Re: SCC3 console problem on MPC860

In message [ref] you wrote:

I had problems trying to get the uart.c driver to do what you wanted as

drivers, making one work just for the SCC, and the other only for the
SMC.  This works quite well.

This is really not needed.

We have tested the normal uart driver in a setup running on 5  serial
ports  (2  x  SMC, 3 x SCC, with Ethernet of the 4th SCC). No serious
load tests so  far,  but  basic  I/O  functions  worked  without  any
problems.

The code is in the QSLinux release, which you can download from
ftp:://qslinux.org.  When you untar the kernel you can find the two
drivers in the directory snmc/qslinux/kernel/drivers/char.

Ummm... AFAIK QSLinux is based on a 2.2.5  kernel?  That's  _awfully_
old.  I  can  imagine  that there were lots of problems with the uart
driver at this time. And other bugs as well.
