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
