To use <code>opkg</code> at runtime first of all you need to enable a channel, which commonly is a remote webserver that provide packages feed and the binary packages itself
  
 
An example of network interface configuration for Internet access is described here below. Configuration can be done directly on serial console with the following commands:

Introduction[edit | edit source]

Thanks to the opkg packet manager installed on Yocto built root file system, Lizard module allows to install new packages (if available).

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

Installing packages on target[edit | edit source]

To use opkg at runtime first of all you need to enable a channel, which commonly is a remote webserver that provide packages feed and the binary packages itself

An example of network interface configuration for Internet access is described here below. Configuration can be done directly on serial console with the following commands: 

root@sbc-lynx:~# ifconfig eth0 192.168.0.94
root@sbc-lynx:~# route add default gw 192.168.0.254
root@sbc-lynx:~# echo "nameserver 8.8.8.8" > /etc/resolv.conf

where 192.168.0.254 is the gateway address and 8.8.8.8 is the DNS server (in this case Google's one).

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

On the target edit the opkg configuration file to tell opkg where to look for packages.

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

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.

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
