Fatal error: Waiting for packet header

[Ehh300]

I went to the wiki to setup esp8266 and it errors.

Arduino: 1.8.11 (Windows 10), Board: "LOLIN(WEMOS) D1 R2 & mini, 160 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 4MB (FS:1MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

Executable segment sizes:

IROM : 662864 - code in flash (default or ICACHE_FLASH_ATTR)

IRAM : 29988 / 32768 - code in IRAM (ICACHE_RAM_ATTR, ISRs...)

DATA : 2352 ) - initialized variables (global, static) in RAM/HEAP

RODATA : 6068 ) / 81920 - constants (global, static) in RAM/HEAP

BSS : 35280 ) - zeroed variables (global, static) in RAM/HEAP

Sketch uses 701272 bytes (67%) of program storage space. Maximum is 1044464 bytes.
Global variables use 43700 bytes (53%) of dynamic memory, leaving 38220 bytes for local variables. Maximum is 81920 bytes.

This is a generic USB upload error, but I can't tell what causes it. It might be a bad USB cable or bad USB hub etc... It is not related to anything software though. The uploader times out waiting for the right ESP response.

[Ehh300]

I'm guessing the esp8266 is bad then. Both usb port and cable work. Thanks for looking.

"Crystal is 26MHz" are we sure about that? Check the Arduino IDE uploader settings, whether there's some options about that. It might be 40MHz.

How do i do that. Never done this kind of thing.

Then in blue bar it says Done uploading

Try reducing the upload baudrate to 115200 otherwise it could be an usb to serial driver error.

[Ehh300]

What about the crystal at 26 Mhz?

What about the crystal at 26 Mhz?

I changed com port from 6 to 8 and got a different error.

I'd love to tell you exactly what's wrong, but I haven't worked with Arduino for a long time now.
There is a problem with the uploader, where it most likely is set to an incompatible setting.

Please check with the instructions here, and try to set everything as shown:
