FEC, and am now working on the kernel. At the moment, I'm using the 2.4-2000-11-11 kernel from ftp.denx.de as a baseline, since itThis version of the kernel is derived from 2.4.0-test5 from July, 26.
OK. Is there a newer one that's also friendly to 860Ts? Some others appeared somewhat different configuration-wise. What base do you use?
I have run into the same problem, and my suggestion is to try the version of fec.c I'll attach below (I've sent this to Dan Malek some days ago, but haven't heard anything since).
I did, and it seems to work great. It negotiated a 100Mbps half-duplex after detecting the PHYs, and took off from there with NFS. I did need to hook up the interrupt line from the 972, as you indicated. Next week, I guess I'll be doing a CVS merge from your latest ppcboot tree and see if I can get that FEC code to play.
