Unrecognized Black Pill (STM32F401CCU6) in DFU mode #13

Closed kj-jondell closed 4 years ago

kj-jondell commented 4 years ago

Hello!

I have a problem with the Black Pill not being recognized by my Ubuntu computer (and Macbook) when trying to enter DFU mode. When I follow the instructions given for entering DFU mode (both method 1 and method 2 listed here in the repo) the board is only recognized approximately every 1 in 20 attempt. I don't really understand the "heating the chip up" instruction, but it is 25°C.

The board is recognized as an UART interface normally. I have connected it with a USB-C cable and my Ubuntu computer is a Nuc8i5.

best regards, Karl Johannes

Hello, due to STM32F401CCU6's own chip, it is difficult to enter DFU. You may need a hot air gun to heat it before it can enter the DFU. So we've upgraded the STM32F401CCU6 to STM32F401CEU6, it goes into DFU without any problems, and has more memory.

Thanks for the quick reply and clarification! I bought an ST-Link now, which works well with the STM32F401CCU6.
