Look at attached file. It is simple program example from CodeWarrior 10.5.1 wizard.

This example uses syscall. Compare your project and this program example.

Have a great day,

Thanks, Pasha)
I have a problem with syscall. I'm trying to code a simple task sched without OS... it's like a DCB (deffered callback) manager. When my task is set to task queue, manager calls a system_call() and IRQ_SYSCALL handler works with queue (execute tasks). But i can't see other async interrupts, its not execute(( It seems like current task is executed with highest priority, may be system_call has a highest priority.... Please, help me!!!!!!!!!!!
