Upload issue in Uno+WiFi R3 AtMega328p+NodeMCU ESP8266 32mb Memory USB-TTL CH340

I recently bought this board: UNO R3 + WiFi ATmega328P+ESP8266 (32Mb memory) USB-TTL CH340G for Arduino Uno NodeMCU WeMos ESP8266

Unfortunately I can't upload my sketch (for testing it is the blink sketch) to the board and have no idea what's the reason.

I am new to Arduino and IDE

Please suggest Step by Step process !

using WIN10 and IDE Arduino 1.6.5 .

Any help appreciated

error:
esptool v0.4.8 - (c) 2014 Ch. Klippel ck@atelier-klippel.de
setting board to ck
setting baudrate from 115200 to 115200

Looks like a simple case of selecting the wrong COM port.

I feel like I'm on a roll with this today, but you did actually install the ch340 driver right? It is listed in the documents section of the page mentioned above. Everything will look fine, but uploads will nt work if you don't install the ch340 USB chip driver.

Then yes you also need to configure the DIP switches depending on which module you are trying to flash.
