Building firmware with gcc

[tormod]

@dnordenberg

Congratulations to your great work tormod! (and everyone else who helped on this)

Does it really run perfectly on the first try or is there a lots of smaller bugs? Do you notice any compiler improvements like faster code or bootup? I hope open source is better but on the other hand IAR is highly specialized and been in the game for a long time too.

AFAICS, it works perfectly. I have not tested for instance SD cards though. But I think it is pretty much everything works or nothing works in this game. For compiler improvements I think there is no appreciable difference. The gcc bin files are larger than the IAR bin files, but OTOH there is no code size limitation with gcc. If you want faster boot, just comment out the Delayms(2000) in the splash screen The most important is that anyone now can now build (and install) the firmware with free software tools, on any platform.
