STM32 Nucleo F411RE ST-LINK error (DEV_TARGET_CMD_ERR)

Question

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
  23:49:48:133 : STLinkUSBDriver.dll loaded
  23:49:48:133 : ST-LINK SN  : 066CFF545150898367065053
  23:49:48:133 : ST-LINK FW  : V2J39M27
  23:49:48:134 : Board       : NUCLEO-F411RE
  23:49:48:134 : Voltage     : 4.89V
  23:49:48:137 : Error: ST-LINK error (DEV_TARGET_CMD_ERR)
  23:49:48:147 : Disconnected

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
Build:   Oct 22 2021 16:50:45

Any ideas what I can try next? I am pretty lost.

you can simply drag and drop your .bin file over, you dont need to use stlink. — old_timer, Feb 27 '22 at 22:37
I normally update the firmware on the board when I get a new one. its a java tool , works on whatever operating system. — old_timer, Feb 27 '22 at 22:38

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.

The Nucleo F411RE is already equipped with a JTAG interface. If you want to use your stlink, you probably have to disconnect the upper part of the board (which is the JTAG interface).

that debug interface supports stlink, and I suspect that is what they are trying to use. – old_timer Feb 27 '22 at 22:36
You are probably right @old_timer, but I was confused by the statement "I try to connect to the board through ST-LINK". – niavlys Feb 28 '22 at 08:23
I assume folks think they need to but for a number of these boards you just drag and drop and maybe use stlink for debugger stuff, can use it for loading as well, but ... – old_timer Feb 28 '22 at 21:32
@Sergiu Fratila has to clarify its question. – niavlys Feb 28 '22 at 21:35
yes a clarification is required. more information needed on the problem. – old_timer Mar 01 '22 at 14:55
