Matter: please show me the detailed steps to add diagnostic logging functionality to the Matter sample project

[paper555]

I'm trying to add diagnostic logging functionality to my Matter project using SDK version v3.0.1. I followed the steps outlined here: (https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/protocols/matter/getting_started/advanced_kconfigs.html#diagnostic_logs), but I'm encountering compilation errors.

Here's what I've done:

1. Added the Diagnostic Logs cluster in ZAP Tool
2. Added the following configurations to prj.conf

            CONFIG_NCS_SAMPLE_MATTER_DIAGNOSTIC_LOGS=y

            CONFIG_NCS_SAMPLE_MATTER_DIAGNOSTIC_LOGS_CRASH_LOGS=y

            CONFIG_NCS_SAMPLE_MATTER_DIAGNOSTIC_LOGS_REMOVE_CRASH_AFTER_READ=y

           CONFIG_NCS_SAMPLE_MATTER_DIAGNOSTIC_LOGS_END_USER_LOGS=y

           CONFIG_NCS_SAMPLE_MATTER_DIAGNOSTIC_LOGS_NETWORK_LOGS=y

           CONFIG_LOG_MODE_DEFERRED=y CONFIG_LOG_RUNTIME_FILTERING=n

However, when I try to build the project, it fails with compilation errors.

          

 

Could you provide me with a sample project?

Hi,

The reason is that copying configuration from snippet to .conf is not enough, as snippet does one more thing beside of that. It additionally includes dts overlay that configures retention sections: https://github.com/nrfconnect/sdk-nrf/blob/main/snippets/matter-diagnostic-logs/snippet.yml#L20 (in particular this is what is missing according to the compilation error). Here is an overlay file that should be used for L15: https://github.com/nrfconnect/sdk-nrf/blob/main/snippets/matter-diagnostic-logs/boards/nrf54l15dk_nrf54l15_cpuapp.overlay
