I am using a imx6 based custom board
Made the build system ready using the following guide: https://www.nxp.com/=
docs/en/user-guide/IMX_YOCTO_PROJECT_USERS_GUIDE.pdf

After cloning the yocto source, initialized the build with: DISTRO=3Dfsl-im=
x-fb MACHINE=3Dimx6dlsabresd source imx-setup-release.sh -b build_imx

Then started the build using: bitbake -k core-image-minimal.

The core-image-minimal-xxxx-xxx.tar is generated.=C2=A0 But when the board =
is booted with this RFS image, it did not accept any password for the root =
user.

I checked the local.conf. It has:
EXTRA_IMAGE_FEATURES ?=3D "debug-tweaks"
Yet it did not accept a blank password or any other password.

I had a look at /etc/shadow file.=C2=A0 The root user's password field is e=
mpty.
I tried to change the password manually in /etc/shadow file, but it did not=
 work out.

Can any one point out what should i do to fix the login issue.
