Nucleo-F446RE ST-Link - Device not detected after attempting to update firmware

[MedSid]

I am facing an issue with my Nucleo-F446RE board. It was working normally before, but now when I connect it via USB, the ST-Link LED lights up red, and I cannot upload code, nor does STM32CubeIDE recognize it. I tried updating the ST-Link firmware using the ST-LinkUpgrade tool (STSW-LINK007), but the program displays an error message: "No ST-Link device detected. Please connect it and then retry," even though the computer recognizes the ST-Link in Device Manager as "STMicroelectronics STLink Virtual COM Port (COM6)."

I have verified that the CN2 jumper settings are enabled (ON).
I cannot install the drivers or update the firmware because neither ST-LinkUpgrade nor STM32CubeProgrammer recognizes the board.
I kindly request your help to identify the reason why ST-Link is not being detected and how to resolve this issue.
Thank you in advance for your assistance.

Hi,

to check, st-link has correct firmware, try:

download STM32 CubeProgrammer , update your st-link (and set the used frequency for MCO as you want it to be.);

then try connect and see: connecting ....or not.
