    Hi Bindu,

    Have you read the "SYS/BIOS User Guide" (included in the docs folder in sysbios package)?
    It shall answer all your questions.

    Hi,

    Yes, this guide. Although there is a newer revision (I personally have "M" not "J")...
    Chapter on "Threading Modules" will answer your questions about preemption an priorities. Basically it is all priority based but it also includes an example of how to implement time slicing.

    Chapter in the beginning "Creating SYS/BIOS projects" shows how to create the included example projects. If you look into them you'll find examples for message queue, semaphores and other facilities about which you asked.

    Hope that helps,
    Vasili
