already try to connected D3 to ground but still got error with flash
Something went wrong. It may be a wrong wiring, the wrong board selection, a bad cable, a failing board or simply choosing the wrong serial port. But as you failed to provide the necessary information for us to help you, you're on your own to with that problem.
i have try uninstalled and reinstalled the chip driver, Arduino IDE, Libraries, Board Configurations in board manager(Also tried different
-Tried connecting pin IO0 to GND with jumper only
-Tried rebooting my computer
my selected board: NodeMcu 1.0(ESP-12 module )
I guess you also own exactly that board?
Does your PC recognize it?
What does "Get Board Info" (in the Tools menu) return?
BN: Unknown board
SN:upload any sketch to obtain it
i'm not sure for recognize it
The USB vendor and product IDs tell you that the board contains a CH340 USB2serial converter chip. But the corresponding board isn't recognized. So you either have a quite exotic board or your board is broken.
Post a sharp picture of it!
is that mean i need to buy a new nodemcu ?
Unfortunately it may mean that. I would first check the driver for the CH340, I don't know how well that works on Windows as I never use that OS.
