Mobile Apps - Ethernet renew time

Asked By Jürgen Thomaß

20-Nov-09 07:49 AM

Hello.

I have post this questions some time ago but I have recived no answers.

I have a board with an iMX31 CPU and an SMSC Ethernet controller running
with
WinCE5.0.
Is it possible to change the time too detect the insertion of the ethernet
cable. In the actual configuration it takes about 10 sec too detect the
cable. When I press RENEW it takes less than 1 sec. Is there a registry key
for the scanning period or is it a driver problem.

Best regards

Jürgen

I'd say 'driver problem' is the first to check.  it is probably waiting to
make sure that the connection is not intermittent before it notifies the
network stack that the cable has been connected.  If it is actually the
network stack causing the delay, I am pretty sure there is no adjustable
setting to change how long the detection and address request process takes.

Hello.

Here are the debugmsg:
After disconnect the cable following msg displayed:

0x87da0400: LanSetInterfaceLinkStatus(00172D30/001734A0) - 0 0
0x87da0400: SetInterfaceLinkStatus(IF 6) -> disconnected

and then, after 10 sec the following msg displayed and the icon is changed
too disconnect:

I think the driver is not the problem, because the disconnection is detect
immediately.
Is there a way to speed up the detection time in the network stack?

Thanks

Those are the debug messages for the wrong case.  You want to quickly detect
*connect*, not disconnect, right?  Although the relative times at which those
operations occur is interesting, I do not think that you can generalize from
the disconnect case to the connect case and there might  be useful
information in the connect case.  If the connect case is the same, you are out
of luck unless you have the NDIS source and can read through it and see
what is causing the delay.
