From mboxrd@z Thu Jan 1 00:00:00 1970 Message-Id: Date: Wed, 26 Mar 2003 16:21:25 -0600 From: "Chuck Partridge" To: Cc: "<" Subject: RE: SCC2 and SCC3 serial ports on RPX Classic (MPC860) Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Sender: owner-linuxppc-embedded@lists.linuxppc.org List-Id: Is this string sent by a program loaded via insmod and busybox? I had a problem with drivers loaded as modules when using busybox. The wrong strings would be sent when I did printk. It drove me nuts for days. I installed the true version of insmod and all worked fine. Maybe it helps, Chuck >>> 03/26/03 04:11PM >>> Wolfgang, What I mean by "not random" is this: I write a string to /dev/tts/1, which will cause another string to be printed on the remote console. If I repeat this 50 times, the same messed up string will appear. Thanks. I hope that answers the question. --Dima >In message >n.com> you wrote: >> >> I compiled the 2.4.7 kernel (from TimeSYS) with SCC2 and >SCC3 enabled for IO.
