    Hi,

    Its better to check with the RTOS folks based on what RTOS you are porting on to TMS570.

    But in general for what you have described above, semaphore should do the job.

    Semaphores are used to deal with the conflicts that might arise when a resource is shared. In the meanwhile Message queues are used mainly to post more than one message to a task which can read on the message queue when it finds time to consume and process. Hope this helps, but pls check with the respective RTOS folks to get more details.
