Custom framework and toolset for Arduino ESP8266 3.0.0

Development Platforms
1

Hi,

I am trying to get esp8266 framework v3.0.0 to work. I’ve got it working in classic Arduino IDE, but I want to use it in Platform IO, as I love both VSCode and PIO. But unfortunately, it seems like framework is working OK, but the tools do not change - in result I’m getting compilation errors about C++17.

Repro steps are:

  1. Create new empty project for Wemos D1 Mini, for ESP8266 Arduino Platform
  2. Add custom framework to platformio.ini

[env:d1_mini]
platform = espressif8266
board = d1_mini
framework = arduino
platform_packages =
framework-arduinoespressif8266 @ GitHub - esp8266/Arduino: ESP8266 core for Arduino

  1. Try to compile
  2. Get

Is there a way to force custom tools as well?

You are already doing this for the framework.

See docs. The used compiler is still

So just lookup available versions at bintray and e.g. say

[env:d1_mini]
platform = espressif8266
board = d1_mini
framework = arduino
platform_packages =
   framework-arduinoespressif8266 @ https://github.com/esp8266/Arduino.git
   toolchain-xtensa@2.100100.200706

to give you GCC 10.1.0.

This is exactly what I was looking for! Awesome, thank you very much. I just didn’t know what to specify after the @

It seems the bintray files are missing or deteled?? i.e. this one: Service End for Bintray, JCenter, GoCenter, and ChartCenter | JFrog

Any idea on where to look for xtensa toolchain versions and which GCC they include?

Just go two directectories up in the link. You’ll then see for yourself that it’s now available under Service End for Bintray, JCenter, GoCenter, and ChartCenter | JFrog and packages like toolchain-xtensa-windows are available.
