Re: 8xx SMC1 problem

In message [ref] you wrote:
First of, I have three serial ports (SMC1, SMC2 and SCC3) and they all work
 fine when the console is on SMC1. I have gadgets connected to SMC2 and SCC
3 and now I need SMC1 for yet another device. So I have undefined CONFIG_SE
RIAL_CONSOLE in the kernel config and I jump out of u-boot (which have the
console on SMC1) with the argument "console=none".
And did you make sure that no other process is accessing ttyS0 ?
When logging in (via telnet) ttyS0 works no more (but S1 and S2 does). At r
andom bootups, it is possible to open the port but it is no good for read o
r write.

Can anybody give me some advise on how to enable SMC1 but at the same time
don't have a console on it?
We did the same (passing console=null) in a couple of  configurations
and  had  no  problems  using SMC1 as standard serial port. Try *not*
undefining CONFIG_SERIAL_CONSOLE.

And please keep your line length < 72 characters or so.

Best regards,
