Notes de mise en route
"Quick Start Guide", Section 11

If you want to use WiFi, you must follow these steps. The WiFi driver is not present in   the Linux image in SPI flash because it is too large. The Linux SD image also includes ALSA, V4L2, python, SSH, node.js, and openCV.

Linux Python script from Arduino sketch /* This example uses Linux system calls to create a python script which writes number 0-9 to a file, log.txt, one number per second. Then execute the python script in the background, and regularly read the contents of the logfile in the sketch while the python script is updating it.

char output[3];

void setup { Serial.begin(115200); system("echo '#!/usr/bin/python' > myScript.py"); system("echo 'import time' >> myScript.py"); system("echo 'for i in range(10):' >> myScript.py"); system("echo '   with open(\"log.txt\", \"w\") as fh:' >> myScript.py"); system("echo '       fh.write(\"{0}\".format(i))' >> myScript.py"); system("echo '   time.sleep(1)' >> myScript.py"); system("chmod a+x myScript.py"); system("./myScript.py &"); }

void loop { FILE *fp; fp = fopen("log.txt", "r"); fgets(output, 2, fp); fclose(fp); Serial.println(output); delay(1000); }

void setup { system("telnetd -l /bin/sh"); }

void loop { system("ifconfig eth0 > /dev/ttyGS0"); sleep(20); }

Accès SSH
Par defaut, la distribution fournie n'inclut pas de serveur SSH.

Pour y remedier, Intel met a disposition une image plus complete qui entre autre, en possède un: https://communities.intel.com/docs/DOC-22226 (LINUX IMAGE FOR SD for Intel Galileo)

Une fois telechargé, voir la section 11 du document "Quick Start Guide" pour mettre cette image sur une micro-SD.

Après avoir récupérer l'adresse IP via le programme décrit dans la section précédente, faire simplement un ssh root@adresse_ip pour se connecter a la carte
