I was trying to upgrade the wifi shield firmware as per the instructions provided on http://arduino.cc/en/Hacking/WiFiShieldFirmwareUpgrading

But I am getting the messege as

root@Joms-PC:/home/joms/arduino-1.0.5/hardware/arduino/firmwares/wifishield/scripts#      ./ArduinoWifiShield_upgrade.sh -f all

   Arduino WiFi Shield upgrade
 =========================================
 Instructions:
To access to the USB devices correctly, the dfu-programmer needs to have the root           permissions.

You can upgrade the firmware of the antenna togheter with the shield firmware or only    the shield firmware
if there aren't changes on the antenna firmware.
  Use the '-h' parameter for help
=========================================

How to provide root permission for dfu-programmer which I installed by

sudo apt-get install dfu-programmer

if that is the issue??? Or should I try something else

Answer 1

You need to run the script with sudo:

sudo ./ArduinoWifiShield_upgrade.sh -f all

also you will need to add the path to your Arduino IDE files with the -a switch (it has to be before the -f switch) so:

sudo ./ArduinoWifiShield_upgrade.sh -a PATH/TO/ARDUINO/FILES -f all

replace PATH/TO/ARDUINO/FILES with the path to where you have extracted the Arduino files.
