Daan,

   Got it to work. Certainly was the version of the NFS service that came 
with my Cento OS distro.

Thanks for your help!
Andy

OMAP networking app

[Abot Botbot]

Hello all,

   I'm slated to develop an application that sends and recieves UDP packets 
over the ethernet port of the OMAP5912 EVM board from spectrum digital. Does 
anyone have a decent document pertaining to this process, and better yet, a 
working application that could help guide my development there-in? Any help 
you can offer will be greatly appreciated.

Thanks,
Andy

once u have linux up, you can do what you would do on a PC/anywhere
else. Linux application interface remains the same... so any standard
network textbook can be a guide here... So the correct question would be
do you have a linux port for 5912? The answer to my knowledge is "yes".
