As everyone knows, Arduino IDE can not ever run on Maemo due to a dependency on Sun Java.

However I've seen some links (here?) describing how you can host avrdude on Maemo, and compile code for the Arduino.


There's a third item of interest I'll point out:
Using an N800 to "upload" an Arduino sketch which was previously compiled. (So like if you compiled "blink", and copied it onto a SD card, which you could then upload to the Arduino).

Someone's already managed to turn an Arduino in-to an Arduino uploader. (The host Arduino isn't compiling anything, it just acts like a jukebox or selection interface for the target Arduino). Someone did the hard work of figuiring out the bootloader protocol, so it could be adapted to another platform like a Maemo device.

That project is called "Boot Drive": http://baldwisdom.com/bootdrive/

(As an example how it is useful, lets say you had 6 or so interesting Arduino sketches. The Arduino only holds one sketch, but you could use the n800 to upload and alternate between each sketch, no laptop required).
