I'm working on a project for uni and I would like to use PlatformIO for the project development, since it seems more practical than the Arduino IDE. However, I keep getting this error when trying to upload any file to my Nucleo F303RE.

*** [upload] Error 1

This is the whole upload log when I try to upload the project (after already compiling it).

I've read through some other topics and the errors others seem to have with other boards was that they're improperly connected/missing a channel/etc. but the Nucleo should only need the one usb cable.

The Nucleo works fine with the Arduino IDE and I was able to upload to it many times, so I don't understand why it gives a LIBUSB_ERROR_NOT_FOUND. I also tried setting the exact upload_port to com7, which is the usb port I use, but it didn't change anything.

Does anyone have any insights? Cause I'm not experienced enough to fix this...

ETA: My platformio.ini is this:

[env:nucleo_f303re]
platform = ststm32
board = nucleo_f303re
framework = arduino
