Urgent IAR EWARM with uCOS-II :-( ?

Started by eng_amrahmed2011 March 14, 2006
Salam,

Urgent, I need help :-(
I can't get uCOS-II work with IAR (for ARM)

Can you please send any ready project that works with these boards 
(or any LPC2000)

MCB2100
MCB2130
Olimex LPC2129

I use IAR EWARM 4.31A

Project at
http://groups.yahoo.com/group/lpc2000/files/uCOS-II/

Or

Can you take look to my project and tell me what is the wrong ?

Note: I removed the uCOS-II source code from this project.

C:\MICRIUM\SOFTWARE\uCOS-II\Source (Put your uCOS-II here)

uCOS-II version should be 2.67 or up.

Thanks for any help

	You could start by providing some information on what your problem is. 
What 
is the symptom?  Is it a compilation issue?

My problem is not in the compilation.

I compile the project with No errors and No warnings.

My problem there is no multitasking.

Cause i think the timer0 interrupt is not working.

I set breakpoint at T0IR = 0xff;

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

But no thing happen and there are no response in the leds.

Maybe too obvious but sometimes the obvious can catch us out, have you:

+ Stepped through the timer setup code.
+ Made sure the correct header files are included (to get register addresses 
correct).
+ Checked that interrupts are (globally) enabled.

This same code was running on an Olimex LPC2129 board over a month ago, no
problem.

4.30A

The code you posted initially had a while(1) in your timer interrupt.

My suggestion is download Micrium application note again.
Do-not-change-anything in any of the files.  Extract the .rar I sent you,
and overwrite appropriate directories.  It will work by pressing debug if
you use J-Link.
