[Nucleo- F411RE] Setting Up To Work With Putty

Post by mat_wey » Mon Jul 19, 2021 7:18 pm

*Full initial disclosure - I am quite new to the coding community and this is my first time setting up an MCU, so please bear with me*

I am attempting to set up an STM32F411RE with micropython and to be able to use the board with PuTTY for an easier coding experience in the future. I have successfully downloaded the micropython .dfu file for the F411re board from the micropython website and uploaded to the board using DFU. At this point however I am not quite sure how to proceed to get putty to successfully communicate with the board. I have the com port in the putty terminal matching with the corresponding com port on the device manager, but no response when I open up the Putty terminal.

Any help would be greatly appreciated!

Putty must be set to 115200 Baud, 8 Data bit, 1 stop bit, no parity, no flow control (!).

I applied all of those parameters, but there still appears to be no communication occurring between the putty and nucleo :/

Can you confirm the steps you used to flash the DFU file? Just to ensure that this part definitely succeeded.

The 411 nucleo is a bit annoying because it doesn't have a USB interface available to the main MCU so the regular DFU flashing methods aren't available. You must program it via the ST-Link USB interface.
