The other pins are assigned to JTAG by default.
Either turn off the JTAG fuse (but then, you could not use JTAG
for programming anymore either), or dynamically disable it
I have a simple program for ATmega324PA:
#include
#define F_CPU 2000UL
#include
int main (void) {
DDRA = 0xFF;
while (1) {
_delay_ms (1);
PORTA = 0X00;
_delay_ms (1);
PORTA = 0XFF;
}
that on Port A works perfectly and generates a square wave on all pins.
