Settings API Example Compiling, but not working

[Jim Logsdon]

I'm attempting to use the Settings API save and retrieve data from nRF52832 FLASH memory.  I can build and run the example application provided in the Settings documentation (link below)

https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/services/settings/index.html#example_persist_runtime_state

The entries in my prj.conf file are:

CONFIG_SETTINGS=y

CONFIG_REBOOT=y

The application runs and reboots as intended, but the write or read from FLASH is not working.   Here is the serial port output:

*** Booting nRF Connect SDK v2.9.0-7787b2649840 ***
*** Using Zephyr OS v3.7.99-1f8f3dc29142 ***

What else must I do to make the Settings API correctly save and restore data?

Thanks

Hi James,

It is hard to know why the settings save and restore is not functioning without knowing the context and code you are using to do that. Can you share the code snippets of the save and restore being used and tell my why you were expecting so many resets?
