Hello! No DFU
Zadig and impulseRC are helpless. I've used Zadig on my FC like 3 times and it was able to restore the DFU, but now something went horribly wrong.
1) I connect the FC and the green LED is on, the red one was always blinking. Windows reports unknown device. Naturally, I installed the Windows USB drivers referenced for my laptop.
2) I started Zadig and select show all (I see unknown device).
3) install STM32 Virtual COM Port Driver https://www.st.com/en/development-tools/...32102.html
4) I check if you can see STM32 in zadig. Do not see. The treatment with virtual drivers is taken from the tutorial as a rescue route.
5) it should be like in the picture but it is not. I don't see STM32
6) I changed the USB cable, used impulseRC, reinstalled the system to windows 7, removed other devices from FC.
6a) I unplugged the FC from the USB and kept the BOOT button pressed for 10 seconds
7) my FC model as in the video second from the top http://mechatronikaedu.blogspot.com/2022...-vbat.html . The red LED used to flash, now only the green one is on. I'm out of ideas. I probably damaged the UART (USB) Bootloader or the BOOT button got stuck. Maybe there is some patent for shorting some pins instead of the BOOT button. I'm starting to think about buying.
