Hi GAcqu,

This error means CubeIDE was able to find your ST-Link device, but no target chip connected to it. Are you using a Nucleo? If so, are the jumpers on the board connected properly?

Kind regards,

Hello @GAcqu.1​ and welcome to the Community :)

Can you connect with STM32CubeProgrammer?

Make sure to update the ST-link firmware.

Check the USB cable, jumpers. You can try a different cable and/or USB port, boards.
