BL Firmware

Tip

Please note that the bootloader has been pre-flashed at the factory; no need to re-flash.

Entering Flash Mode

Tip

Left is the BOOT button, right is the RESET button.

There are two methods to enter flash mode.
Method 1: With the tool board completely powered off, hold down the BOOT button, then connect one end of the TYPE-C cable (with data transfer capability) to the motherboard and the other end to your device.
Method 2: After connecting one end of the TYPE-C cable (with data transfer capability) to the motherboard and the other end to your device, hold down the BOOT key, then press the RST key. Release the RST key, then finally release the BOOT key.

FLY-Firmware/MainBoard/E3

Notice

To ensure successful STM32 flashing, please note the following:

The USB port on some computers may cause unstable flashing due to driver or signal compatibility issues. It is recommended to try a different USB port for connection.
If changing ports does not work, an effective solution is to connect via an external USB hub, which often improves compatibility.
When the flashing software reports the error shown below, please also prioritize trying a USB hub. If the issue persists, check or use the host computer for flashing.

This step is not required for FLY host computers.
If installation is needed, ensure the host computer is connected to the internet.
If the flashing tool has already been installed, this step can be skipped.

sudo apt update
sudo apt install dfu-util -y

Execute the following command to confirm whether the device is successfully connected:

lsusb

If the DFU device is not recognized, try re-entering flashing mode.
In some system versions, the device name may differ. As long as 0483:df11 appears, it indicates successful entry into flashing mode.

Below are the precompiled firmware files. Please select the corresponding command to download based on your system type (ensure the host computer has internet access).

For standard systems:

cd && git clone https://cnb.cool/3dmellow/FLY-Firmware.git 

For FLY host computers:

git clone https://cnb.cool/3dmellow/FLY-Firmware.git /data/FLY-Firmware
ln -s /data/FLY-Firmware /root/FLY-Firmware

If the firmware package has already been downloaded, it is recommended to update it to the latest version before proceeding:
```
cd ~/FLY-Firmware && git pull
```

The previous repository is no longer maintained. If you need to delete it, execute:
```
rm -rf ~/FLY_Katapult /root/FLY_Katapult
```

Tip

Only one firmware needs to be flashed.

Below is the firmware flash command:

sudo dfu-util -a 0 -d 0483:df11 --dfuse-address 0x08000000 -D ~/FLY-Firmware/MainBoard/E3/E3_V2.bin

Flashing is successful when the following content appears: File downloaded successfully

After flashing is complete, completely power off the motherboard once.
