I have constantly been getting this error while trying to upload a sketch on Wemos D1 Mini R1 & R2 type board.
A fatal esptool.py error occurred: Write timeout
I've recently updated my Arduino IDE, so I assumed that it might be due to a bad installation. But after reinstalling everything including the Board Manager lib for ESP, Arduino IDE itself nothing worked. When I click on the Board Info, it displays an error "Native serial port, can't obtain info".
I've also tried different type of ESP boards (e.g. NodeMCU) but for all boards the problem is same. When I plug an Arduino to the same USB Port, it auto-detect the board, but when I plug-in the ESP boards, it doesn't recognize the boards automatically. So my guess is it has something to do with the CH34X driver. However I have tried reinstalling few versions of the driver from authentic sources, but nothing made an impact.
Any help is appreciated.
