Problem uploading code to a ESP8266 from win 11

[charly_32]

Hello, i have a problem, I'm using win 11 and try to upload a really simple sketch, it only prints the MAC address to a "Node Mcu V3. but is not letting me upload it, the error says:

I have installed twice de CH340 driver but is still not working.

I used to work on a win 10 and didn't had any problems but since I changed laptop hasn't worked.

Hi @charly_32. I know you already mentioned the CH340 driver in your post, but I would like to verify this is actually the chip on your board before continuing. The reason I am not already certain is because it is quite common for people having problems with ports or uploading to install the CH340 driver according to some advice they found on the Internet even when their board has a different USB to serial chip (meaning the advice they found was not relevant).

Please tell us which USB to serial adapter chip your Arduino board has. This is a black chip near the USB socket.

The chip will usually be identified by writing on the top. This might say something like "WCH CH340G" or "SILABS CP2102".

Examples:

WCH CH340

If it isn't clear, alternatively you can provide the link to where you bought the board from and we'll see if we can determine the chip from the product listing.
