I see. Let me see if I’m getting this. I’d use the following command to add the repo of the i586 files into the list of packages of the opkg:
echo "src i586 http://iotdk.intel.com/repos/1.1/iotdk/i586" > /etc/opkg/base-feeds.conf
So when you are using the command opkg update you are not getting updates, right? What message are you getting? The packages available should be listed in /var/lib/oppkg/i586 can you see the ones you need?
