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.

The first time a SCB is used with this EVM, it may need to be flashed with the proper firmware by going to File → Program Device in the GUI. In some cases, the SCB will be recognized by the GUI and can update to the proper firmware. If this is not the case, the SCB will need to be put into DFU mode by using the following steps:

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. DFU mode can be entered manually through one of the following methods while the SCB is powered on:
   1. Through software:
      • Send the command "bsl" on the SCB's USB Serial (COM) port.
   2. Though hardware (with the EVM removed):
      • Short the two test points labeled DFU (see Figure 2-6) with a pair of tweezers (or wire) while pressing the RESET button. If this is done correctly, LED D1 on the SCB should turn OFF while LED D5 (the power LED) is still ON. If LED D1 is still ON, the GUI firmware is still active and the device has not entered DFU mode.

2. With the MCU in DFU mode, the GUI should recognize the SCB. After GUI recognition, go to File → Program Device to program the SCB.
