Hello, I work on several custom 82xx boards with Linux 2.4 and 2.6.
I have ported Linux 2.6.9 on different boards and I noticed that I have tx carrier errors on my FCC ports. Almost one error per xmit. I reinstalled Linux 2.4.18 on these boards and I have NO ERROR. The errors arise with PHY configured in 100M full duplex (or autoneg). The FCC has the same duplex as PHY. I found on web another mail concerning a problem on PQ2FADS Linux2.6.8 when mounting a NFS. The writer has also noticed that he has tx carrier errors but the mail focused on mount and not FCC. > # ifconfig > eth0 Link encap:Ethernet HWaddr 08:00:17:40:00:03 > inet addr:192.168.0.5 Bcast:192.168.0.255 Mask:255.255.255.0 > UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 > RX packets:122 errors:0 dropped:0 overruns:0 frame:0 > TX packets:114 errors:0 dropped:0 overruns:0 carrier:114 > collisions:0 txqueuelen:1000 > RX bytes:20747 (20.2 kb) TX bytes:14320 (13.9 kb) > Base address:0x8500 I think this is not a phy or hardware problem but rather a FCC configuration mismatch in fcc_enet.c. Thanks for any tips Laurent
