NUCLEO-C051C8 : ST-link is not detected on windows Desktop

[rudreshjoshi]

Hi ,

Recently I got a NUCLEO-C051C8 board and tried to connect it to windows and program it using STm32CubeIDE but it does not show that st-link is connected , ST-link on board blinks RED continuously. 

Cant install it ( installation goes through , but cant see it in device manager ) using stsw-link009

( https://www.st.com/en/development-tools/stsw-link009.html?dl=redirect ) 

Cant connect using STM32CubeProgrammer. 

Tried 2 USb cables , various ports of pc but  in vain. 

Can someone please help ?

Blinking red LED means it's not enumerating. Usually due to using a power-only USB cable. Try a different USB cable or a different USB port.

Even if drivers aren't installed, something should show up in device manager as an unknown device.

Hello @rudreshjoshi and welcome to the community;

Could you please take a look at this article How to solve connection errors when connecting and programming the STM32 target board may help you to solve the issue.

Thank you

As @TDK said, try a different cable - make sure it's one that actually gives a data connection with other devices.

More things to try here.

Thanks , I am able to make it work now. 
Seems like I had to remove Jumpers from CN-2 and it did usb enumaration ( Red LED went steady ). 

Thanks a lot for your help. 

thanks & warm regards,
