nRF Connect SDK licenses

[turboscrew]

How do the licenses affect the possible usage of the SDK in company products?

At least:these:

 * SPDX-License-Identifier: LicenseRef-BSD-5-Clause-Nordic
 * SPDX-License-Identifier: LicenseRef-Nordic-5-Clause
 * SPDX-License-Identifier: Nordic-5-Clause

Would be nice to know about the whole SDK, if possible. The different licenses I found, are:

    SPDX-License-Identifier: Apache-2.0

Hi

For what the licenses entails, refer to the licenses themselves. I am not able to give you legal advise on how to use them.

However, here are some potentially useful links on the Topic:

About the nRF Connect SDK license

Software bill of materials: west spdx
("west spdx" does not work in the current nRF Connect SDK I think. But you should be able to fix it using the following change.

diff --git a/scripts/west_commands/zspdx/writer.py b/scripts/west_commands/zspdx/writer.py

I hope this might help

What's this?

.../v1.9.1/bootloader/mcuboot/ext/nrf/cc310_glue.c: * SPDX-License-Identifier: LicenseRef-BSD-5-Clause-Nordic

[turboscrew]

It's the same as 5-Clause Nordic License?

Hi

"LicenseRef-BSD-5-Clause-Nordic" is an error - a misprint. The correct reference should be "LicenseRef-Nordic-5-Clause".

Thank you for reporting this. I have reported it to our developers, and it will hopefully be corrected in a future release of the nRF Connect SDK.
