If you are using Help > Check for Updates option to check for new service packs or patches, you may get the message "There is nothing to update", even when patches and service packs are available.
This happens because the Check for Updates option, checks for updates available for already installed packages or features. The Check for Updates option scans through the list of the installed plugins and contacts the configured and enabled update sites (for your reference, see the image listed below).
For example, if you have installed a service pack, the CodeWarrior software will search for an update available for the service pack. However, it will not search for the recent Kinetis compiler, as the Kinetis compiler has not been installed previously as a separate package or feature.
To install new service packs or patches, use the Help > Install New Software option. While installing new software, make sure that you clear the Contact all update sites during install to find required software checkbox.
Also, note that if the CodeWarrior software needs to access updates through proxy, you need to configure the network connections.
