esptool.FatalError:Failed to connect to ESP8266: TIMED OUT WAITING FOR PACKET HEADER
Title
Question
Arduino: 1.8.11 (Windows 7), Board: "Generic ESP8266 Module, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), no dtr (aka ck), 26 MHz, 40MHz, DOUT (compatible), 1MB (FS:64KB OTA:~470KB), 1, nonos-sdk 2.2.1+100 (190703), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

Executable segment sizes:


IROM   : 241152          - code in flash         (default or ICACHE_FLASH_ATTR) 


IRAM   : 26836   / 32768 - code in IRAM          (ICACHE_RAM_ATTR, ISRs...) 


DATA   : 1264  )         - initialized variables (global, static) in RAM/HEAP 


RODATA : 1076  ) / 81920 - constants             (global, static) in RAM/HEAP 


BSS    : 24968 )         - zeroed variables      (global, static) in RAM/HEAP 


Sketch uses 270328 bytes (28%) of program storage space. Maximum is 958448 bytes.
Global variables use 27308 bytes (33%) of dynamic memory, leaving 54612 bytes for local variables. Maximum is 81920 bytes.

Answers:

Did you press the push button connected to RST pin of ESP8266 while it was showing Connecting.....

Ideally now it should work. But if you are getting the same error again, I request you to dismantle the connection and connect it again and run the code one more time.

tried on different pc's and used a new esp8266, still the problem persists

Connect 3.3V external power supply to ESP8266 module instead of giving from arduino. And do the experiment.
