ESP8266: Timed out waiting for packet header
Posted: Mon May 11, 2020 2:42 pmHello,
Today i bought 2 NodeMCU ESP8266 and managed to get the first one working without any problems.
But when i try to upload something to the other board i get this

Executable segment sizes:
IROM : 228492 - code in flash (default or ICACHE_FLASH_ATTR)
IRAM : 26792 / 32768 - code in IRAM (ICACHE_RAM_ATTR, ISRs...)
DATA : 1248 ) - initialized variables (global, static) in RAM/HEAP
RODATA : 688 ) / 81920 - constants (global, static) in RAM/HEAP
BSS : 24880 ) - zeroed variables (global, static) in RAM/HEAP
Sketch uses 257220 bytes (24%) of program storage space. Maximum is 1044464 bytes.
Global variables use 26816 bytes (32%) of dynamic memory, leaving 55104 bytes for local variables. Maximum is 81920 bytes.

esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header

And I havent changed anything. After that I deleted the esp8266 package and reinstalleed 2.6.0 just to see if anything changes but still doesnt work.
The COM is correct. Board is selected from tools>boards.
Can the unit be damaged ?? and i see LED flashing when it tryies to connect.
