Hi,

I'm a newbie to the ADA world, and I'd like to set up an ADA development 
environment for Atmel AVR MCUs under Windows.

This is not an easy task, because I found very few documentation about 
using ADA on AVR. I'd like to get advices and/or links to existing 
documentation or projects.

First of all, about the the compiler itself, it seems to exist two options :
- AVR-ADA (there is some documentation, but the project does not seem to 
be updated)
- Libre AVR compiler from Adacore (no documentation found !)
Which one would be the best choice ?

Now, about the development environment, I'm running under Windows. I'd 
like to have :
- A visual source editor with source highlighting. Libre version of 
Adacore GPS does the job. I enjoy Eclipse, but ADA plugin seems to be 
only available on adacore commercial versions.
- A graphical source-level debugging, with the following basic features :
   - Browsing assembly code, mixed with inline ADA source code
   - Setting breakpoints and watches graphically
   - Reading variable content in a window during a breakpoint

My first approach was to try Atmel AVR Studio for source-level 
debugging. Generating an ELF or COFF file, with the corresponding symbol 
table and source code, and importing it in AVR Studio, should do the 
job. Anyway, I did not have much success (yet). AVR Studio does not seem 
to "see" the symbol table, and I did not manage to get a correct view of 
ADA source code mixed with the resulting assembly code.

Another option may be to use GPS for graphical debugging, associated 
with GDB. I have a compatible hardware JTAG/ISP/DebugWire probe (Atmel 
JTAGICE3), but I did not investigate yet. I don't know if GPS/GDB 
debugger would work for AVR target.

Thank you in advance for your help and suggestions. Kind regards.
