TI中文支持网mmwave_studio_user_guide里面的一个操作：
SPI Connection & RF Power Up 6.1.4
The mmWave radar device communicates with the external host processor using the SPI interface. The mmWave device is configured and controlled from the external host processor by sending commands to mmWave device over SPI.1. Once the MSS firmware boot up is complete, Click SPI Connect.2. The SPI Connect button becomes SPI Disconnect indicating a success. If SPI connect does not succeed you may need to erase the serial flash and try again using the Uniflash tool.
第二步具体要怎样操作呢，烧写哪些文件呢？
3. Once SPI Connection is successful, Click RF PowerUp button. This command initiates BIST SS power up. Now, the user can issue commands to the device over SPI Communication interface. Go to section 7 to issue commands to the Radar device for RF evaluation.

我是按这个你说的这个步骤设置的，load完成bin以后，再去连spi就没反应了，我看之前的帖子有人说要把spi开关打开，但是我在iwr6843板子上没看到有这个开关。文档上的板子都是iwr1643的板子，帮忙确认下这个开关的位置，非常感谢您的回复
