Subject: Using SMC on MPC8272 based board
Date: Wed, 09 Nov 2005 09:28:19 +0200 [thread overview]
Message-ID: <4371A513.6040409@compulab.co.il> (raw)
I have a custom board based on MPC8272 and I don't succeed to enable SMC
serial port. I'm running Linux 2.6.12.3 with CPM serial drivers from
2.6.13.2.
When I configure the kernel to use one or two SCCs, with or without
serial console everything works fine. But if I configure the kernel to
support SMC serial port, I see nothing at the SMC port.
I've noticed that SMC1 pins are configured at port D (as in MPC8260),
but MPC8272 has the SMC1 on the port C. I've changed the pins assignment
to use the port C pins, but it didn't help.
When I enable support for serial console on SCC/SMC port, the system
hangs when the SMC is enabled.
When I don't enable support for serial console on SCC/SMC port, the
system boots OK, but there's nothing on the SMC port.
