Hi Ulrich,

Sorry, not yet. But in general a very simple system should be well
running, as long as you only need 1-2 threads and the i2c driver.

Very likely you'll only need to add the Mega644 to the config files and
perhaps check for some conditional compilation in the AVR drivers.

In general, what's the problem with Nut/OS on Ubuntu 13.10?

No sorry. But on the AVR you could try to easily hand-craft the driver
completely without any OS at all.

If you need any support, please send me a private mail or give me a call
