Hi,

It is first time for me to post on this mailing list.
I have a question about Beagleboard’s console.
I’d like to ask about how to change console from ttyS2 to ttyS1.

I tried following two means, but didn’t work.

  1. In u-boot console, change environment variable.
    setenv console ttyS1,115200n8

  2. Change include/configs/omap3_beagle.h as following.

Hi there,

If you are simply trying to change the console (that don’t include printk messages)

simply go to the ext3 partition on the sd card go into folder /etc/
open “inittab” file into text editor of your choice

line 31 on my beagle board “respawn:/sbin/getty 115200 ttyS2”

change the console login from ttyS2 to ttyS1.

next time when you boot up the beagle board, it will put the console to ttyS1

Hope this helps

Thanks
