How to program matter credentials into mass-produced products

[SunHuang]

Hi,

I refer to the method of the link below, which can generate factory_data.hex

https://docs.nordicsemi.com/bundle/ncs-latest/page/matter/nrfconnect_factory_data_configuration.html

If I want to use it for mass production, are there tools that are more convenient for Production worker to use?

Hello,

We don't provide a solution for mass generation or programming factory data because this process can differ between users. We provide the simplest solution, or recipe, which users can adjust according to their needs.

The scripts we provide can be used as a reference for creating your own scripts for generating factory data for and programming multiple devices. A Python wrapper is a possible solution if only a few parameters differ between devices.

Best regads,

Maria

Hi,

Before using generate_nrfconnect_chip_factory_data.py, I had to use the nRF connect open command tool.

Otherwise the following error will occur. How to improve it?

Hello,

The command-line build environment is set up by the Toolchain Manager application when opening a command prompt from the application UI. For a command prompt opened from elsewhere, you need to set up the build environmernt like described in the nRF Connect SDK installation documentation here (v2.7.0). You could also need to check that the command prompt calls the correct Python instance. See the overview of all tools requirements and versions here.

I notice that the nRF Connect SDK version in the Toolchain Manager and the command prompt have different nRF Connect SDK versions. Building a project from one nRF Connect SDK version in another one can cause errors (i.e. a project from v2.7.0 in v2.6.1).

BR,

Hi Maria,

Sorry,Please ignore the version issue of the screenshots.

But I don’t know how to set the "zephyrrc.cmd" parameters, such as: "GNUARMEMB_TOOLCHAIN_PATH" path.

Can you provide the correct approach?

Hi Maria,

I have successfully set up the environment, thank you for your reply
