QuickstartTo get you started, I suggest you use this Debian image on your U2 for running BOINC:
It's very similar to that of the Raspbian build which makes life easier for us when attaching projects.
You'll need an 8GB MicroSD card for it to fit. I suggest getting a class 10. Either use dd or your favourite image loader to push it to the SD card.
Some additional things you'll need to do after loading the image is configure your timezone and locale.
For getting BOINC going, you can follow the same instructions for attaching project binaries as at http://burdeview.blogspot.com.au/p/raspberry-pi-boinc-project-ive-created.html#quickstart
More to come....
