If the firmware becomes corrupted or requires manual reinstallation for any reason, follow these steps to restore the firmware. This is demonstrated in the TMAG5170 EVM Quick Start Video:

1. Configure the MCU on the TI-SCB Controller to Device Firmware Update (DFU) Mode.
   1. The MCU entering DFU mode is possible. If so, then the GUI sends a notification and tries to update the firmware to the latest version after the GUI is connected to the PC.
   2. DFU mode can be entered manually through one of the following methods while the TI-SCB Controller is powered on:
      • Through software:
        • Send the command 'bsl' on the TI-SCB's USB Serial (COM) port.
      • Though the hardware:
        • Make sure TI-SCB is connected to the PC through a USB
        • Short the two test points near PK1 and PK2 of the header pins (see Figure 3-7) with a pair of tweezers (or wire) while pressing the RESET button.

   3. LEDs D1 and D2 are off if successful.
2. With the MCU in DFU mode, upload the firmware through the GUI:
   • Open the File menu and select Program Device.
   • The firmware update initiates.
   • After the GUI re-initializes, the TI-SCB automatically connects.

If the firmware programming was unsuccessful, then TI recommends to repeat the above steps with a different USB port connection on the machine.
