Static partitioning littleFS+MCUboot+settings

[Golaz]

Hi,

I am using custom nrf52840 board with sysbuild, MCUboot+firmware loader, static partitioning, settings storage (OpenThread) and littleFS storage and I cannot get the thing to build.

This is my pm_static.ym file:

mcuboot:

  address: 0x0

  size: 0x6000

  region: flash_primary

mcuboot_pad1:

  address: 0x6000

  size: 0x200

  region: flash_primary

mcuboot_pad2:

  address: 0xA2000

  size: 0x200

  region: flash_primary

app:

  address: 0x6200

  size: 0x95E00

  region: flash_primary

firmware_loader:

  address: 0xA2200

  size: 0x5BE00

  region: flash_primary

settings_storage:

  address: 0xFE000

  size: 0x2000

  region: flash_primary

mcuboot_primary:

  address: 0x6000

  size: 0x96000

  span: [mcuboot_pad1, app]

  region: flash_primary

mcuboot_primary_app:

  address: 0x6200

  size: 0x95E00

  span: [app]

  region: flash_primary

mcuboot_secondary:

  address: 0xA2000

  size: 0x5C000

  span: [mcuboot_pad2, firmware_loader]

  region: flash_primary

mcuboot_secondary_app:

  address: 0xA2200

  size: 0x5BE00

  span: [firmware_loader]

  region: flash_primary

littlefs_storage:

  address: 0x9C000

  size: 0x6000

  region: flash_primary

sram_primary:

  address: 0x20000000

  size: 0x40000

  region: sram_primary

Here is the relevant part of DTS:

/ {

    chosen {

        zephyr,flash = &flash0;

        zephyr,settings-partition = &storage_partition;

    };

    fstab: fstab {

        compatible = "zephyr,fstab";

        lfs: lfs {

            compatible = "zephyr,fstab,littlefs";

            mount-point = "/lfs1";

            partition = <&littlefs_partition>;

            automount;

            read-size = <16>;

            prog-size = <16>;

            cache-size = <64>;

            lookahead-size = <32>;

            block-cycles = <512>;

            read-only;

        };

    };
};

&flash0 {

    partitions {

        compatible = "fixed-partitions";

        #address-cells = <1>;

        #size-cells = <1>;

        boot_partition: partition@0 {

            label = "mcuboot";

            reg = <0x00000000 DT_SIZE_K(24)>;

        };

        slot0_partition: partition@6000 {

            label = "image-0";

            reg = <0x00006000 DT_SIZE_K(600)>;

        };

        littlefs_partition: partition@9c000 {

            label = "littlefs";

            reg = <0x0009c000 DT_SIZE_K(24)>;

        };

        slot1_partition: partition@A2000 {

            label = "image-1";

            reg = <0x000A2000 DT_SIZE_K(368)>;

        };

        storage_partition: partition@fe000 {

            label = "storage";

            reg = <0x000fe000 DT_SIZE_K(8)>;

        };

    };

};

And here is the error that is generated:

Partition 'settings_storage' is not included in the dynamic resolving since it is statically defined.

Please I need help. This is too much.

Solution: firmware_loader region must be placed directly after app region.
