Flashing firmware to ESP-12E

Hi.
That’s usually not an error. 
Do you get any more information besides that?

Hi.
You usually get those lines after uploading the code. It is not an error.
Unless you have additional messages.
To run the code, just press the on-board RST button.
If you are not able to run the code, paste a print screen of your error. You can use a link to google drive, dropbox, imgur or others.

Hi again.
That means that the ESP board is constantly rebooting.
This usually happens on one of these scenarios:

• something is wrong with the code
• the ESP doesn’t have enough power
• there is some sort of hardware problem:
  • like the board is faulty;
  • there is a short circuit;
  • there is a something connected to the ESP in the wrong way.

Can you tell me what code are you trying to upload and if you have something connected to your board?
What is exactly the board model that you are using?
Regards,
Sara

I am able to execute hello word code, but not simple code in which board is connected to Wi-Fi & button press then LED blinking code. 
I am using below board

ESP WROOM 32 MCU Module

Hi.
Can you give more information? It is very difficult to find out what might be wrong without more information.
What “hello world” code are you talking about?
In your Arduino IDE,  go to File > Examples > WiFi > WiFiScan. Test that example and see if it works.
Test other basic examples provided in the Arduino IDE and see if those work.
If the basic examples from there don’t work for your board, there is definitely something wrong with the hardware.
