Hi Alice,
The problen is solved. I've ran below script and it can be flash with Segger setting.
Hello @Eason_L
Thanks for your question.
Was it working properly before? If yes, How about entering ISP mode, then erase full flash.
If still can't work, please take a video or screenshots show your detail steps.
