Cannot upload from Arduino IDE 2.0.3 and esp8266 3.1.1

I'm running macOS 13.1 and Arduino IDE 2.0.3 with esp8266 version 3.1.1.

I've configured the Arduino IDE according to the Getting Started document, or as close as I can given that the IDE is a little different now.

When I reset the board and then press "Upload", it eventually fails with:

esptool.py v3.0
Serial port /dev/cu.usbmodem32123101
Connecting........_____.
A fatal esptool.py error occurred: Timed out waiting for packet header

Are there other settings that need to be configured? Or is there a version of the esp8266 board package that is known to work?

I can repeat this with Arduino 2.0.3 and esp8266 3.1.1 on a Windows machine.

I was able to get it working by changing the esp8266 version to 2.0.0, and uploading the 'blinkydemo' sketch with the following settings:
board: generic esp8266 module
reset method: nodemcu
upload speed: 512000

Can you try these settings and see if they work for you?

(edit: wrong version, I used 2.0.0 not 2.7.4)

Thanks. I was also able to get it to work with an older version of the esp8266 package for the Arduino IDE. I think it depends on the version of esptool included. See espressif/esptool#827
