Attiny2313 C program with function

Hello!

I am trying to program attiny2313 using avr-gcc.
The program:

#include <avr/io.h>

int subfunc(volatile uint8_t *port, uint8_t mask) {
*port |= mask;
return 0;
}

int main() {
subfunc(&PORTB,0xff);
return 0;
}


I am using avr-gcc (on Ubuntu 6.06 linux) but the program doesn't work. It seems to get stuck in subfunction.

Any ideas what I am doing wrong.

To mask off a bit don't use a function use a macro. a lot easier. AS far as you code I thing the & in the call is messing you up. try getting ride of it
