D for Raspberry, Toradex-T20, Android

[erkki]

Hi!

I work with Angstrom Linux on ARM. Later I may have to develop software for
other ARM platforms running Linux. Personally I'm also looking forward to
receiving my Raspberry (another Linux-on-ARM) board for hobby projects.

What options do I have if I want to use D2 with these?
And, is there something unexpected that I should know?

Thanks in advance!
