[lwip-users] Communication (timeout) Problem WinXP/Win7 with LwIP

[sb80]

Hello,

I have a PC application that runs under Win7 and WinXP and communicate with
a device (Hilscher NetX500) which use the rtX OS (from Hilscher) with the
LwIP (Version see below). The device has two ethernet interfaces. On the
device runs a client (for RDT) on eth0 and the PC application use also the
eth0 to commuicate with the device. My problem is, that i can't establish a
connection with the PC application if there are running under WinXP, but if
i use the same PC application with Win7 it works (same configurations like
WinXP). 

I debugged the LwIp and i got the debuginformation (extract) in the two
attached files.

I think i get a timeout problem, because of lost packets (retransmission
based on collisions) if i use the PC application on WinXP. But i don't know
why Win7 don't make the same problem like WinXP.

I hope anybody undestand my problem and have a idea.

LwIP Version?? Is this Vers. 1.0.1 ???

#define LWIPTASK_MAJOR_VERSION       (1)
/** minor task version */
#define LWIPTASK_MINOR_VERSION       (0)
/** API version */
#define LWIPTASK_API_VERSION         (1)


Thanks

stefan
