首先下载软件，解压软件，安装在程序中找到SEGGER,选里面的J-FLASH，进入界面，刚开始的那个界面可以忽略，不用建project也可以；单击菜单栏的“Options---Project settings”打开设置，进行jlink配置;正在General选项，选择“USB”，一般都是默认配置，确认一下即可;然后在CPU选项，选择芯片型号，先选择“Device”才能选择芯片型号，芯片型号，要根据你使用的芯片进行选择;在Target interface选项 里面选择SWD模式;首先Target里面选“Connection”连接目标芯片，然后 Target--Auto进行程序烧写;首先Target里面选择“Connection”连接目标芯片，然后 Target--Auto进行程序烧写.SEGGER J-Links are the most widely used line of debug probes available today. They've proven their value for more than 10 years in embedded development. This popularity stems from the unparalleled performance, extensive feature set, large number of supported CPUs, and compatibility with all popular development environments.
