Issue with code uploading in STM32 Blackpill

anindya003 · ‎2025-03-17

Hello everyone,

Who so ever is seeing the post please help me out

I was trying to upload code into STM32 blackpill (STM32F401CCU6) using USB cable and STMCubeIDE and STMCubeProgrammer but I think my STM board had got locked in the DFU state and even after power cutting also the blue led is not flashing nor after hitting the reset button anything is working more over the STM32CubeProgrammer is unable to recognise the board and showing No DFU found.

But my device manager is showing the STM32 Bootloader

Please help me out

What happens if you press the Boot button, then, holding it pressed, press and release the Reset button?

Note that Black (and other colour) Pill is not an ST board, and is likely to have a fake STM32 ...

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
