sorry, I missed that mail. Did Gedare or Joel respond to it? Can you
please add your name to the list here:

There are really few peripherals left on BBB. Someone already added a
GPIO driver some time back. I don't think anything has been done
regarding ADC. But on the other hand we don't really have an abstraction
layer for that in RTEMS. Depending on what you plan to add it can be
anything from not useful at all to a nice part of a project. But you
have to create some convincing suggestion ;-)

No problem. Don't hesitate to ask if you are stuck somewhere.

Best regards

Christian
