I am usig Flywoo GOKU F4 V2 AIO - F405 FC board for my 3inch drone. I do not have problem with the software but after arducopter software install I can not get the board in DFU mode. This board has on board SPI based ELRS receiver some discussions indicates that the this elrs receiver needs to be disabled. I tried different ways but seems like it is not possible to disable the receiver.
Before installing the arducopter software I could only get the board to DFU mode was by using ImpulseRC_Driver_Fixer.
I have even tried the method recommended by Flywoo support which is:
If you cannot enter DFU mode, please try the following methods
- Connect USB to the computer
- Press and hold the BOOT button
- Touch both ends of the capacitor with tweezers, and the configurator port will change to DFU mode
- Rewrite the firmware
noting seems to work.
İs arducopter bootloader is the problem. The board came with betaflight pree loaded and had no problem getting the board to DFU mode using ImpulseRC_Driver_Fixer.
