declaimed the following:

>I have looked at the Ada Drivers Library, and tried to work with it, though I have not had much luck. I think that I don't understand the difference between the board support packages and the drivers well enough, and where I need to be building things to access the required libraries to make much progress.
>I think that Adacore choosing to support the microbit is a good idea. The microbit gives a lot of choices for how to interact with it. You can start with micropython and go on to other programming languages from there. 
>Trying to understand a topic/learn something new from a distance without any experience or guidance can lead to trouble. Picking where to start is the most difficult part, every path seems equal when you know nothing. 
>The advice from Dmitry seems to have been very wise and I have been able to find some really good information to get be started with either the Beaglebone Black or the Raspberry Pi. The Exploring Beaglebone Black book by Derek Molloy seems to be exactly the sort of resource that I have been looking for (there is no Ada programming, but I can add that in later with a bit of luck). There is enough information about the background Linux environment to get me started. 

	Problem is that Molloy is from the era of Debian Wheezy and kernel
(run-time) Device Tree loading and the "Cape Manager"... Jessie saw the
transition to using u-Boot Device Tree loading and removal of the Cape
Manager... And Stretch has just taken that further... Pretty much anything
to do with device trees and pin-muxing has changed. And some of what I've
read implies that even the sysfs method of accessing GPIO and other
peripherals will be changing.
