Hi,

NCS uses the same build system as Zephyr, so all of our samples come with a CMakelist.txt file. Whether you use West or cmake commands to build projects is up to you.

In case you want to use west West, note that the "west build" does allow you to specify additional Cmake arguments. See "Generate and Import an Eclipse Project" for how you can use these to generate Eclipse projects.

[quote user="robertfirma"]Why we could not use cc31X HW in Zephyr apps?[/quote]

You could, but to do so, you would need to integrate mbedtls with the propriatery cc310 backend as we have done it in NCS. And please keep in mind that NCS doesn't prevent you from selecting the SW based crypto libraries from Zephyr, it's merely giving your more options to choose from.

Best regards,

Vidar

Hi,

Do you have any link to NCS sample app that using only cmake (not west) to build app?

I mean, that CMakeList.txt file include which ZEPHYR_MODULES is in project and not west build.

Why we could not use cc31X HW in Zephyr apps?

Best regards,

Robert

Hello Robert,

NCS uses the same build system as Zephyr, so it should really be no different. It's optional to use west as the build command.

[quote user="robertfirma"]It will be nice and more transparent that Zephyr moduls is used for nrfxlib.[/quote]

Yes, but then you won't be able to utitilize the cc310 for HW accelerated crypto on the nRF52840.

Hi,

I'm using cmake for build system. And as I know NCS use west in front of cmake. West is not compatible with Eclipse CDT.

I could try to do, but I'm prepare with your help to import nrfxlib into clasic Zephyr project. I think most of users will like that.

I can send you prj.conf file and CMakeList.txt file.

I'm also discover that CONFIG_NORDIC_SECURITY_BACKEND must be enabled. But then MbedTLS module must be included. And here is another problem. Nrfxlib could not find mbedtls modul. It will be nice and more transparent that Zephyr moduls is used for nrfxlib.

Best regards,

Robert

Hi,

Could you try to build your project against NCS v1.4.0 and see if you get the same result? I'm not sure if you will be able to easily integrate the Softdevice link layer with Zephyr.

Best regards,
