3.1.2.1 Firmware Debug

If the firmware must be manually reinstalled for any reason, then 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.
    1. Plug in the SCB controller to the PC
    2. Launch the GUI
    3. A possibility is the MCU has already entered Device Firmware Update (DFU) mode. If so, then the GUI can notify and try to update the firmware to the latest version.
    4. If the GUI does not update automatically, then go to File > Program Device....
  2. If step 1 is unsuccessful (or if the Program Device button is grayed out), then 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:
    1. Through software:
      • Send the command bsl on the USB Serial (COM) port of the SCB.
    2. Through 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.

      • If using the PAMB board instead, then these test points are placed near PK1 and PK2.

With the MCU in DFU mode, the firmware can now be uploaded through the method outlined in Step 1.
