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. -- Dave Brown <dbrown03 at harris.com> -----Original Message----- From: Dan Malek [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 02, 2000 6:09 PM To: Brown, David (dbrown03) Cc: linuxppc-embedded at lists.linuxppc.org Subject: Re: Interference between SCC serial and ethernet "Brown, David (dbrown03)" wrote: > > I have the MontaVista 2.2.13 kernel running on my board. 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. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
