Hi David,
[quote user="David Bell"] I thought the whole reason for the SW-TM4C-2.0.1.11577.exe was to add Tiva C series support to an existing CCS installation.[/quote]
Actually, this is the installer for TivaWare - the target software package for Tiva. It includes libraries and example code for Tiva. It does not actually add Tiva support to CCS. Assuming you have CCSv5, you need to rerun the installer and select the option to "repair" your installation. From there you can add additional components. If you took an IDE update, you may not be able to do this "repair" and need to reinstall CCS and make sure you install the Tiva components.
Thanks
