My ST-Link isn't connecting. I tried a lot of configs and nothing fix it.

My board has the C031C6 nucleo, my attempts were:

• Change the USB for a data cable;
• Try to connect with the under reset and software reset on the Programmer;
• Update the firmware and driver on the Programmer, IDE and ST-LinkUpgrade;
• All of this with and without the jumpers (CN2 and JP1) and the problem remained.

Errors that appeared on the Programmer during the attempts:

• No debug probe detected;
• No STM32 target found;
• Unable to get core ID;
• No ST-Link device found.

What should I do?

(P.S.: English isn´t my first language, so I`m sorry for the mistakes.)

If the ST-Link isn't detected, you're probably using a power-only USB cable or one that is bad. The LED should turn solid RED once a connection is established. What is the LED (LD1) doing?

Show a screenshot from within STM32CubeProgrammer when everything is connected.

The LED is solid RED now. Here is the screenshoot of the Programmer:

I found the error. The jumper JP6 isn't connect. Thanks TDK for the help.
