So the real question is: how big is the Flash ROM, and how much memory does the .text part of RIOT consume on 8-bit platforms. For our hello-world application this is 8524 bytes on the Arduino Mega 2560, for the somewhat more sophisticated default application it's ~15 KiB (without any network support). @Sudarshan is that remotely in the flash sizes of the Arduino Uno?
