in [Embedded]

From: tamamontu on 10 Feb 2010 00:15 Hi, I am trying to redirect kernel message to serial console. I am trying to modify LCD device driver for cirrus EP9307 board. We are using 2.6.8.1 kernel and reboot as bootloader. I have enabled support for serial console in kernel config using menuconfig. The default console is set to tty0 which is lcd in our case. How can i change this to ttys0(uart1). On net there is some information about changing this using kernel parameters. In our system reboot unzips the kernel image and loads it. ---------------------------------------------------------------------------------------------------------------------------------- + Ethernet eth0: MAC address 00:00:00:00:68:34 IP: 192.168.254.10 0/255.255.255.0, Gateway: 192.168.254.254 Default server: 192.168.254.254, DNS server IP: 192.168.254.254 RedBoot(tm) bootstrap and debug environment [ROMRAM] Non-certified release, version v2_0 - built 10:15:31, Feb 5 2010 Platform: Cirrus Logic EDB9307 Board (ARM920T) Rev A Copyright (C) 2000, 2001, 2002, Red Hat, Inc.
