Xiao boards: "Property 'upload.tool.serial' is undefined"

Development Tools IDE 2.x
12

Hi @brainmaiden. The bug and general nature of the fix is the same, but the details are different because this time the bug is in the "Seeed nRF52 mbed-enabled Boards" platform instead of the M5Stack platform.

I'll provide instructions for the fix:

  1. Open the file at the following path using any text editor:
    /Users/Scound-Bast/Library/Arduino15/packages/Seeeduino/hardware/mbed/2.7.2/boards.txt
  2. Add this line anywhere in the file:
    xiaonRF52840.upload.tool.default=nrfutil
  3. Save the file.
  4. If the Arduino IDE is running, select File > Quit from the Arduino IDE menus.
  5. Start the Arduino IDE.
    ⓘ The restart is done to make the IDE recognize the change to the boards.txt file.

Now try uploading again. Hopefully the error will no longer occur.

Please let me know if you have any questions or problems while following those instructions.
