Almost everything seems to work but the ethernet. I am using the IP cores that come with the EDK 9.1sp2 ( plb_emac 3.00a + hard_temac 3.00b). The weird thing arises when I try to bring up the interface and use it. If I do "ifconfig eth0 up" the interface shows up but, strangely, it eithers not receives or send packets. I will explain myself, if I assing an IP manually and try to connect to another worksatation within the network ( by pinging from just one of the sides for example ) the interface seems only to send or receive packets , but generallty not both at the same time ( I can see this through the evolution of the Rx/Tx bytes in ifconfig). The only few times that both tx/rx work at the same time is when I do (ifconfig eth0 down and ifconfig eth0 up), but this only works sporadically and only for around a second or less. This is what I get after the first "ifconfig eth0 up": [ 293.258765] eth0: XTemac: Options: 0xb8f2 [ 295.253048] eth0: XTemac: speed set to 10Mb/s [ 295.256042] eth0: XTemac: Send Threshold = 16, Receive Threshold = 2 [ 295.256095] eth0: XTemac: Send Wait bound = 1, Receive Wait bound = 1 [ 297.252047] eth0: XTemac: PHY Link carrier lost.
