我将使用IDE在Sparkfun edge board中提供的一些示例，以SparkFun Serial Basic Breakout - CH340G和oficial tutorial闪烁。
尽管它已经正常运行了很多次，主要是针对示例 example1_edge_test 和 AI on a microcontroller with TensorFlow Lite and SparkFun Edge ，有时我在闪烁时会收到此消息：
Connecting with Corvette over serial port /dev/ttyUSB0...
Sending Hello.

!!!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 建立与连接的响应时，似乎会发生这种情况 AM_SECBOOT_WIRED_MSGTYPE_STATUS 。
我按住“ 14”按钮使电路板闪烁，然后按住“ 14”并按“ reset”，然后执行“ 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，错误发生的机会更多。
