There are two options for running FreeRTOS on ARM Cortex-M7 microcontrollers.
|
||||
The best option depends on the revision of the ARM Cortex-M7 core in use. The
|
||||
revision is specified by an 'r' number, and a 'p' number, so will look something
|
||||
like 'r0p1'. Check the documentation for the microcontroller in use to find the
|
||||
revision of the Cortex-M7 core used in that microcontroller. If in doubt, use
|
||||
the FreeRTOS port provided specifically for r0p1 revisions, as that can be used
|
||||
with all core revisions.
|
||||
|
||||
The first option is to use the ARM Cortex-M4F port, and the second option is to
|
||||
use the Cortex-M7 r0p1 port - the latter containing a minor errata workaround.
|
||||
|
||||
If the revision of the ARM Cortex-M7 core is not r0p1 then either option can be
|
||||
used, but it is recommended to use the FreeRTOS ARM Cortex-M4F port located in
|
||||
the /FreeRTOS/Source/portable/GCC/ARM_CM4F directory.
|
||||
|
||||
If the revision of the ARM Cortex-M7 core is r0p1 then use the FreeRTOS ARM
|
||||
Cortex-M7 r0p1 port located in the /FreeRTOS/Source/portable/GCC/ARM_CM7/r0p1
|
||||
directory.

/*
|
||||
* A sample implementation of pvPortMalloc() that allows the heap to be defined
|
||||
* across multiple non-contigous blocks and combines (coalescences) adjacent
|
||||
* memory blocks as they are freed.
|
||||
*
|
||||
* See heap_1.c, heap_2.c, heap_3.c and heap_4.c for alternative
|
||||
* implementations, and the memory management pages of http://www.FreeRTOS.org
|
||||
* for more information.
|
||||
*
|
||||
* Usage notes:
|
||||
*
|
||||
* vPortDefineHeapRegions() ***must*** be called before pvPortMalloc().
|
||||
* pvPortMalloc() will be called if any task objects (tasks, queues, event
|
||||
* groups, etc.) are created, therefore vPortDefineHeapRegions() ***must*** be
|
||||
* called before any other objects are defined.
|
||||
*
|
||||
* vPortDefineHeapRegions() takes a single parameter. The parameter is an array
|
||||
* of HeapRegion_t structures. HeapRegion_t is defined in portable.h as
|
||||
*
|
||||
* typedef struct HeapRegion
|
||||
* {
|
||||
* uint8_t *pucStartAddress; << Start address of a block of memory that will be part of the heap.
|
||||
* size_t xSizeInBytes; << Size of the block of memory.
|
||||
* } HeapRegion_t;
|
||||
*
|
||||
* The array is terminated using a NULL zero sized region definition, and the
|
||||
* memory regions defined in the array ***must*** appear in address order from
|
||||
* low address to high address. So the following is a valid example of how
|
||||
* to use the function.
|
||||
*
|
||||
* HeapRegion_t xHeapRegions[] =
|
||||
* {
|
||||
* { ( uint8_t * ) 0x80000000UL, 0x10000 }, << Defines a block of 0x10000 bytes starting at address 0x80000000
|
||||
* { ( uint8_t * ) 0x90000000UL, 0xa0000 }, << Defines a block of 0xa0000 bytes starting at address of 0x90000000
|
||||
* { NULL, 0 } << Terminates the array.
|
||||
* };
|
||||
*
|
||||
* vPortDefineHeapRegions( xHeapRegions ); << Pass the array into vPortDefineHeapRegions().
|
