* Add XMOS XCore ports Some minor modifications are also made to the kernel to support the XCore compiler's automatic stack size calculation. * Update kernel to support SMP The XMOS XCore ports are also updated to support SMP. * Fix compiler warnings in xcore ports The port set and clear interrupt mask from ISR macros were removed from the ports so that the default macros found in FreeRTOS.h are used instead. The default macros do not result in warnings when they are used. * Remove inline function from timers.h Inline function converted to macro. This should now build when optimizations are off and inlining is disabled. * Fix compiler warnings in xcore ports and tasks.c * fixed documentation for ulTaskNotifyTake() and ulTaskNotifyTakeIndexed() * spelling fixes for tasks.c Co-authored-by: Michael Bruno <mikeb@xmos.com>

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/RVDS/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/RVDS/ARM_CM7/r0p1
|
|
directory. |
