The user has to enter the password for the root user twice.

The system is also required to have at least a single non-root user. The
adduser

command has been used to add another user. This is

friendlier front end than the useradd command, choosing Debian policy
conformant UID and GID values, creating a home directory with skeletal
configuration, running a custom script, and other features.

adduser admin

where:

admin

– is the new username

This command automatically asks for the username’s password twice
and some information. The other information is optional. For this
system, the password given for the admin user is admin.

2.4 Driver Installation

2.4.1 Video for Linux 2

The Video4Linux (V4L) included in MontaVista version 3.0 Kernel should
be updated since the camera driver uses Video4Linux 2 (V4L2) module.
V4L2 can be downloaded from http://www.thedirks.org/v4l2/.

To update the Video4Linux module, go to the exploded path of the
/usr/src/videodevX

directory and run make. If this command

outputs an error saying that the kernel has no support for loadable
modules, go to /usr/src/linux, make sure the support for the
loadable module is enabled, and save the configuration. Now return to
the exploded path of the V4L2 module and run make again. This should
proceed with the compilation and then make install can then be
issued. This command renames the old V4L modules and updates it
with the new videodevX.o and v4l_compat.o modules. The header
file /usr/include/linux/videodev.h is overwritten with the new
one. To test if the installation is successful, run modprobe videodevX
to insert the module to the kernel. The module should be listed if lsmod
command is issued.

To load the V4L2 modules during start up, append the videodevX line
in /etc/modules file.
