Salam, 

I have downloaded application note from uCOS-II.com 

h**p://www.ucos-ii.com/downloads/appnotes/AN-1229.zip 

This file describe how interface between µC/OS-II & IAR 

I did all the instructions in this file. 
The project gives No errors or warnings but the Timer0 int is not 
working at all. 

The timer0 int is used to execute this function

void  Tmr_TickISR_Handler (void) 
{ 
    T0IR        = 0xFF;                 /* Clear timer #0 
interrupt                                    */ 
    OSTimeTick();                       /* If the interrupt is from 
the tick source, call OSTimeTick() */ 
    VICVectAddr = 0; 
}

As you seen OSTimeTick is updated with a rate say 100 times per 
second 

When Timer0 is not working , uCOS-II will stuck in the IDLE task and 
Scheduler will not work  

I don't know why Timer0 is not working. 

I have uploaded my project to [Files] section /uCOS-II/MICRIUM.rar 

I use 

IAR 4.30A KickStart 
Olimex LPC2129 board 
uCOS-II 2.76 


Thanks
