I would like to connect a BeagleBoard-xM to the ArduPilotMega 2560. Connecting over serial appears to me to be the easiest way. I see that in the Arducopter code, Serial2 is not being used. However, tonight I noticed this comment in the optical flow code: "External ADNS3080 OpticalFlow is connected via Serial port 2 (in SPI mode)." I would also like to use optical flow, in addition to the BeagleBoard-xM. Can anyone confirm this comment is true?
If this is the case, how do you suggest that I connect the BeagleBoard-xM and ArduPilotMega so that they can exchange data?
Thanks!

I am building a quadrotor with object tracking feature. all image processing will be done on beaglebone black. can anyone guide me how can i connect beaglebone black with ardupilot mega 2.5 so that beaglebone can give movement commands to ardupilot? also is it posible?
Hi Guys,
Sorry I have been AWOL. I got the connection to work just fine using MAVLink between an app running on the BeagleBoard/PandaBoard and the APM board. Please see section 6 in my attached report for more details.

Hi Noah;
I want to do same thing. So, if you could achieve this please give some information about it.
Thanks

Noah: were you able to connect beaglebone to ardupilot?
I can connect it through UART0 from APM to beaglebone through pin21/22 on beaglebone... but the problem is it doesnt works if i unplug the USB and power the board through battery.
would love to know how you solved the issue.
Hi Noah - were you ever able to exchange data between your BeagleBoard and the APM? I'm a student at Georgia Tech and our group is trying to do something similar. Do you have any suggestions?
Serial 2 cannot be used without changes to the arducopter code. It is put into spi mode in order to communicate with the analog-digital converter on the IMU shield, the data-flash chip, and the optical flow sensor if available. You could connect another device to this port by using a spare digital out on the apm as a chip select line so you only talk to one device at a time.
Students at where I go to college did a similar project with the original BeagleBoard. They just connected it using the usb port on the shield (Serial). It worked fine for them.
