Re: [ECOS] ecos - linux driver questions

["Florian Mume" <florian dot mume at web dot de>]

Hi everybody,

thanks a lot for the responses!

I think it will be easier to use uCLinux (although it has a quite large
footprint)
 or write a very simple driver because I intend to use the one card up from
booting.
These "three weeks engineering time" are a little bit much and are probably
the
reason for saving the jobs of experienced engineers ;-)

If somebody has some experience in programming an Orinoco driver, please be
invited to send me a response.
Cheers Florian

Does this also apply to a student doing some project work that will
never leave the lab of his university ? I can understand how the GPL
prevents the integration of linux code into the ecos tree but not how it
could prevent an individual to use linux code into his private project.
