Hi all i'm actually trying to use a LXT971 on a arm rm9200 based based board so i'm using the at91r9200dk_config to compile the sources i've just changed the dm9161.c and dm9161.h files to match the good register (dm9161.h contents is replaced by the one of lxt971a.h). I've put these two files in the mail So the PHY component is well detected, so as the connection properties (10/100 Half/Full-Duplex) but when i try to ping a foreign device (i've activate the ping function) or if i try to use tftp to download file, nothing is happening (no connection on the tftp server are detected)

So does anybody have an idea about how to make the network component working?
