getting error "ERROR: source directory –b does not exist" when "west build –b nrf5340dk_nrf5340_cpunet –p"

[Kenny Lee litepoint]

C:\ncs\v2.6.2\nrf\samples\nrf5340\empty_app_core>west build –b nrf5340dk_nrf5340_cpuapp –p

while building the image, getting error:

ERROR: source directory –b does not exist
FATAL ERROR: refusing to proceed without --force due to above error

I checked the zephyr\board that the target board does exist.

C:\ncs\v2.6.2\zephyr\boards\arm\nrf5340dk_nrf5340

I used to be able to build without errors.

One major event for my PC is upgrading from windows10 to windows11. 

Thanks.

Hello Kenny,

It's due to formatting, -b is for designating a board directory. I believe it is seeing the --b and associating it with --build-dir. Please try the following:

west build -p -b nrf5340dk/nrf5340/cpuapp
