SW Interrupt on Iar (Vectors)

Hi all,

I'm implementing a software interrupt on STR71x.

I use Iar tools, and would like to know how to add the interrupt

in vector function.

An example of vector table could be nice !

Thanks,

Regards,

Thanks Zouh,

But i already found this post;

That's not dealing with Iar environment.

So, It differ . and it doesn't reply to my interrogation

around vector table and its configuratin for SWI

Rgds,

Oh ok that's what missed me. (to declare in the SWIt).

Thanks Zouh.

Dear Zouhair:

Could you explain more ?

I try C/C++ Guide P.19

#pragma swi_number=0x23

__swi __arm int swi_function(int a, int b);

and I declare

int swi_function(int a, int b)

{

return (a+b);

}

3rd step at P.20 of Guide

I add swi_handler.s79 to my project

At SWI_Handler routine, I add __iar_swi_handler()

But I find the assemble code is BL swi_function not asm 23

So never trigger SWI_Handler function.

What is wrong with me ?

Or I misunderstand the Guide.

Thank you.
