3.1.2.1 Firmware Debug

If the firmware must be manually reinstalled for any reason, then follow the steps below to reinstall the firmware. Make sure the EVM is connected to the SCB.

  1. Check to see if the GUI can program the firmware manually.
    1. Launch the GUI.
    2. Plug in the SCB controller to the PC.
    3. Check to see if the MCU entered Device Firmware Update (DFU) mode. If so, then the GUI notifies the user and attempts to update the firmware to the latest version.
    4. If the GUI 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 through software or hardware:
    1. Through software:
      • Send the command 'bsl' on the SCB's USB Serial (COM) port.
    2. 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 4-1) with a pair of tweezers (or wire), press and release the RESET button.

With the MCU in DFU mode, upload the firmware through the method outlined in Step 1.
