Device 2D42 does not turn on, it is impossible to transfer to the programming mode. Previously there was an interrupted procedure for updating the firmware.

Connect the scope to your computer, open Dfuse Demo. In Device frame, will "STM Device in Dfu Mode" be displayed?

If there is, please update again and keep the USB cable line not moving at the same time.

Hello, during the firmware update 2D42 I had the same problem (the process was interrupted and the device is no longer turned on). F1 / Power combination does not work. Can you please tell me how to restore the device?

I got all the connection right, but it cannot connect to device to flash it.

Sir, sorry, I don't know how to help you.You can check this question online.

Did you connect RX and TX in reverse?

What's wrong with the USB to TTL module?
