[Buildroot] buildroot requires a password

[Sabri Altunbas]

Hi folks,

I created a initramfs with buildroot.
I attach my config

It works. But it requires a password which I have not configured and I wanna
have no password.

I investigate in forums and find out 
 
http://buildroot-busybox.2317881.n4.nabble.com/Console-login-root-needing-a-
password-td15155.html

http://buildroot-busybox.2317881.n4.nabble.com/Bug-5366-New-can-t-login-root
-or-default-td30020.html

I followed all recommendations

- taking output/images/rootfs.cpio
-  BR2_PACKAGE_UTIL_LINUX_LOGIN_UTILS not defined

but only the following solution worked

#ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 # GENERIC_SERIAL
ttyS0::respawn:/bin/sh  # GENERIC_SERIAL

overlooked something ?

regards,
s.altunbas

By default, there is no password. Can you share your Buildroot .config
file so we can see if something might be causing problems?

Thanks,

Dear Sabri Altunbas,

Please keep the list in Cc.

This,

together with this cannot work. The Sourcery CodeBench toolchains use
the glibc C library, which simply doesn't work for static linking. Even
if you statically link Busybox, it will still need some of the shared
libraries, loaded dynamically at runtime.

So, switch to use shared libraries, or use a C library that works
properly with static linking: uClibc.

I'll send a patch to ensure that glibc toolchains aren't used when
static linking is selected.

Best regards,

Thomas

Dear Sabri Altunbas,

I believe I asked you to keep the Buildroot list in Cc. Please do it.

See http://buildroot.org/downloads/manual/manual.html#full-rebuild.

I agree. As I said, I'll send a patch to make sure this situation
cannot happen.

Thanks,
