    Configuring pin 0 (RX) and pin 1 (TX) for serial use in eglibc Linux kernel on Intel Galileo

    Arnoud_Buzing

      I am running the following Linux kernel on the Galileo (the eglibc one, not the uclibc one):

       

      Linux version 3.8.7-yocto-standard (xxx@xxx) (gcc version 4.7.2 (GCC) ) #1 Thu Dec 19 16:43:46 CST 2013

       

      I have a GPS module like this one: http://www.adafruit.com/products/746

       

      This sort of GPS module starts spitting out gps coordinates on a serial connection.

       

      I have connected it the same way I would normally do with an Arduino Uno (+5V goes to VIN, RX to RX, TX to TX, GND to GND).

       

      I have been (unsuccesfully) trying to read from /dev/ttyS0 (and also /dev/ttyS1) until I realized that those may not be the correct serial

      devices to listen on.

       

      Does anyone know  (or is there a way to find out) what the correct device is to listen to serial over pin 0 and 1? Is there perhaps a special Linux boot option that I need to use? Or some special configuration command?

       

      Thanks in advance,

      Arnoud
