无法正常将程序下载到开发板

如果在下载过程中出现错误提示
有时候是
A serial exception error occurred: device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Note: This error originates from pySerial. It is likely not a problem with esptool, but with the hardware connection or drivers.
