Mass storage initialization error with nsib and mcuboot

Mithilesh Yadav

Board: nRF52840Dk

ncs: v2.3.0.

Hi, I am working on a project in which i need to update bootloader itself and application from the external flash. I also need to make partition where i can store my files using FatFs file system.

My project configuration and overlay setting are below:

CONFIG_STDOUT_CONSOLE=y

#USB related configs
CONFIG_USB_DEVICE_STACK=y
CONFIG_USB_DEVICE_PRODUCT="Zephyr MSC sample"

/delete-node/ &boot_partition;
/delete-node/ &slot0_partition;
/delete-node/ &slot1_partition;

&flash0 {
	partitions {
		boot_partition: partition@0 {
			label = "mcuboot";
			reg = <0x000000000 0x00010000>;
		};
		slot0_partition: partition@10000 {
			label = "image-0";
			reg = <0x000010000 0x0000e8000>;
		};
	};
};

&mx25r64 {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		slot1_partition: partition@0 {
			label = "image-1";
			reg = <0x000000000 0x0000e8000>;
		};
		external_flash: partition@e8000 {
			label = "external flash";
			reg = <0x0000e8000 0x000718000>;
		};
	};
};

/ {
	chosen {
		nordic,pm-ext-flash = &mx25r64;
	};
	msc_disk0 {
		compatible = "zephyr,flash-disk";
		partition = <&external_flash>;
		disk-name = "NAND";
		cache-size = <4096>;
	};
};

When i am running the code then getting error of msc init:

Attempting to boot slot 0.
Attempting to boot from address 0x9200.
Verifying signature against key 0.
Hash: 0x8f...3b

Please help me, what I am doing wrong.

Thanks.

    Okay.

    Hieu said:
    The pull request you linked seems internal to Sigvartmh's repository. The support for flash disk API should have been completed in NCS v2.5.0.

    Without this patch, I am getting code build error.

    Hieu said:
    I see that the change to swap_misc.c was provided by Sigvartmh below. I believe Sigvartmh is investigating whether the change has to be made permanently or not, so we cannot confirm whether it will be merged in NCS yet.

    Please let me know, if you get any solution for the same.

    With things like this, I think it is reasonable for you to move forward with a cherry-picking version of NCS v2.3.0. To sync up, are there any issues left with that setup? 

    Next, just for the purpose of providing information, and not suggesting a different direction, I want to explain about the support of FAT FS with Partition Manager in NCS v2.5.0.

    Sigvartmh's own PR 38 contains experimental support to automatically create a FAT FS partition. In NCS v2.5.0, without that patch, you will still be able to setup a FAT FS partition manually using a static Partition Manager configuration YML.

    While the sample code in PR 11802 doesn't work. I can get FAT FS working with Partition Manager just fine using a slightly different pm_static.yml file like this:
    (note the affiliation attribute of the storage partition)

    app:
  address: 0x00000000
  end_address: 0x000f0000
  region: flash_primary
  size: 0x000f0000
storage:
  address: 0x000f0000
  end_address: 0x00100000
  region: flash_primary
  size: 0x00010000
  
  affiliation: 
    - disk
  extra_params: {
    disk_name: "SD",
    disk_cache_size: 4096,
    disk_sector_size: 512,
    disk_read_only: 0
  }

    I have checked with the author, and the issue is registered and in investigation. However, right now, the feature works as above.
