USB driver for STM32

[SupArdu]

Uploading code to a Black pill STM32F401 does not work.
I bought the board from az-delivery and configured it like described in their documentation:

I started with the blink sketch (Arduino IDE 2.3.3).
After connecting the board to my PC (Win10, 64bit) the Tools menue offers COM15 which I selected.
I followed the proposed procedure for uploading:

Use the onboard BOOT0 and NRST button to put the board into bootloader > mode:
● press and hold the BOOT0 button
● press and release NRST (reset) button to power cycle the processor
● release BOOT0 button

But uploading ends with the message

Error: Target device not found.
Establishing connection with the device failed.

Does the STM32 need a special USB driver, or what is wrong with my upload procedure?

Buy a $2 St-Link programmer, it makes the uploading much easy.

I guess programming with ST-Link works without bootloader and then there is no Serial Monitor available for debugging?
Can ST-Link also be used for debugging?

Serial monitor has nothing to do with bootloader, you still able to use Serial if you upload the code via St- link

Hi @SupArdu.

@SupArdu

Can ST-Link also be used for debugging?

I have successfully used one of these ST-LINK/V2 as a debug probe with the GIGA R1 WiFi and Nano 33 BLE boards. I haven't tried it with any other STM32 boards, but I think there is a good chance it will work because I know the "STM32 MCU based boards" platform (AKA "STM32duino") does have support for use with the Arduino IDE 2.x integrated sketch debugger.
