ESP8266 Uploading Problem

Im currently trying to upload data onto phant , but I cant. I keep getting a busy p... error on the terminal , and finally ERROR. I cant seem to figure out where exactly am I going wrong , since I am new to AT commands. Where could I possibly be going wrong , and what can I do to rectify the error ?

Do you get 'busy p' straight away or after a command? If straight away, pull the reset pin on the ESP8266 low and try again.

If it happens after a command we'd need to see the AT history, but probably better to ask at the ESP8266 forum.

Im sending a bunch of commands together. In short , Im using a predefined code , so spotting the error is diffcult. Do I still need to pull the reset pin to low?

Then start doing the AT commands command by command, and see what goes wrong. You can run https://developer.mbed.org/users/mbedAustin/code/SerialPassthrough/ on your board and forward data to ESP8266 to communicate directly from computer->ESP8266. This way you can run the AT commands over serial and figure out what goes wrong.
