CrossStudio: C++ interrupt service

2005-02-07 by fl429

Hi, folks,

I am trying out a few things on a IAR Kickstart board, with 
CrossStudio 1.3. 

I'd like to write code in C++ instead of C. My test C++ code ran ok 
until I added an interrupt service routine, for Timer0 as my test 
example.

I have a ISR like this: (in a .cpp file)

static void timer0ISR(void) __attribute__ ((interrupt ("IRQ")));

static void timer0ISR()
{
    // doing something here


}

void SetupTimer0()
{
    //
    // Init VIC here, not shown
    //
    VICVectAddr0 = (unsigned int)timer0ISR;
    //
    // etc
	
}

The problem is the result code always calls the default DO-Nothing 
handler in the "Philips_210x_startup.s" and stalls there.

The same piece of code in C seems ok.

Any ideas ?

Thanks,

Lei
