Hi 

Is your project located in the H:\mesh\ncs\ folder?

Normally this would be the base folder for NCS, and not the project folder itself.

Hi

Thank you for your quick response.

Is your project located in the H:\mesh\ncs\ folder?

Yes.

When I used this command, the build folder appeared here.

 

west build -b nrf52840dk_nrf52840 zephyr/samples/subsys/mgmt/mcumgr/smp_svr -p -- -DOVERLAY_CONFIG=overlay-bt.conf

Hi 

I would recommend navigating to the project folder before you run west build, so that all the build files end up in the project directory itself, rather than directly under the NCS main directory.  

For signing the binaries it is recommended simply to do this as part of the build command, as shown here. 

Then all you have to do is to add the following to your build command, and the signed binaries will be created automatically:
-DCONFIG_MCUBOOT_SIGNATURE_KEY_FILE=\"bootloader/mcuboot/root-rsa-2048.pem\"

Hi，

Thank you. It works well,but I don't know the meaning of these output files.

I also can't use this command at "/h/mesh/ncs/zephyr/samples/hello_world"

These files are documented here.

What if you try to use the build command instead of the sign command, and provide the signature key file in the build command as I described earlier?
