There are ARM-Cortex development boards with a bit more resources, and 
Ada support including (Ravenscar) tasking, either bare-bones or over a 
small RTOS.

Look for work by Simon Wright in respect of these. 

Much simpler than Beaglebone, but not full Linux. 

Interfacing to hardware isn't difficult. Generally you abstract the 
hardware level into a package which knows where the register addresses 
are, and different (related) targets use different implementations of the 
packages.

For full Linux, I'd look at the Raspberry Pi. But then you get involved 
in writing device drivers - there's a project on the first steps on 
writing Linux device drivers in Ada, but it's more complex, and not as 
well trodden as Linux device drivers in C.
