Install Stellaris ICDI Drivers
Installing Driver for Tiva C Series LaunchPad board
Each Tiva LaunchPad board has onboard debug interface, called In-Circuit Debug Interface (ICDI), which allows programming and debugging of the microcontroller. In order to debug and download the code in the microcontroller's Flash memory, you must install the appropriate drivers on the host computer.
You can download "SW-ICDI-DRIVERS: Stellaris ICDI Drivers - Current" from TI website. It includes following drivers:
- Stellaris Virtual Serial Port
- Stellaris ICDI JTAG/SWD Interface
- Stellaris ICDI DFU Device
These drivers provide the debugger with access to the JTAG interface and the host PC with access to the Virtual COM Port. To use the ICDI, follow the instructions in the Quick Start document (SPMU287) to install the drivers on your host computer.
Update Drivers
When the TI Tiva LaunchPad boards are connected to the computer for the first time, the computer detects the onboard ICDI interface and the Tiva C Series microcontroller. Drivers that are not yet installed display a yellow exclamation mark in the Device Manager window.
- Open the Device Manager window. Under the category Other devices, you should see two (or three) In-Circuit Debug Interface devices with yellow exclamation marks.

- Right-click one of these device entries and select Update driver.

- A windows prompt asks: How do you want to search for driver software? Select Browse my computer for driver software.

- Under Search for driver software in this location, click Browse. Browse to the known location on your computer of the driver installation files. Click OK. Check the Include subfolders option, and then click Next.

- Windows now displays a status window that shows where it is currently searching the drivers. No user action is required at this point.

- The system then displays an Installing driver software... status window; this message indicates that the drivers were found in the specified location, and that they are being installed:

- A warning may appear that says Windows can't verify the publisher of this driver software. This message appears because the driver is not signed. Click Install this driver software anyway to proceed.

- When the installation is complete, Windows displays a message that says Windows has successfully updated your driver software. On the same message window, one of these three devices should be listed:
- Stellaris Virtual Serial Port
- Stellaris ICDI DFU Device
- Stellaris ICDI JTAG/SWD Interface
For example, the next Figure shows when the driver for the Stellaris Virtual Serial Port has been successfully installed. Click Close to close the dialog box.

- Repeat the same process to install the drivers for the remaining one (or two) devices.
