Hello @luna_liang ,

Thanks for your post.

To update the MCU-Link’s firmware it must be powered up in (USB) ISP mode. To do
this insert jumper J4 then connect MCU-Link to your host computer using a micro B USB
cable connected to J1. The red STATUS LED (LED3) should light and stay on. Then the board will
enumerate on the host computer as a HID class device. 

Please have a try as below. If your issue has not been resolved, please feel free to contact me again.
