Support for multiple consoles

Support for multiple consoles

[Michael Carey]

Hi All,

I am using ELDK 3.1.1 on a mpc5200 platform with a CoralP pci card.  I =
also connecting a keyboard and mouse.  When I compile the code without a =
virtual console, then my terminal session rules.  I can type with my =
terminal keyboard and everything seems fine.

When I compile with a virtual console, then my embedded lcd displays text =
and my usb keyboard works.  Everything is great.

Is there a way to switch back and forth between my embedded console to my =
terminal console?  I have tried console=3DttyS0, but that does not seem to =
do anything.
When I list my devices: 'ls /dev' I only get tty, ttyS0, ttyS1, and ttyS2. =
 I do not see a tty0.

Is there a way to run multiple consoles on this configuration? If not, =
does to ELDK 4.x support this?


Thanks in advance for any information or guidance.

Michael Carey

You should be able to get both consoles working. You probably aren't
running a login process on the second console. I haven't done this
recently, but reading about getty should give you some clues. This
used to be controled through inittab but inittab is gone on my desktop
so I don't know what controls it anymore.
