RTOS CCS Error... help

[TirthankarMukherjee]

Code:

#include "G:\program PIC\16f877A\real_rtos1.h"

#use rtos(timer=0,minor_cycle=500ms)

#task(rate=500ms,max=100ms)

#task(rate=1000ms,max=100ms)

{
  int i;
  printf("hello USA !");
 // delay_ms(50);
  for(i=0;i<50;i++)
  {
  printf("CCS Rocks !!");
  }

Error

Code:

USE parameter value is out of range :: Minor cycle too short for this timer 

Cant compile my first RTOS in CCS 4.058.. [lease help me to detect the problem.... Basically I want to do object detection with IR and run my stepper motor... so want to implement RTOS functions... but I got stuck while compiling....

A newbie is waiting for answers....

Thanks in Advance...

where are your processor definitions?
the rtos uses the clock speed to make some decisions.
