Re: [ECOS] i386 questions

[Mike Friedrichs <mike_fr1 at lcc dot net>]

does a 'linux synthetic target' mean that an ecos application will run
on top of x86 linux. probably sounds elementary but the explanation is
helpful.

if this is the case what is being gained. it seems one of the advantages
that ecos has is the small foot print for its os, but when you put on
top of linux you are back to a very large foot print. the smallest linux
embedded foot print that i've found still needs 2-8 meg of ram.

thanks again
