Can USB MSD and USB DFU coexist in the same project?

RE: Can USB MSD and USB DFU coexist in the same project?

Hi,

[quote user="Thoraz"]I have the same problem if I create a new DFU sample project (nothing about MSD) with no changes except for my custom board and the CONFIG_PINCTRL=y in the conf.prj . Maybe is off topic here, but I'm beginning to wonder if the definition of my board device tree is wrong somehow.[/quote]

Since this new question is not related to MSD, I would suggest that you open a new ticket.

You can read more about custom boards in the documentation. There are some additional resources about boards and devices, creating new board and board porting guide.

Best regards,
Dejan

It seems that FAT FS on external flash is currently not working with partition manager.
You can find more information in this discussion.

Hi dejans, ok for your precious information, but what about this

[quote userid="112991" url="~/f/nordic-q-a/104108/can-usb-msd-and-usb-dfu-coexist-in-the-same-project/447638"]I've just tried to create a new DFU project from template. I didn't change nothing, only added my custom board and the CONFIG_PINCTRL=y in the conf.prj . Nothing else. And I can't build again. It seems that the qspi for the NOR flash is involved in some way. Is it possible?[/quote]

Ok, I'll have a look. Thanks.

I've just tried to create a new DFU project from template. I didn't change nothing, only added my custom board and the CONFIG_PINCTRL=y in the conf.prj . Nothing else. And I can't build again. It seems that the qspi for the NOR flash is involved in some way. Is it possible?

But if I exclude commenting on the QSPI part in my device tree file

&qspi {
	status = "okay";
	pinctrl-0 = <&qspi_default>;
	pinctrl-1 = <&qspi_sleep>;
	pinctrl-names = "default", "sleep";

	mt25qu512: mt25qu512@0 {
		compatible = "nordic,qspi-nor";
		reg = <0>;
		writeoc = "pp4io";
		readoc = "read4o";
		sck-frequency = <8000000>;
		jedec-id = [20 bb 20];
		sfdp-bfp = [
			e5 20 fb ff  ff ff ff 1f  29 eb 27 6b  27 3b 27 bb
			ff ff ff ff  ff ff 27 bb  ff ff 29 eb  0c 20 10 d8
			0f 52 00 00  24 4a 99 00  8b 8e 03 e1  ac 01 27 38
			7a 75 7a 75  fb bd d5 5c  4a 0f 82 ff  81 bd 3d 36
		];
		size = <536870912>;
		has-dpd;
		t-enter-dpd = <10000>;
		t-exit-dpd = <35000>;
	};
};

and I don't use the overlay file

&mt25qu512 {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		flash_storage_partition: partition@0 {
			label = "flash-storage";
			reg = <0x00000000 0x04000000>;
		};
	};
};

/ {
	msc_disk0 {
		compatible = "zephyr,flash-disk";
		partition = <&flash_storage_partition>;
		disk-name = "NAND";
		cache-size = <4096>;
	};
};

it builds successfully.

Maybe there is something wrong in the definition of my custom board?

Thanks Dejan for your response. Perhaps I should have specified that I'm working on a custom board which mounts an external NOR flash (interfaced througth qspi, as in the 52840 DK) for the MDS feature. So I'm working with a custom device tree in VS Code nRF Connect environment. Maybe is better if I share with you my whole project here.

When you say to replace CONFIG_DISK_DRIVER_FLASH=y with CONFIG_DISK_DRIVER_RAM=y, doesn't it means to use the RAM instead of external NOR flash? Can you explain your replacing?

Hi,

I have tried to reproduce your issue using NCS v2.3.0. Build failed when I used your configuration, but I did not see the same error as you when CONFIG_DISK_DRIVER_FLASH=y was included in prj.conf. I got mass sample to successfully build with your configuration by replacing CONFIG_DISK_DRIVER_FLASH=y with CONFIG_DISK_DRIVER_RAM=y. I used following build command:

west build --build-dir <your_project_folder>/build <your_project_folder> --pristine --board nrf52840dk_nrf52840 --no-sysbuild -- -DNCS_TOOLCHAIN_VERSION="NONE" -DCONF_FILE="<your_project_folder>/prj.conf" -DDTC_OVERLAY_FILE="boards/nrf52840dk_nrf52840.overlay"

Additionally, I needed to replace #include<zephyr/usb/class/usbd_msc.h> with #include<zephyr/usb/class/usb_msc.h> in the main.c file.

Dejan
