We are using GNAT Pro cross compiler with Yokto and Debian, though I 
presume it will work with any distribution.

You need no evaluation. Simply install Debian, Ubuntu or Fedora on a 
resonable ARM board 2GB or more. Use the native GNAT FSF compiler there 
to build your executable. Transfer it to the target board. Enjoy.

Once you are ready, go and buy GNAT Pro.
