How to cancel the "login" in Yocto

[zohanlin]

Dear all, I want to make a SD burning image card,

so I need to cancel the login as below:

----------------------------------------------------------------------------------------------------------

NXP i.MX Release Distro 4.9.88-2.0.0 imx6qsabresd ttymxc0

imx6qsabresd login: root
root@imx6qsabresd:~#

----------------------------------------------------------------------------------------------------------

I try to add "/bin/login -f root" to /etc/profile, but it failed because the profile is executed after root login.

Someone could tell me how to cancel "login" ?

Thanks a lot,

zohan

Hi Shivani Patel,

It doesn't work.

I think the reason is our system is used "systemd" to init.

So I modify "ExecStart" in /etc/systemd/system/getty.target.wants/serial-getty@ttymxc0.service,

Ex:  ExecStart=-/sbin/agetty -a root -8 -L %I 115200 $TERM

Thanks,

zohan
