This task can be performed using DAVE Yocto pre-built package server available at the <code>http://yocto.dave.eu</code> address.

== Installing packages on target (manually) ==

To use <code>opkg</code> at runtime first of all you need to enable the network interface with <code>DNS</code> configuration for accessing external http servers.

Once the network interface is configured, the DAVE's Yocto Lizard package server can be accessed for package downloading:

root@lizard:~# wget http://yocto.dave.eu/~~suce~~lizard/cortexa8hf-vfp-neon-2.6.37.2/<i>pack_name</i>

Where:

* <code>cortexa8hf-vfp-neon-2.6.37.2</code> is the package directory

* <code>http://yocto.dave.eu/~~suce~~lizard</code> is the URL of the webserver

For example:

'''

root@lizard:~# wget http://yocto.dave.eu/~~suce~~lizard/cortexa8hf-vfp-neon-2.6.37.2/openssh-sftp_6.1p1-r0-arago0_cortexa8hf-vfp-neon-2.6.37.2.ipk

For example, for the <code>openssh</code> ~~pakcges reviously~~ packages previously downloaded, you can install the packages on the target with the following command:

<pre>

root@lizard:~#

</pre>

{{ImportantMessage|text=The package dependencies will NOT be resolved automatically.

* openssh-ssh * openssh-keygen * openssh-sshd *

* opkg_install_cmd: Cannot install package openssh.

root@lizard:~#

</pre>

== Installing packages on target (using feed) ==

We need to tell <code>opkg</code> on the embedded system where to look for packages.

The opkg configuration file is /etc/opkg/opkg.conf.

Edit the opkg.conf file to look like this:

<pre>

root@lizard:~# vi /etc/opkg/opkg.conf

# Must have one or more source entries of the form:

#

# src <src-name> <source-url>

#

# and one or more destination entries of the form:

#

# dest <dest-name> <target-path>

#

# where <src-name> and <dest-names> are identifiers that

# should match [a-zA-Z0-9._-]+, <source-url> should be a

# URL that points to a directory containing a Familiar

# Packages file, and <target-path> should be a directory

# that exists on the target system.

</pre>

and add the following server:

src/gz cortexa8hf-vfp-neon http://yocto.dave.eu/lizard/cortexa8hf-vfp-neon-2.6.37.2/

src/gz all http://yocto.dave.eu/lizard/all

root@lizard:~# opkg update
