Info
titleopfw / bin files

Please note all the files above are bu_[BOARD].opfw, if you plan to flash a .bin file the DFU method or ST-Link method should be used.

Unfortunately, the CPU used on the CC3D flight controller does not support the DFU bootloader, see this page for flashing bootloader using a FTDI connected to the main port.

This need a working firmware into the board, connecting to the GCS. This is the preferred method when all is fine.

After the board is connected to the GCS, go to the firmware page and click the 'Upgrade' or 'Upgrade&Erase' button.
The board will:

  • reboot automatically,
  • flashed using the appropriate firmware for the board,
  • reboot and erase settings if needed,
  • and finally remains connected, running the new firmware that matches your GCS.

This is the preferred method after you flashed a bootloader, the board do not boot (because no firmware running) and there is a slow fading led blinking.

The manual method is similar to the previous automatic method but do not use the automatic reboot at start:

Steps for manual update:

  • Disconnect board from the USB port and disconnect external power (Lipo) if any.,
  • Click the 'Upgrade' or 'Upgrade&Erase' button. (Board still disconnected)
  • Connect board to the USB port

The board will:

  • be recognized just after connected to the USB port,
  • flashed using the appropriate firmware for the board,
  • reboot and erase settings if needed,
  • and finally remains connected, running the new firmware that matches your GCS.
