13 Application Installation and Usage
13.1 Introduction
For updating and upgrading software on the mvBlueLYNX-X, MATRIX VISION uses Opkg, a lightweight
package management system based on Ipkg. Applications, tools, etc. are available as
.ipk
files (packages) in
a customer feed published online on the MATRIX VISION website. It is possible to create your own feed,
however, we recommend the stable customer feed on our website.
By default
, the Opkg configuration files are set to this stable feed on our website:
http://beta.matrix-vision.com/mvblx-feed/stable/
.
•
13.1.1 Changing the feed location
To change the feed the mvBlueLYNX-X should use, you have to set the config files in the
/etc/opkg/
folder:
matrix@mvblx:~$ ls -l /etc/opkg/
total 40
-rw-r--r-- 1 root root 151 Jul 5 08:08 arch.conf
-rw-r--r-- 1 root root 82 Aug 11 13:35 base-feed.conf
-rw-r--r-- 1 root root 92 Aug 11 13:34 mvblx-feed.conf
-rw-r--r-- 1 root root 77 Aug 11 13:35 noarch-feed.conf
-rw-r--r-- 1 root root 1090 Aug 11 13:30 opkg.conf
arch.conf
contains details about the different ARM packages and should not be changed.
•
opkg.conf
contains the configuration of the update program opkg and it is not necessary to change
the file.
•
All other files like
base-feed.conf
(URL to the general armv7a packages)
•
mvblx-feed.conf
(URL to the mvBlueLYNX-X specific packages like bootloader, kernel,
MATRIX VISION software)
•
noarch-feed.conf
(URL for other packages, which are not ARM specific)
•
...
•
have to be changed to the new feed.
Example
:
matrix@mvblx:/etc/opkg# cat base-feed.conf
src/gz base http://beta.matrix-vision.com/mvblx-feed/stable/ipk/glibc/armv7a/base
13.1.2 Using a Proxy
If your camera can only reach the Internet through a proxy then you will need to set up the proxy details on
the camera before being able to update directly from the MATRIX VISION stable feed. The following step is
not
necessary if you have a transparent proxy or none at all.
Edit the file
/etc/opkg/opkg.conf
using your favourite editor e.g. vi or the installed graphical
editor gedit.
