Hey, it has been a while since I have messed with this. You can flash it with openwrt without the serial interace. It is helpful to use the serial interface to see what is going on though. I am pretty sure you should be able to telnet in without the serial interface as well. The thing is, if something goes wrong, like you configure the net interface wrong, you won’t be able to access the shell without a serial connection. I think you should be good though.

Was there a step that I missed? After flashing with the image from mightyOhm, isn’t ssh or at least telnet running?

Thanks!

yeah, sorry that EEPROM code is so messy and probably buggy. If you are only comparing against one key, it should be a lot easier. All you need are 2 functions, writecurrentkey and comparecurrentkey. You can just assume that your one key is stored at the first 10 bytes of the EEPROM Something like this I guess:

 
/**
 *  Write the key in 'tag' array into the EEPROM
 */
void storeCurrentKey() {
   for(int i=0; i<CODE_LEN; i++) {
      EEPROM.write(i, tag[i]);
   }
}
 
/**
 * Compare the key currently in 'tag' array with the one we have stored
 */
boolean compareCurrentKey() {
   for(int i=0; i<CODE_LEN; i++) {
      if(EEPROM.read(i) != tag[i]) return false;  // not a match  
   }
   return true;  //if we got here, it must be the same key that is stored
}
