RE: [ECOS] waiting for proposal. (TCP/IP stack used in ARM E7T board) Thanks a lot! ( Can I control the ethernet driver directly? I want to send out some testing ethernet frame instead of the IP package)

["jameshq" <jameshq at liverpool dot ac dot uk>]

Thanks for your reply. but unfortunately the whole system doesn't work. the
following is the example code I use for testing:

What I am trying to do is: try to luminize the the LED to "1" on the ARM E7T
board at the beginning of the program. and try to change it to "3" when a
connection from remote computer comes.  Is there any possible way for me to
control the ethernet driver directly (for testing, just want to send some
ethernet frame out onto the ethernet link)? any ethernet driver functions I
can use in the app? Thanks a lot!

You could try pinging the board for start...if that works then you can go on
to test it further...make sure you configured valid IP address and gateway
address
for it in the configtool.Put it in your local network (same netmask etc)
