When I upload my sketch (I have to press reset button) it uploads fine, and switches to COM25. I flashed the latest bootloader into my new BPill (it flashes 6x fast and 6x slower upon reset). I googled combinations of "STM32 Blue pill USB driver unknown device" and followed the links, but none of them solved the issue.Īny idea what the problem is or how I can diagnose it any further ?
I must be doing something wrong or missing a step but I cannot find what. stm32loader.py -p COM4 -w generic_boot20_pc13.binĤ) as it didn't solve the issue, also followed the bootloader burning instructions on the Wiki although they talk are about the black pill, so I substituted the binary file with the one from above.Įach time, I made sure burning was made with the top jumper on "1" and running with the top jumper on "0" (the bottom jumper stayed on "0" all the time), and reseting the board after each jumper change.Īs I thought maybe there was an issue with the OS, I performed the driver installation on a second OS, to no avail. It popped up 3 command windows: one (calling the two others) saying:Ĭode: Select all D:\temp>python. When connected, Windows pops up (the French version of) this message, and in the device manager, an "Unknown device" shows up under USB bus controllers (French version of this)ġ) replaced the 10K SMD resistor R10 by a 1K5 one, as indicated on the wiki.Ģ) installed the driver by starting "Arduino_STM32\drivers\win\install_drivers.bat".
Using micro USB to communicate with the board.

Flashed the SerialCallResponse sample sketch using serial => success, works as expcted Flashed the Blink sample sketch using serial => success, works as expcted Connected the blue pill using a USB-serial adapter Added and configured Arduino_STM32 to my Arduino IDE I'm pretty sure I'm missing an important step but I really can't figure out which one, so after a full day of research, I decided to post here, even if I look like a newbie - which I am regarding STM32 btw.
