Hello Nicolas,
The sysPhysMemDesc[] array is a data structure usually defined in the
BSP's sysLib.c file that describes the various memory areas available
on the board. One and only one of the entries corresponds to the
physical memory used by VxWorks for its text, data, heap, etc.
Additional entries describing physical memory banks can appear in the
sysPhysMemDesc[] array and are therefore known to the OS but they are
not, by default, used by VxWorks for its heap.
Once such physical memory is described via an entry in the
sysPhysMemDesc[] array it is possible to use API such memPartCreate()
and memPartAddToPool() to make use of it.
I recommend that you read the VxWorks BSP Developer's Guide where the
array is described, and also the VxWorks Architecture Supplement where
specific usage scenarios of this arrays are discussed.
Hope this helps,
