I want to flash firmware into ESP8266 using Arduino Uno. I connected Rx and Tx of ESP8266 to Arduino Tx and Rx respectively via level shifter, connected GPIO0, GPIO15 to ground and Vcc, CH_PD and RESETto 3.3v and tried to download firmware using flasher. But it is displaying as " Failed to Connect". How to upload firmware through Rx, Tx of arduino, because I am not having FTDI USB-Serial.

Swap TX/RX so TX->TX and RX->RX
