Why am i getting
linaro@cubieboard2:~/Documents/Projects/wiringPi$ sudo ./wiringTest
invalid pin,please check it over.
My code is the following (changed pin 1 to pin 2)
/**
* softPwm test
* author:gootoomoon
* gcc -o test digital.c -lwiringPi -lpthread
*/
#include <stdio.h>
#include <errno.h>
#include <string.h>
#include <wiringPi.h>
#define OUTPUT 1
#define HIGH 1
#define LOW 0
int pin = 2;
int main()
{
if(wiringPiSetupPhys() == -1)
{
fprintf(stdout, "wiring lib init error:%s", strerror(errno));
return 1;
}
pinMode(pin,OUTPUT);
for(;;){
digitalWrite(pin,HIGH);
delay(1000);
digitalWrite(pin,LOW);
delay(1000);
}
}Also, If I use pin 1 based on the diagram, my LED doesn't blink.

What could be the problem?
I was able to compile successfully. Here are some outputs:
linaro@cubieboard2:~/Documents/Projects/wiringPi$ gpio -v
gpio version: 2.00

This Raspberry Pi is a revision 2 board.
However, I am using Cubieboard 2 with Lubuntu.
