Flashing ESP8266 Firmware

So my esp is connected to UNO and when I am trying to flash the firware I cant but through serial monitor I can connect to it.|500x136

It sort of looks like you are trying to open a com port that is already in use ?

I don't use an Arduino to program the ESP's but a USB serial ttl converter and I never have issues with that method but I guess using an Arduino is similar enough.

For the firmware flashing on ESP's maybe try some of the more specific flashing tools available.

ESP8266FLASHER ESPTOOL ESP_DOWNLOAD_TOOL_V2.4

And many more

You didn't say what firmware you want to put on the ESP ? There are a few

e.g. LUA, AT, EASYESP, NODEMCU etc inc subversion's such as float, integer etc.

Maybe a little more detail would help ?

Well I just needed to close the serial monitor and it worked.
