Unable to debug the code into device DA14681-01

你好！

I am using device DA14681-01 for my research work. we have purchased DA14681 for creating a prototype. However, I am facing a problem while loading the code into the chip. Initially, I started with the basic code to blink the D2 led. but I am getting the following error. I have tried to find this error on your forum but could not get any answers.

请帮帮我，提前感谢。按照下面进行错误。
