CB5654开发板测评2

上一篇（https://bbs.eeworld.com.cn/thread-1187454-1-1.html）只根据原理图对板卡进行了分析，本篇直接上电看看。

平头哥的这款CB5654开发板采用Φ5.5的接口，使用5VDC供电，因此我们直接在电源中串入一个功率计，通上电，听到“正在启动”，同时可以看到功率如下：

  

大概是1w左右。

连接SecureCRT查看打印信息，串行选项如下：

  

主要是波特率115200，其它基本保持缺省即可。

按一下板上的reset，读取打印信息，主要就是板卡启动和尝试连接：

从这些打印信息来看的话，板卡大约2s就可以启动完成，接下来就是一直尝试连接一个C301-F51B的ssid，其psk密码为jiubugaosuni。

“就不告诉你”？板上自带的这个密码还真有趣。

在电脑中尝试建立这个无线接入点。

开启360的WiFi共享大师，填入上述信息

  

开启WiFi。可以看到有设备连接进来，同时听到：“网络连接成功”的语音。

  

在SecureCRT上，可以看到有连接信息：

从打印的信息来看，似乎是希望从occ.t-head.cn/api/image/ota/pull读或者写一些什么。

打开wireshark，尝试抓一下，看看到底在干啥

  

可以看到，的确是post了一个信息，但是服务器的回应不算友好，直接粗暴的告诉说：设备没有找到，没有信息回复，代码为-1……
