Seems like I cannot flash the ESPBasic on my Wemos D1 Mini.
When I try I get the following:
Warning: espcomm_sync failed
error: espcomm_open failed
Any suggestions?
Thanks,
Tony

Hi, have you loaded the driver for the CH340 on board USB to serial converter? If not google CH340 driver.

Is it possible you have a serial terminal open already? Only one program can use a serial com port at a time.

The driver was installed when I plugged in the device, and verified in Device Manager.
Also, I can access it via another program, LuaLoader and it works fine.
As far as I know, no other program is accessing that com port when I run the Basic Flasher.
