[U-Boot-Users] Serial console for Linux at SCC1?

Hi there,

on my MPC8xx board I use SMC1 as serial console for U-Boot and Linux.

I start linux using these bootargs

setenv bootargs root=/dev/mtdblock0 rw console=ttyS0

Linux tells me
CPM UART driver version 0.04
ttyS0 on SMC1 at 0x0280, BRG1
ttyS1 on SMC2 at 0x0380, BRG2
ttyS2 on SCC1 at 0x0000, BRG3

Everything is fine.
Now I just wanted to set bootargs to "root=/dev/mtdblock0 rw console=ttyS2"
in order to get a Linux console at a different Port.
But it's not working, i.e. I can't see any messages at ttyS2.

Could it be that since I configured U-Boot to use SMC for console, it's not going work
with SCC anyway?
