你們的手冊上寫著按住 SW1 鍵直到閃紅、藍、紫燈就可以進入MSD mode，不過我按了很久都沒辦法進MSD mode，是不是產品的缺陷?
Your manual says that just hold SW1 key to enter MSD mode, But I still couldn't enter MSD mode. I want to know if it's your product's problem?
Are you holding SW1 during boot? As you mentioned it should enter MSD mode by doing this. Could you please explain what is the behavior you are seeing on your side?
It's OK now, thanks
