Don't use noreturn. It signals to the compiler that your function will
not return (i.e. do an infinite loop).
Ok, this is good to know.
Use the interrupt directive for interrupt handlers. That makes them
emit the iret instruction instead of ret t

One thing you need is the interrupt procedure directive:
procedure TIMER0_overflow; interrupt; public name 'TIMER0_COMPA_ISR';
Otherwise it'l

Ok I got it

What compiler
Not sure the timer initialization is right, but it looks ok.

What compiler commandline are you using?

Hi, I am experimenting with the avr embedded compiler from trunk and am
trying to set an interrupt. I am not sure how to do it. The interrupt I
want to change is TIMER0_COMPA_ISR.
I see in the startup code there is:
.weak TIMER0_COMPA_ISR
and later there is:
.set TIMER0_COMPA_ISR, Default_IRQ
