2.4 Firmware Updates

If there are issues with the PAMB controller such that it is unable to connect to the GUI or the LEDs do not light, the firmware may need to be re-flashed through a batch file.

Before this can be done, the PAMB controller must be put back into Device Firmware Upgrade (DFU) mode. The steps to put the controller into DFU mode are as follows:

  1. Ensure the USB cable is unplugged, then remove the LDC3114 daughter card from the PAMB.
  2. Locate the two test points near the PK1 and PK2 header pins.
  3. Reconnect the USB cable to power the USB board.
  4. Use a pair of metal tweezers or wire to short and hold the connection between the PK1 and PK2 test points.
  5. With the test points still shorted, press and release the RESET button (SW1) on the PAMB board.
  6. If successful, none of the LEDS on the PAMB board will be on.
  7. Launch the LDC3114EVM GUI.
  8. Navigate to File > Program Device to launch the firmware update. Wait for the firmware to update and do not disconnect the USB cable or press the RESET button during the update.
  9. When the update is complete, the EVM firmware should reboot and connect to the GUI. If the firmware does not reconnect momentarily, press the RESET button OR unplug and plug in the USB cable to reconnect.
