This change allows the implementation of a priority ceiling protocol into
message servers threads. Threads serving messages by priority and threads
serving messages in FIFO orded can exist at the same time in the system.
This feature can be enabled or disabled by removing the option
CH_USE_MESSAGES_PRIORITY into the chconf.h file.
This feature can be enabled or disabled by toggling the option
CH_USE_MESSAGES_PRIORITY into the chconf.h file (disabled by default, old
behavior).
Note: This option brings a small overhead when sending a message regardless
if in FIFO or priority order, if you dont need priority ordering for your
messages it is better disable the feature in chconf.h. It also saves some
space.
messages it is better to keep disabled the feature in chconf.h.
- Added to the ARM demos load scripts the capability to load code in RAM
instead flash, the function must be marked as:
