New board extensions not supported by VSCode nRF extension?

[pcspets]

Hello

When following the guidline of a new way to extend boards, VSCode "Add Build Configuration" is blank. Am I doing something wrong or this is not yet supported by nRF VSCode extension?

Attached is a sample project with the following "board.yaml":

board:
  extend: nrf52840dk
  variants:
    - name: test
      qualifier: nrf52840

extended_board_test.zip

The support has arrived - thank you! But for some reason it fails to compile with the following CMake error:

  ARCH not defined.  Check that BOARD=nrf52840dk, is selecting an appropriate
  SoC in Kconfig, SoC=, and that the SoC is selecting the correct
  architecture.

Am I doing something wrong?

PS. The sample project needs one fix before compiling - "nrf52840dk_nrf52840dk_test.dts" needs the following mandatory content:

/dts-v1/;

/ {
};
