Sparkfun边缘消息“ ！！！！有线升级失败！！。。。。。终止脚本”

Question

我闪烁着Sparkfun边缘板与SparkFun串行基本突围- CH340G使用一些的例子是，IDE中提供了公报教程。

尽管它已经正常运行了很多次，主要是针对具有TensorFlow Lite和SparkFun Edge的微控制器上的示例example1_edge_test和AI，有时在闪烁时会收到此消息：

!!!Wired Upgrade Unsuccessful!!!....Terminating the script

当脚本AmbiqSuite-Rel2.0.0 / AmbiqSuite-Rel2.0.0 / boards / SparkFun_Edge_BSP / bsp / tools / uart_wired_update_sparkfun.py建立与板的连接时，似乎会发生这种情况，该板会以不同的消息（未知）响应该板的响应对于UART闪烁：AM_SECBOOT_WIRED_MSGTYPE_STATUS。

我按住按钮“ 14”闪烁板子，按“重置”，然后在按住“ 14”的同时执行“ make bootload”。

编辑：替代方法

我一直在对这个问题进行故障排除，它必须与通信时间有关，因为当我更改波特率（最初设置为921600）时，错误发生的机会更大。
