Hi LeoChen ,

I can't expand the Kconfig tree on double-byte win10, it always show the circle to run.

Do you meet the same problem on double-byte windows?

Hi Chen,

It should be the solution, zephyr do the same modification in the github repo.

Hi,

In the file scripts/list_boards.py,

Please change:
with board_yml.open('r') as f:
to:
with board_yml.open('r', encoding='utf-8') as f:

This change resolves the build error on my side.

Leo

Hi,

Thanks a lot for the test and good to know it can work.

one question : why NCS v2.8.0 works well in the same windows11 environment ? is there any config to set to make the ncs v2.9.0 works in the same windows11 environment. Thanks !

Best Regards

Frank

Hi,

I try to build NCS v2.9.0 sample in English Win10 virtual machine, it can build successfully, so the root cause is double-byte Win10 environment.

Hi,

I have the same error, and use the "west boards" command can reproduce the problem. I guess it may just happen in double-byte Windows environment.
