Couldn't find the DFU device: [1EAF:0003]

Post by FiveO » Mon Oct 16, 2017 7:12 am


I'm new to STM32. I have troubles uploading blink sketch to STM32F407VET6 STM32_F4VE V2.0 1509. I am using Windows 10, Arduino IDE 1.8.4. My board BOOT0 is in 3.3v, when the board arrived the boot pins were BOOT0-GND, BOOT1-GND and D2 and D3 blinked together. R19 and R18 resistors seems to be 220. Arduino IDE shows "Couldn't find the DFU device: [1EAF:0003]" and Windows 10 Device Manager is showing STM Device in DFU Mode.

What I am doing wrong?
