安装microPython后出错，求教！

[jackmoongong]

大神们好！

我在测试ESP32-S3-box芯片
刚开始就碰到状况，我根据视频材料安装Thonny，然后安装microPython，选择的是ESP32-S3
在配置解释器，然后安装MicroPython以后。
在Thonny中显示：
Hard resetting via RTS pin...
Done!

然后电脑就不停的发出嘀嘀声

Thonny 报错，内容为：
PROBLEM IN THONNY'S BACK-END: Internal error (serial.serialutil.SerialTimeoutException: Write timeout).
See Thonny's backend.log for more info.
You may need to press "Stop/Restart" or hard-reset your MicroPython device and try again.

Process ended with exit code 0.


这是backend.log的信息：

我更换了数据线，更换了测试电脑，都显示该信息。
我不确认是ESP32-S3-box有问题，还是其它原因。

建议通过 u0 rx 和 u0 tx 连接 TTL 转usb 模块，通过串口烧录程序。https://www.google.com/search?q=TTL+%E8 ... bbAstkkf4M

当前你是通过 USB 去烧录，芯片被擦除后，Flash 内无代码 USB 重复连接导致 ‘电脑音箱嘀嘀’ 是正常现象。建议提前烧录稳定的固件。
