# EMW3290系列模组固件烧录方法
#模块简介
- EMW3290模组是MOC108和blueNRG双芯片双天线的combo模组，两个芯片之间通过串口通讯，预留烧录引脚和wifi模块的用户串口；
- 蓝牙芯片用STlink进行调试和烧录，wifi芯片通过MOC108烧录盒子进行烧录；

安装之后运行如下：
模块的PIN 17 18 19 20引脚分别为ST-CLK ST-DIO VCC，GND引脚，与ST-link工具的对应引脚链接之后重新上电，即可在上位机软件中读取到芯片flash的内容。
此时可保存为二进制文件，方便定位问题。
另外可通过Target中的不同选项对芯片进行烧录，擦除等操作。
