Error while uploading to STM32 Nucleo64 F411RE - OpenOCD init failed

Hey All,

I’m trying to upload sample code to my STM32 Nucleo64 F411RE board, but I haven’t been successful.

The error I get when trying to upload is

This indicates to me that the issue is when connecting to my STM32 board. Now, the board’s LEDs are on (so that means it’s not power-related). I also have it connected on virtual com port 3.

I have tried following the documentation on ST Nucleo F411RE — PlatformIO v6.1 documentation and also checked a user with a similar error at ** OpenOCD init failed ** - Nucleo-F401RE, but it was to no avail.

Can someone help me if they get a chance?

my platform.ini file is the following:

platform         = ststm32
board            = nucleo_f411re
framework        = arduino
upload_protocol  = stlink
upload_port      = COM[3]

Thanks for the help!
