The bundled evaluation version of IAR PowerPac supports three tasks for the RTOS and one open file in the file system.

Operating system

IAR PowerPac

CMX-RTX

CMX-Tiny+

uC/OS-II

RTXC Quadros

Unicoi Fusion

OSEK (ORTI)

OSE Epsilon

Micrium µC/OS-II

Micro Digital SMX RTOS

Each RTOS plugin installs a number of new windows in C-SPY, most importantly the task or thread list windows where task-specific breakpoints can be specified and task-specific steps executed. Different inspector windows display the contents of the internal data structures of the RTOS such as timers, queues, semaphores, resources and mailboxes.
