[Buildroot] How to Login in a filesystem as a root

[amr ali]

Hi,
I managed to build filesystem for my davinci DVM6446 board. I want to login as root instead of the default user.
How can I do that?
One more thing, how can I test webkit installed in my filesystem?

By default, embedded Linux systems generated by Buildroot have a 'root'
account, for which the password is empty. So at the log-in prompt, just
use 'root', and you're all set.

We have a Webkit package, so just enable it in the configuration.
However, the Webkit package hasn't been updated since a while, and it
may not build properly. I know Lionel Landwerlin has posted some
patches to upgrade it, but they haven't been merged so far.

Amr Ali, is it possible that your DaVinci board isn't running
something generated by "buildroot"?  Or perhaps it's based on
buildroot, but it's been customised to have a password for root?

I'm wondering if it's really based on buildroot, as even if the root
password has been set (I do for my buildroot-based product), it should
still allow console logins for the root user.

Mitch.

I checked the passwd and shadow files, they have a root user but whenever I type root at login it give invalid login.
May be you are right. I need to read more about buildroot. I can send you my configuration files if possible to check it yourself.

[Buildroot] How to Login in a filesystem as a root

[Paul Jones]

I've had this problem a few times before. It seems to happen if the kernel
and rootfs are built with different toolchains (even the same version) that
have different options for things like wchar. I never did figure it out but
the issue seems to have gone away for now.

Hi,
does the busybox binary on your target board belong to root?

I've had that issue once, that I managed to create it with an other owner as 
user.

Moreover I'm not sure if it might need the suid-bit set.

Do you have a file on your DaVinci called "/etc/securetty"?  If so,
what's in it?
