can not show boot message on screen

Hi all,

Now I am working on i.MX6Q-SDP and want to show boot precess messages on LVDS.

My BSP is L3.0.35_4.1.0 and filesystem is oneiric ubuntu.

Under u-boot I use "console=ttymxc0,115200 console=tty1" but failed.Only the

serial port print messages.Removing "console=ttymxc0,115200" does not help.

How to make is work?

Besides,I want boot linux directly to text mode,not X windows.It not have

grub so I don't know how to do.I have tried disabling lightdm by editing

lightdm.conf,and I was sure it went to text mode because when I typed "reboot"

on the keyboard the board will reboot, but the screen showed nothing.

who can help me?

Any advice will be appreciated!

Best Regards

Xiaoqiang

Hi,

Have you tried to enable a different console? for exmaple :

console=ttymxc0,115200 console=tty2

I tried something similar in our latest BSP and it works.

Yes, I tried tty1 to tty7 but got the same result. Which version are you using?Maybe I should update my BSP.

Thanks a lot.
