Here's what I've done so far:
1. Downloaded file STM32F411DISC-20200902-v1.13(2).dfu from MicroPython.org
2. Downloaded DfuSe utility en.stsw-stm32080 and ran program DfuSe_Demo_v3.0.6_Setup
3. Powered up board by connecting mini connector to a USB port on my Win10 PC
4. 4 LEDs are blinking in a rotating mode followed by all flashing, then repeating
5. Device Manager shows STM STLink under Universal Serial Bus Devices
6. Next powered down and installed jumper on Boot0 pin to Vdd pin
7. Powered up again, Device Manager still shows STM STLink
8. Connected micro connector to another USB port. Red LED glows next to micro connector
9. DfuSe_Demo_v3.0.6_Setup is running but nothing shows in Available DFU Devices box
10. I select Choose and open file STM32F411DISC-20200902-v1.13(2).dfu
11. Still nothing in Available DFU Devices box
12. Hit Upgrade and a message appears in bottom line "Please select one or several targets before!"
13. There is nothing in the Select Targets box
Apparently, the utility does not detect the Discovery board. Also, Win10 File Explorer does not see any drive but the C drive.
Can anyone point out what is wrong?
