SCC and SMC Implementation

SCC and SMC Implementation

[Bernal, Fernando J]

I would like to know if someone has implemented the two SMC and the two SCC
serial ports on an embedded 823 PowerPC.

F.J.,

SNMC has implement both SMC and SCC serial drivers for the MPC850.  The drivers

seem to work for the MPC823 as well, although we have not done extensive
testing
for the 823.

You can download the sources from ftp.qslinux.org (documentation on
www.qslinux.org).

The drivers can be found in the directory snmc/qslinux/drivers/char.

Regards,
Daris Nevil

I have a MPC860 system which works with serial ports  on  both  SMC's
and  all  4  SCC's. I think it should work on 823 and 850 as well (at
least the SMC part is tested).

Which kernel version do you need, 2.2.x or 2.4.x?

It's part of the standard kernel release.  I think I finally got
the I/O pin configuration right in the upcoming 2.4 release.  You
may need to manually edit the configuration table in
arch/ppc/8xx_io/uart.c to get the configuration you desire.  It seems
everyone has a different configuration desire that is difficult to
implement in the standard configuration scripts (maybe the upcoming
CML2 will help this).

FYI, the 823 does not have two SCCs, only the 823e does.
