Getting started with RTOS

[geot]

Hello forum,
I've worked for almost 3 years with Atmel's AVR, Cortex-M3, Cortex-M4 microcontrollers. I never tried to do something with RTOS, though.
I decided to expand this field and I'm looking for a book or books or some entry point regarding RTOS to learn few things about it.

Thanks in advance!

Thanks! I forgot to mention that I'd like something more basic for start, something more generic, not a theory-documentation of a particular distribution.
In the meantime I will take a look into freeRTOS.

Thanks again.

Maybe you can start looking at this https://www.freertos.org/, there is a tutorial on that site. I work on FPGA designs, but in places I've worked they've used either freeRTOS, VxWorks, or MicroC/OS-?.

Then look at the wiki page on RTOS https://en.wikipedia.org/wiki/Real-time_operating_system.

Primarily the RTOS has to do three things: Scheduling, thread switching, and interrupt handling. How it's done/used with your code immediately becomes non-generic as it is implementation specific.
