Writing/Reading GPIO on AT91SAM9260ek

["Paul Kavan" <pkavan@xxxxxxxxx>]

#include <asm/arch/gpio.h>
#include <stdio.h>

int main(void)
{
   int pin_val;
   while(1){

     pin_val = at91_get_gpio_value(AT91_PIN_PA30);
     printf("Pin Value = %d\n", pin_val);
   }
}


I get some error statements upon compile like:

grhuser@pcL7:$ arm-linux-gcc -o buttontest button_test2.c
In file included from button_test2.c:1:

I am not sure what to do with this? Anyone had success with making the
gpio work with the get/set calls?

Thanks

Paul
