Firmware Flashing Instructions

How to Determine Which Firmware You Need

warning

Note: Since the C8P is an integrated mainboard for both upper and lower computers, you must choose the USB firmware unless you are using a CAN tool board!!!
When using a CAN tool board, you must choose the CAN bridge firmware.
RS232 does not require flashing any firmware on the mainboard, but the corresponding tool board needs to have the RS232 firmware flashed.

USB Firmware
- Advantages: The most commonly used connection method in 3D printers, reliable and stable communication.
- Disadvantages: May affect data transmission if multiple USB devices are connected.
USB Bridge Firmware
- Advantages: Can connect multiple devices simultaneously without occupying USB ports. Only required when using a CAN tool board.
- Disadvantages: The initial firmware compilation and flashing process can be more complicated.

The FLY C8P uses DIP switches to select the connection method between the upper and lower computers. If the DIP switch positions are incorrect, the upper computer may fail to connect to the lower computer. Please pay close attention!!!

Important Notes

For normal use, set the DIP switch to the upward position.
When adjusting the DIP switch, push it all the way up; otherwise, the lower computer may not connect!!!
