BeagleBoard with Arduino
Getting the Arduino working on the BeagleBoard or BeagleBoard xM (Probably applies to the PandaBoard and similar platforms)
For recent Arduinos based on the Atmel USB chip (like the Arduino Uno) you will need to install the cdc-acm driver. You can do this in Angstrom using the following command:
opkg install kernel-module-cdc-acm
Your Arduino should then appear in /dev under the name ttyACM0 (note that the name is not the same as in OSX where it shows as tty.usbmodemXXXX)
For older Arduinos based on the FTDI chip, this is the driver to install :
opkg install kernel-module-ftdi-sio
I have not tested this so I am not sure under what name it will show up...
Thanks for prpplague for helping me sorting this out !
