Hello,

You will be able to work with eCos on LPC2104, but it is far from an 
ideal sollution. You have to make restictions for thread stack sizes, 
make a minimal configuration and you won't be able to use more than 2 
or 3 threads. For an example my simple application that using 2 
threads with 2048byte stack size (and of course with stack for idle 
thread, and separate stack for ITs) uses about 20k of RAM so you 
should make resticions for stack sizes above. 

I'm not familiar with the JFFS2 file sytem so I'm unable to say 
something about its resource requiments.
