Real Time Application Design Using FreeRTOS in small embedded systems

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.

*** VERY IMPORTANT INFORMATION ON UPGRADING TO FREERTOS.ORG V5.0.0 ***

The parameters to the functions xQueueSendFromISR(), xQueueSendToFrontFromISR(), xQueueSendToBackFromISR() and xSemaphoreGiveFromISR() have changed. You must update all calls to these functions to use the new calling convention! Your compiler might not issue any type mismatch warnings!

See http://www.FreeRTOS.org/upgrading.html for full information.

It is understood that this change may cause some minor inconvenience. The change has been made in response to numerous change requests, and makes this family of API functions consistent with the calling convention used by xQueueReceiveFromISR(). I hope you agree that the benefits outweigh the inconvenience.

***Remember*** - all calls to xQueueSendFromISR(), xQueueSendToFrontFromISR(), xQueueSendToBackFromISR() and xSemaphoreGiveFromISR() MUST be updated to use the new calling convention.
