FY Autopilot & AFSS Firmware

Upgrade Procedure

WARNING – Before firmware upgrading:

A) Remove the FY module (FY-30A\FY-31AP\Hornet\Panda…) from all connections (Remove

ESC/RC wires).

B) Do not disrupt the Firmware uploading process (e.g. moving your laptop resulting is lost

connection). Disrupting the process can damage your FY30A processor.

C) If you are using a portable computer, make sure you have enough power to carry through the

updating process. This is to prevent B) above.

D) Follow the steps below EXACTLY CHRONOLOGICALLY.

If you skip any step, firmware upgrade will fail.

Very importamt: we strongly recommend when doing the upgrade process please use the USB

cable power supply to the FY module. Because if you use the External power source supply, you have

to very strict control the power on time for the FY module.（You can not power on the FY module over

the normal operating voltage） Cannot power on until you have “open port” and also the USB cable

have been connect with the FY module, or it may cause the firmware upgrade fail.

Attention:

1) Connect the USB data cable to your PC(Do not connect the FY module to the USB data cable)

2) Open the firmware upgrade software, choose the right COM port, baud rate 19200, the FY module

type(Like FY-30A,FY-31AP…), and click on “ Open ”

3) Connect the FY module to the USB data cable after open port.(Usually through the FY module

UART port, but you should through Hornet-OSD “GND +3.3V TX RX” port do the firmware

upgrade for Hornet-OSD, and FY-41AP UART2 port do the firmware upgrade for FY-41AP OSD

part.)

4) When you do the firmware upgrade for FY-41AP OSD part, please notice that: You should

choose the “FY-41-OSD” from the products type pull-down menu.

Following operate is default for use the USB cable for the power supply.
