RE: Interference between SCC serial and ethernet

Okay, since SCC serial and ethernet are known to work simultaneously, I'll
be looking for problems in my board configuration or in the board itself.
We have used the board for a few years, the Ethernet portion is being
exercised for the first time by me.

I'm not expecting help on this .. it's the kind of problem that's hard to
diagnose/debug over a mailing list.  I boot up with root=/dev/ram ip=...,
and Ethernet gets setup and enabled at boot.  Then I use the SCC serial
ports, and they work fine.  Then I ping the board over Ethernet, and the SCC
serial ports don't work anymore.

If I do find software problems in the kernel, I'll certainly report them,
but I'm now expecting to find something wrong with the board or something
wrong with my configuration.

I need a little help here :-).....I assume it is a 860 class processor,
but what about the board?  There are implementation specific considerations
for the I/O port configurations.  You didn't happen to use some of
the I/O ports for Ethernet control that multiplex to the others?

The SCC serial ports work fine for me, until I use Ethernet.

How do you boot the system not using Ethernet, then enable it?  Do
you mean running to different kernel configurations?

... Has anyone used SCC serial ports and SCC Ethernet simultaneously?

Yes, even multiple Ethernet and multiple SCCs.
