Re: 860T FEC

Hi Tim,

in message [off-list ref] you wrote:

Has anyone had any luck with the 860T FEC driver in the 2.4 kernel (I am

was ever working properly. Is anyone running it that can refute this? I

I think you are right. This code cannot work, never could.

But the good news is that I have a working version of the FEC driver;
see our modified kernel sources in
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/,
or the patch at
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/patches/patch.8xx_misc
(and the README for it in
ftp://ftp.denx.de/pub/LinuxPPC/usr/src/patches/README.8xx_misc
).

BTW: I've sent all these patches to Dan and Cort and Ben, so  I  hope
at least part of it will make it in the official sources.

have made some changes that seem to get it halfway there, but am not
getting any transmit interrupts yet (I am getting receive and mii
interrupts).

It's working for me in several configurations.

Thanks! I finally got it up and running, and have ethernet!!!. I had to
make some changes WRT some of the MII commands, which I don't think
would impact anyone else, but I also had to change the order of setting
the fecp->imask, and clearing the interrupts. The patch had it clearing
the interrupts, then setting the mask. It needed to be the otherway
around, at least for me.

Cheers,
tim
