I am trying to upload a sketch and getting below error:

error: failed reading bytewarning: espcomm_send_command: cant receive slip payload datawarning: espcomm_sync failederror: espcomm_open failederror: espcomm_upload_mem failed.

Connections:

TX - TXCH_PD - 3.3 VRX - RXVCC - 3.3GPIO GNDGND - GND

Before uploading the sketch I have reset the arduino and ESP and selected board as ESP8266 and baud rate as 115200 but still getting the same error.

You don't say what you're using to program it (an FTDI board? the USB adapter on an Arduino?) but you probably want to connect

TX - RXRX - TX
