Welcome @VietNam_2026, to the community!

Your screenshot shows a very old firmware version V2J29S7 for your ST-LINK/V2, which suggests that you are using a clone. Please check this again. You are welcome to insert a photo of the front and back of the ST-LINK using the camera button.

Regards

That looks like an original ST-LINK/V2. Please start the firmware upgrade with the current STM32CubeProgrammer (light blue button in the middle right). After that, you should have the firmware version V2J46M33 or V2J47M34; otherwise, there is something wrong with your ST-LINK.
