I do not have any experience with programming STM32 boards. In windows device manager, it says that my ST-LINK driver is up to date (latest version). The board LEDs light up and everything seems to be normal until I try to connect to the board through ST-LINK. I am getting the following error in STM32CubeProgrammer when trying to connect to the Nucleo F411RE board.
23:49:44:122 : Disconnected
23:49:48:131 : STLinkUSBDriver.dll loaded

I am using a regular cable.
In the NOD_F411RE storage F:/ I can find two files: FAIL.TXT containing
The interface firmware FAILED to reset/halt the target MCU
And DETAILS.TXT containing
Version: V2J39M27

Any ideas what I can try next? I am pretty lost.
Alright, I had my Nucleo mounted on a breadboard. Some of the pins were in shortcircuit. That's it. Disconnected it from the breadboard and it worked just fine :D. I thought that the pins would not be active without me assigning them for a certain connection.
