1) Connect both USB mini-B type cables to the gumstix board (OTG and console ports)
2) Open a serial console, 115200 baud
dmesg | grep tty # should see the name serial port at the end screen /dev/ttyUSB0 115200
3) Ensure both antennas are connected. Long antenna is for the 868MHz XBee, short antenna for the 5.8GHz video transmitter. Connect battery to quadrotor and power plug to gumstix. Turn on the flight computer to enable the low battery alarm.
A number of messages should appear in the serial console as the gumstix boots up before the login page eventually appears. Login information is josh/hovergroup.
4) Enable the usb-networking interface over the OTG port
sudo modprobe g_ether
At this point a new network interface should appear on your computer. Share your internet connection with this new interface, then on the vehicle:
dhclient usb0 ifconfig usb0
If the gumstix successfully acquired an IP address then you should be able to ssh in from the host computer.
ssh josh@10.42.0.83
You can also check that the vehicle has internet access by pinging some public IP. Alternatively if internet is not required, the interfaces can both be configured to static addresses on the same subnet.
