IAR PowerPac RTOS编译连接出错
Error: Segment INTVEC (size: 0x410 align: 0x2) is too long for segment definition. Atleast 0x3d0 more bytes needed. The problem occurred while processing the segment
placement command "-Z(CODE)INTVEC=00-3F", where at the moment of placement the
available memory ranges were "CODE:0-3f"
Reserved ranges relevant to this placement:
0-3f INTVEC

IAR PowerPac RTOS is a priority controlled real-time operating system, designed to be used as the foundation for development of embedded real-time applications. It is optimized for minimum memory consumption in both RAM and ROM, as well as high speed and versatility.
The kernel of IAR PowerPac RTOS is fully interruptible and can be used in time critical situations. Despite its size and efficiency, IAR PowerPac RTOS features the entire range of communication mechanisms such as mailboxes, events and different kinds of semaphores. All tasks and communication instances can be dynamically created, deleted and configured, and the priorities can be fully controlled.
Key features
？ Preemptive scheduling
？ Round-robin scheduling for tasks with identical priorities
？ Preemptions can be disabled for entire tasks or for sections of a program
？ No configuration needed
？ Up to 255 priorities
？ Unlimited number of tasks, semaphores, mailboxes and software timers (limited by available memory only)
？ Unlimited number of software timers with freely selected time resolution
？ Full interrupt support; most API functions can be used from within the Interrupt Service Routines (ISRs)
？ Zero interrupt latency time
？ Nested interrupts permitted
？ Task switches even in interrupt handlers
？ Very fast context switch times
？ Easy-to-start applications and projects
？ Small memory footprint
？ Core written in assembly language
？ All API functions callable from C, C++ and assembly language
