I'm a bit late to the party, but wanted to say thanks for this resource.  It really helped me get started working on my SAML21 (cortex m0+).  

One minor comment:
In the sections where you start showing gcc commands, you might consider making another note about the RTS here or perhaps another example.  When I was going through the examples using the arm-eabi-gcc commands and such, I immediately started hitting errors about not having system.ads.  It took me a bit to realize this was because GNAT GPL 2015 doesn't come with a default RTS for the arm-eabi cross compiler calls so you have to specify an RTS (which none of the examples address directly).  I know you mentioned needing an RTS in the first section, but for someone new, knowing this is where you might be specify it for the cross compiler would be useful.  If you are compiling native, I realize this isn't an issue, but wanted to toss that out there for the cross compile folks.

Anyways, thank you for the amazing work.
