example of RRAM on NRF54L15

[hqiu]

Hi,

Now we are using NRF54L15 to develop an indoor GW. We need use NRF54L15 to keep some key information after power off. Since NRF54L15 is a new PN, we didn't see any sample code on NCS 2.9.1 about how to use RRAM. Could you kindly point me where I can find some sample code about this RRAM? Thanks.

Hi,

 

You have different filesystems, and settings subsys, that you can use to store data.

For instance:

* https://github.com/nrfconnect/sdk-zephyr/tree/main/samples/subsys/fs/littlefs

* https://github.com/nrfconnect/sdk-zephyr/tree/main/samples/subsys/fs/zms 

You can also run simpler flash driver, like this sample:

Kind regards,

Håkon
