Smallest image possible that does something (but not much) is most likely
around 512Kb.

It varies depending on how big your image can be,  if you can do XIP
for the kernel and fielsystem,  the list goes on.

It has been discussed many times on the list before,  look through the
uClinux-dev archives.

> Any information regarding uClinux porting to Atmel processors will be highly appreciable.

To get good feedback on what is possible you need to tell us what you
are trying to do.

The size of the image and resource usage depends on:

	What drivers you need
	What apps you need
	networking ? how much networking ?
	fileystems
	hot plug (usb etc)
	how much you can put in flash

The list goes on,  so the question,  how small can I make it, is a bit
like asking how long is a piece of string :-)

Cheers,
