Hi Community,

I`m using a ESP8266 on a D1mini. In the past all was working fine. So, I installed the stuff correctly, I guess. But then there was a update (for some of my librarys) available and I executed it. After that, I get the message, that the Board d1 (platform esp8266, package esp8266) is unknown und the compiling for the Board WeMos D1 R1 failed.

I checked already all the settings in the "Arduino" additional boardmanager-URL, Tools, Sketch-Libraries...

What could the reason/solution for my problem?

Greetings

The "Board ... is unknown" error occurs when a Boards Manager installation of a different version of a hardware package fails to completely uninstall the previous version. Here's how you solve it:
  • Click the link on the line following File > Preferences > More preferences can be edited directly in the file. This will open the Arduino15 (or similar name depending on OS) folder.
  • Navigate to the packages/esp8266/hardware/esp8266 folder.
  • You will see two folders. One is named by the version of the package you currently have installed, the other is named by the version of the package you previously had installed. Delete the folder with the previous version name. Please be very careful when deleting things on your computer. When in doubt back up!
