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 before being powered on.

  1. First, see if the GUI can program the firmware.
    1. Plug in the SCB controller to the PC.

      1. Make sure the EVM is connected to the SCB first.

    2. Launch the GUI and close the README.md window.

    3. If the MCU is already in Device Firmware Update (DFU) mode, then a popup window appears saying "Connection Failure - No SCB controller detected".

      1. Close this window.

    4. If the GUI does not update automatically, then go to File > Program Device...
      1. If the Program Device... button is still grayed out, then click the connect button in the lower left corner and then try again.
  2. If step 1 is unsuccessful (or if the Program Device... button is still 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 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 3-1) with a pair of tweezers (or wire), press and release the RESET button.

      • If the PAMB board is being used instead, then these test points are located near PK1 and PK2.

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