4.1 Setup
4.1.1 Driver Installation
Download and install this driver:
http://www.ti.com/lit/zip/sbac253
. This is a one-time step per computer. Unzip
the folder and run the .exe file with administrator privileges.
4.1.2 Firmware
The firmware comes pre-installed on the SCB. Firmware updates will be pushed through the GUI (requires
previous driver to be installed). Downloaded offline GUIs may check for GUI or Firmware updates depending on
the version.
4.1.2.1 Firmware Debug
If the firmware gets corrupted or must be manually reinstalled for any reason, follow these steps to reinstall the
firmware.
1. Configure the MCU on the SCB to be in Device Firmware Update (DFU) Mode.
a. It is possible that the MCU has already entered DFU mode. If so, the GUI will notify you and try to
update the firmware to the latest version after the GUI is connected to the PC.
b. DFU mode can be entered manually through one of the following methods while the SCB is powered on:
• Through software:
– Send the command 'bsl' on the SCB's USB Serial (COM) port.
• Though hardware (with the EVM removed):
– Short the two test points labeled "DFU" (shown in
) with a pair of tweezers (or wire)
while pressing the RESET button.

2. With the MCU in DFU mode, the firmware can now be uploaded through the method outlined in Step 1.
4.1.3 GUI Setup and Usage
Access the GUI in either the Google Chrome
®
