3.2.3.1 Firmware Debug

If the firmware must be manually reinstalled for any reason, follow these steps to reinstall the firmware. After the firmware update (if the EVM is not already connected), power down the SCB, connect the EVM to the SCB, and then power them up together.

  1. See if the GUI can program the firmware already by following the steps in Section 3.2.2.1.
  2. If that is unsuccessful (or if the "Program Device" button is grayed out, and the SCB will not connect), 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 and connected to the PC:
    1. Through software:
      1. Send the command 'bsl' on the SCB's USB Serial (COM) port.
    2. Though hardware:
      1. For safety, turn off and disconnect all load sources and external voltages.
      2. While shorting the two test points labeled "DFU" (shown in Figure 3-6) with a pair of tweezers (or wire), press and release the RESET button.

With the MCU in DFU mode, the firmware can now be uploaded through the method outlined in Section 3.2.2.1.
