Are there additional software packages available for the ipCore basic firmware?

Yes, the ipCore firmware is OpenEmbedded based. Thus there are package feeds that can be used.

We suggest using the Yocto feeds for version 1.7.3.

To add the feeds to your system do the following:

1.) Create a new config file in /etc/opkg
vi /etc/opkg/feeds.conf

2.) Add these two lines
src all
src armv5te

3.) Update the database
opkg update

4.) Get a list of available packages
opkg list

5.) Install the desired packet
opkg install packet_name
