Storing to flash storage

[SpencerEtn]

Hi, 

We're working on the nrf52833 chipset and were wondering how to add more data to the flash storage. I've traced the calls of load_settings() in the main and where fcb_init() is called in bt_enable() but it seems to just know where flash data is. There's no struct or file that actually has data that I can manipulate / add to. Ideally, we would like to be able to see where the bluetooth configuration data is in the flash. Any pointers to the right direction or advice would be appreciated.

Thanks,

Spencer

Hi Spencer

To use NVS, you need to configure for this.

I advise you to compare the prj.conf and your project and the NVS sample I linked previously to find what configuration works best for you project.
But the specific error you get is probably due to missing:

CONFIG_NVS=y

Hi Sigurd,

Sorry I don't know how I missed that.. I have updated my prj.conf file to add all the other missing config flags as the sample project. Unfortunately I am still getting the same error... I appreciate all your help thus far!

Hi Spencer

At this point, I would be better able to help you if I could try to run the code myself.
Are you able to make a smallest possible sample to replicate the problem, then upload it as a zip to this site?

If do not want it to be public, I could make the case private; Let me know if I should.

Hey Sigurd,

I thought I posted an update but I guess it didn't post. I figured out the error with the undefined references were because the nvs.h file was not linked to any nvs.c file in the zephyr library. The issue I have now is when adding the nvs.c file to be part of the libzephyr.a project it's not able to read the other library files like <driver/flash.h>. I've looked at the CMakeLists but didn't find anything there. I know this is not so much Nordic related but do you know how to add to the library correctly? 

Thanks,

Spencer

This seems wierd.

Are you able to build and run the NVS sample I linked to earlier?
Cause if you are Zephyr should be able to handle the NVS functionality.

I am able to build this sample, without modifying any libraries.
