Upgrading Falcon OSD Firmware

To upload the latest firmware to your Falcon board, please follow these upload instructions:

    1. Download the appropriate Falcon .zip file by clicking on the Falcon OSD V1.0.2 button on this webpage.
    2. Copy the attached zip file to your desired location, right click on it and extract it into a directory. The directory contains three files: a binary (.hex) file that contains the new firmware, an executable called “avrdude.exe” and a configuration file called “avrdude.conf”, that are used to upload the hex file on to the OSD board.
    3. Connect the FDTI boards serial port to the Minim/Micro Minim OSD board.

Micro Minim OSD

    1. Connect FTDI board’s USB to the PC, this will power up both the FTDI and OSD boards.
    2. You should hear a device connection tone on the PC. If the FTDI board hasn’t been connected before, it may need some time to search for the required drivers.
    3. To find FTDI board’s COM port in Windows go to the start button in the bottom left hand corner and select “Device Manager” from the pop-up menu, then select “Ports (COM & LPT)”. On Linux machines use the “lsusb” command.

Device Manager 2

    1. Start the command prompt or console window.
    2. Type the following into the command prompt:

    avrdude -c arduino -p atmega328p -P COM6 -b 57600 -U flash:w:FalconOSD_V1.0.2.ino.hex

    The FTDI board should upload the program to the OSD board and verify the transfer.

    Command Prompt OSD

    1. After the upload remove the USB cable from the PC and disconnect the OSD board.
    2. Connect the Minim/Micro Minim OSD board via an I2C Level Shifter to the Falcon flight controller on Serial1, this is detailed on the Falcon Interfaces webpage.
