Storing nrf_log output (NRF_LOG_INFO) in internal file system .

[xcepti0n]

Hi,

I am beginner in nordic development. I will be using using FreeRTOS with nordic ( if that matters).

Requirement: I need to store logs in internal file system.

Device - nrf52840 DK,

SDK - nRF5_SDK_15.3.0

I understand that nrf_log output is limited to backends - UART/RTT/CLI, But I want to log into a file in internal file system.

Please tell if more details are required.

So you said what your requirements are, but what's your question?

[xcepti0n]

My question is - is it feasible to store logs in internal file system? If so is there any other way than using nrf_log? 

[Andy]

Well, it is feasible. Whether that's a good idea or not is a different question.

And yes, there are a number of ways to do what you want to do. In the end what you want to do is just to store strings in flash. You don't need nrf_log for that.

I didn't want to reinvent the wheel so, I wanted to explore something Nordic SDK already provides.

By the way, I also needed the log levels, log buffer, etc. Sorry if I wasn't clear before. I was asking if I can use nrf_log for storing logs in internal file system.

Thanks for the quick reply.

I guess you could write a new "backend" which writes to flash instead of UART/RTT...
