Hi dede,

In your project overlay file which you can change the default partition size for partition at start address 0X15C000 as below to change from 36KB to say 64KB

&cpuapp_rram {
  partitions {
    storage_partition: partition@15c000 {
      label = "storage";
      /* bump from 36 KB up to, say, 64 KB */
      reg = <0x15c000 0x10000>;
    };
  };
};


/ {
	chosen {
		zephyr,settings-partition = &storage_partition;
	};
};

&storage_partition {
	label = "chosen_partition";
};

The delay in answering here is due to limited staff during this period. I will try to get back to you in two or three weeks. Sorry for the inconvenience.

Hi,

How can the size of a zms partition be increased?

Thanks.

As you can see here, the settings ZMS backend is hard-coded to use one partition. Therefore, Settings will use the same partition no matter what part of the application uses Settings.

Alternatives are:

Try to increase the size of thesettings partition to check if that solves your issue.

Use another storage subsystem for your application.

Hi,

[quote user=""]1.Is the storage_partition in the flash_map_pm.h file the same as that in the nrf54l15_cpuapp_common.dtsi file?[/quote]

If you use the partition manager, the DTS one is ignored, and partition manager partitioning is used instead.

[quote user=""] Is settings_storage the area used to store ble configuration information?[/quote]

settings_storage is used for Settings, so yes.

[quote user=""]2. My nrf54l15-dk has some errors. Why is that? network/info, hub/info and first_run/check are custom configurations. I save them using settings_save_one and then reset the device, and an error E: set-value failure occurs.[/quote]

But you can store other stuff first, or?

[quote user=""]3. Through the error in the second one, I think both the custom configuration and the saved ble configuration information were saved in storage_partition, resulting in the error. So I want to ask whether storage_partition can be divided into the pairing information area of ble and the user-defined configuration information area.[/quote]

Yes, I think it shold be able to use settings for both your app and for BLE.
Try to make the settings partition larger, does that help?
