4.2.1 Setup
4.2.1.1 Driver Installation
Download and install this driver: https://www.ti.com/lit/zip/sbac253 . This is a one-time step per computer, and will
require a myTI account. Note that this driver is labeled as a PAMB driver, but is also used for the SCB. Unzip the
folder and
run the .exe file with administrator privileges .
4.2.1.2 Firmware
The firmware comes preinstalled on the SCB Controller. Firmware updates will be pushed through the GUI
(requires previous driver to be installed). Downloaded offline GUIs will only update the SCB Controller with the
latest firmware available at the time of download. To check for the latest GUI or Firmware updates, launch the
latest GUI version from the web browser.
4.2.1.2.1 Firmware Debug
If the firmware gets corrupted or must be manually reinstalled for any reason, follow these steps to reinstall the
firmware. Make sure the EVM is connected to the SCB.
1. First, see if the GUI can program the firmware manually.
a. Plug in the SCB controller to the PC
b. Launch the GUI
c. It is possible that the MCU has already entered Device Firmware Update (DFU) mode. If so, the GUI
may notify you and try to update the firmware to the latest version.
d. If it does not update automatically, go to File > Program Device...
2. If step 1 is unsuccessful (or if the "Program Device" button is grayed out), manually configure the MCU on
the SCB Controller to be in DFU Mode. This can be done through either of the below methods with the SCB
Controller powered on:
a. Through software:
• Send the command 'bsl' on the SCB's USB Serial (COM) port.
b. Though hardware:
• For safety, turn off and disconnect all load sources and external voltages .
• While shorting the two test points labeled "DFU" (shown in Figure 4-3 ) with a pair of tweezers (or
wire), press and release the RESET button.
Figure 4-3. Test Points Used to Enter DFU Mode Manually
• If the PAMB board is being used instead, these test points are located near PK1 and PK2.
With the MCU in DFU mode, the firmware can now be uploaded through the method outlined in Step 1 .
