Hi,
GCC is installed along with the RKit-ARM kit.
This means that when you update the RKit-ARM kit, you have to update GCC too if the new RKit-ARM includes an update of GCC.
If you are upgrading the Ride7 kit, then you must uninstall everything, then reinstall the new Ride7 kit, and then reinstall the RKit-ARM kit that you had before, which will reinstall the same GCC.
Best Regards,
Vincent
