7.3 Configuring the Target aTCA-6200
7.3.1 BIOS Configuration
You can refer to section 6.3.9/6.3.10 to enable Serial Port Console Redirection
7.3.2 Linux GRUB Settings
Linux GRUB supports sending messages to the serial console. The following lines should be added to
the top of the /boot/grub/grub.conf file.
default=1
timeout=5
serial --unit=1 --speed=115200 --word=8 --parity=no --stop=1
terminal --timeout=15 serial console
The following parameters need to be passed to each instance of the linux kernel. They should be
added to the kernel line. It would be helpful if GRUB supported variable substitution so that the
parameters only needed to be defined in one place.
console=tty0 console=ttyS1,115200n8
The example is below:
title SOL (2.6.18-128.el5)
root (hd0,0)
kernel /boot/vmlinuz-2.6.18-128.el5 ro root=LABEL=/ console=tty0
console=ttyS1,115200n8
initrd /boot/initrd-2.6.18-128.el5.img
7.3.3 Linux System Settings
Linux needs to be told to listen for logins on the serial port. This is done by adding the following line
to /etc/inittab.
Add the following line to the init configuration file /etc/inittab.
s1:12345:respawn:/sbin/agetty –L ttyS1 115200 vt100
Now your target aTCA-6200 is ready for SOL connection.
