Дока качественная. В частности, подробно расписана архитектура ОСи и ее имплементация, разжеваны примеры и пр.

Motorola/Freescale ColdFire RTOS port - очень интересно в свете моих последних изысканий
http://www.freertos.org/portcoldfire.html

Наиболее интересные фичи
* both preemptive and cooperative options.
* supports both tasks and co-routines.

Вопросы:

1. Интересно, в чем она проигрывает uCOS?
2. Супергибкость ОСи - это хорошо (от PIC до ColdFire и x86). Но не накладывает ли это какие-нибудь ограничения на структуру ОСи?
3. Интересно мнение о FreeRTOS от юзавших ее в реальных проектах.

V5.0.2
+ Updated the PIC32 port to allow queue API calls to be used from
interrupts above the kernel interrupt priority, and to allow full
interrupt nesting. Task stack usages has also been reduced.
+ Added a new PowerPC port that demonstrates how the trace macros can be
used to allow the use of a floating point co-processor. The
traceTASK_SWITCHED_OUT() and traceTASK_SWITCHED_INT() macros are used to
save and restore the floating point context respectively for those tasks
that actually use floating point operations.
+ BUG FIX: The first PPC405 port contained a bug in that it did not leave
adequate space above the stack for the backchain to be saved when a task
started to execute for the first time.
+ Updated queue.c to add in the means to allow interrupt nesting and for
queue API functions to be called from interrupts that have a priority
above the kernel priority. This is only supported on PIC32 ports thus
far.
+ Fixed the compiler warnings that were generated when the latest version
of WinAVR was used.
+ Remove all inline usage of 'inline' from the core kernel code.
+ Added the queue registry feature. The queue registry is provided as a
means for kernel aware debuggers to locate queue definitions. It has no
purpose unless you are using a kernel aware debugger. The queue registry
will only be used when configQUEUE_REGISTRY_SIZE is greater than zero.
+ Added the ST Cortex-M3 drivers into the Demo/Common/Drivers directory to
prevent them from having to be included in multiple demos.
+ Added a Keil STM32 demo application.
+ Changed the blocktim.c test files as it is no longer legitimate for all
ports to call queue API functions from within a critical section.
+ Added the IntQueue.c test file to test the calling of queue API functions
from different interrupt priority levels, and test interrupt nesting.
