If you want to run Ada on a bare-metal embedded system try GNATforAVR32. I =
ported GNAT to the Atmel AVR32 architecture and a Ravenscar bare-board run-=
time enviroment to the AVR32 UC3 microcontroller series as a part of my PhD=
 at NTNU.

I have not had time to work on the system after finishing my PhD, but it wo=
rks very well on the UC3A series, and can be updated to newer parts without=
 much effort.
