cache are provided also.

Version 3.60a

1. New embOS sources V3.60a used
   The new of embOS version 3.60a are described in the embOS generic manual and release notes.

Version 3.52a

1. IAR compiler V5.10 supported
   embOS version 3.52a for ARM can be used with IAR compiler version V5.10 and the new IAR embedded Workbench V5.0.
   A version for the older IAR workbench V4 and compiler version 4.41A/4.42A is shipped together with the new version of embOS for ARM and IAR compiler.

Improvements

Version 3.52e

1. BSP for ATMEL AT91SAM9260 optimized
   The sample start project for AT91SAM9260 now initializes the MMU and caches to speed up the CPU.

Version 3.52a

1. NONE
   Initial version for IAR compiler V5.1x

Program corrections

Version 3.60a

1. MMU initialization for ARM 926 corrected.
   The MMU enable function called from __low_level_init() performed a cache flush which might have caused writing invalid data onto the stack which then caused a system crash.
   The problem existed in all previous versions of embOS for ARM and is fixed with version 3.60a.

Version 3.52d

1. Task switch corrected in ARM core 5 libraries
   The task switch for ARM mode libraries and core type 5 did not work, the system crashed.
   All libraries named os5tpa* were affected.
   The libraries for thumb mode and all core type 4 worked as expected.
   The problem existed in version 3.52a of embOS for ARM and IAR only and is fixed with version 3.52d.

Version 3.52a

1. NONE
   Initial version for IAR compiler V5.1x

Known problems/limitations

Version 3.52a

1. NONE
   Initial version for IAR compiler V5.1x
