+ Change how queues are allocated and deleted so only one pvPortMalloc() or vPortFree() is required in place of the previous 2. + Where the TCB is allocated in relation to the stack is now dependent on the stack growth direction. The stack will not grow into the TCB. + Introduce the configAPPLICATION_ALLOCATED_HEAP constant to allow the application to provide the array used by heap_4.c as its heap. This allows the application writer to use qualifiers on the array to, for example, force the memory into faster RAM. Demo application: + Add demo for SAMA5D4 using IAR.
Each real time kernel port consists of three files that contain the core kernel components and are common to every port, and one or more files that are specific to a particular microcontroller and/or compiler. + The FreeRTOS/Source/Portable/MemMang directory contains the three sample memory allocators as described on the http://www.FreeRTOS.org WEB site. + The other directories each contain files specific to a particular microcontroller or compiler. For example, if you are interested in the GCC port for the ATMega323 microcontroller then the port specific files are contained in FreeRTOS/Source/Portable/GCC/ATMega323 directory. If this is the only port you are interested in then all the other directories can be ignored.
