I see the CONFIG_BT_LL_SW_SPLIT=y is used in your project. That config is not supported since v2.8.0. To use the Zephyr Bluetooth LE Controller, use the bt-ll-sw-split snippet (see Snippets). See https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/releases_and_maturity/migration/migration_guide_2.8.html#bluetooth_le.

devzone.nordicsemi.com/.../MyProject.7z Found a way around the upload error by switching browsers. Attached is the entire directory (zipped) of the project. My local path for it is D:\Projects\NordicExp so I suspect if you put it somewhere else some of the internal paths will need to be updated.

RE: undefined reference to `__device_dts_ord_88'

Then, I would suggest you use that peripheral sample as the base for your application since you said you can build it without issue.

I still get an error "URL protocol is not allowed: D:/Projects/NordicExp/MyProject.7z" when trying to upload.

RE: undefined reference to `__device_dts_ord_88'

Amanda Hsieh — Tue, 24 Feb 2026 21:08:12 GMT

You can upload with .7z

RE: undefined reference to `__device_dts_ord_88'

Will_20241202 — Tue, 24 Feb 2026 20:31:19 GMT

When I try to use that tool it says "URL protocol is not allowed: D:/Projects/NordicExp/MyProject.zip"

I tried change the file extension to BMP, JPG, PNG, etc. and the error message doesn't change.

I originally tried using Windows style path with back slashes and it errors with "Invalid URL: D:\Projects\NordicExp\MyProject.zip"

Will_20241202 — Tue, 24 Feb 2026 17:28:30 GMT

I've managed to cut down the broken project as far as I can. Still produces the same error. Not seeing any way to upload it to the forum. Seems to only let me upload valid image or video files, but not a zip (even if I change the extension). Is there another method for sharing?

If you ensure that the board path is correct, then I have no idea.

Could you provide a simple project to help reproduce the issue?

RE: undefined reference to `__device_dts_ord_88'

Will_20241202 — Mon, 23 Feb 2026 17:04:39 GMT

Where is the board path specified? The only place I'm aware of is on the add/edit Build Configuration page there is a section for "Board target", and I chose the "generic_nrf52832_v2/nrf52832" option from the drop down menu.

Looking through the failed build log I do see lines like

-- Found BOARD.dts: D:/Projects/<redacted>/repositories/<redacted>/boards/Generic/generic_nrf52832_v2/generic_nrf52832_v2.dts

...

Loaded configuration 'D:/Projects/<redacted>/repositories/<redacted>/boards/Generic/generic_nrf52832_v2/generic_nrf52832_v2_defconfig'

which agrees with where I think it should be looking.

RE: undefined reference to `__device_dts_ord_88'

Amanda Hsieh — Mon, 23 Feb 2026 16:56:37 GMT

Sorry, I mean the board path.

I don't think you need those arguments. It uses sysbuild by default since NCS v2.8.0.

Can you give a little more detail on what this means?

As an additional data point, I discovered that when trying to build with SDK v2.8.0, the "Extra CMake arguments" specified on the add/edit Build Configuration page are not being applied (they were in SDK v2.7.0 based on the build logs I kept). Worse still, after I add them using that page and press the Generate button to create the Build Configuration for later building, if I edit the Build Configuration for that target they have all been removed!

For reference, the arguments I was trying to include using this method were:

-Dmcuboot_CONF_FILE=D:/Projects/<REDACTED>/repositories/<REDACTED>/sysbuild/mcuboot/prj.conf
-Dmcuboot_EXTRA_CONF_FILE=C:/ncs/v2.8.0/nrf/subsys/partition_manager/partition_manager_enabled.conf
-DCACHED_CONF_FILE=D:/Projects/<REDACTED>/repositories/<REDACTED>/prj.conf

Again to be clear, these were fine using SDK/toolchain v2.7.0 and appeared in the build logs output by VS Code to its "terminal" window. Looking at the failing build logs for SDK/toolchain v2.8.0 they are not even being passed as arguments.

One significant difference between the samples and my application is the usage of mcuboot. Don't know how/if that might change things, but figured it was worth bringing up.

I was able to build the 5734.peripheral.7z using VS Code without issue.

I'm not sure how to build using the West commands. Trying them from either a command line (cmd.exe) or a Powershell within VS Code both result in the error message

Completely deleted the build folder and recreated the build configuration from scratch. No change, still gives the same error. I removed the files from my board directory and replaced them with the files from the 7z you linked above and I'm still getting the __device_dts_ord error for the /soc/radio@40001000/bt_hci_sdc

RE: undefined reference to `__device_dts_ord_88'

Amanda Hsieh — Thu, 19 Feb 2026 16:19:41 GMT

I cannot reproduce with your files. Try to delete the build folder and build again.

Here is the test file: devzone.nordicsemi.com/.../generic_5F00_nrf52832_5F00_v2.7z.

Beware that this code/configuration is not fully tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.

Not sure how to attach a file so code is inline below. These are based off creating a new board using the nRF Connect plugin for VS Code, then adding in bits from the older definition that used the HWMv1. There are comment markers indicating where I cut/pasted code from the GitHub file mentioned previously.

I created a custom board file and built it for zephyr\samples\bluetooth\peripheral, but I cannot reproduce the issue.

Could you provide your custom board file?

[quote userid="77782" url="~/f/nordic-q-a/127039/undefined-reference-to-__device_dts_ord_88/561400"]You can refer to https://github.com/nrfconnect/sdk-zephyr/blob/v3.7.99-ncs1/dts/arm/nordic/nrf52832.dtsi to add or duplicate it for your custom board.[/quote]

That is the same file that you previously linked to. It does not look anything like either the .dts or the .dtsi files generated by the nRF connect tool. Specifically, there is no "chosen" section in the generated .dtsi file, but there is a "chosen" section in the .dts file, but no mention of "cpus" or "soc" sections. I tried inserting the "cpus" and "soc" sections from the github file into my .dts file immediately after the "chosen" section (similar to where it is in the Github file), and I still get the exact same build error of undefined reference to `__device_dts_ord_88'

What exactly do I need to put (and where) in the .dts and .dts files to fix this problem?

I'm still not clear on what is necessary and what isn't based on that file. To simplify, I used the nRF Connect plugin to "Create a new board" and the files it generates do not look anything like the above. The .dts file is just

/dts-v1/;
#include <nordic/nrf52832_qfaa.dtsi>
#include "fake_board-pinctrl.dtsi"

/ {
	model = "Custom Board auto generated by nRF Connect for VS Code";
	compatible = "generic,fake-board";

	chosen {
		zephyr,sram = &sram0;
		zephyr,flash = &flash0;
		zephyr,code-partition = &slot0_partition;
	};
};

&flash0 {
	partitions {
		compatible = "fixed-partitions";
		#address-cells = <1>;
		#size-cells = <1>;

		boot_partition: partition@0 {
			label = "mcuboot";
			reg = <0x00000000 DT_SIZE_K(48)>;
		};

		slot0_partition: partition@c000 {
			label = "image-0";
			reg = <0x0000c000 DT_SIZE_K(220)>;
		};

		slot1_partition: partition@43000 {
			label = "image-1";
			reg = <0x00043000 DT_SIZE_K(220)>;
		};

		storage_partition: partition@7a000 {
			label = "storage";
			reg = <0x0007a000 DT_SIZE_K(24)>;
		};
	};
};

and the .dtsi file is just

&pinctrl {
};

Neither have an "soc" section or anything even remotely similar. Do I need to make one myself? If yes, what is the bare minimum so I'm not enabling things I don't want/need (code size and power savings are CRITICAL in my project)?

This is one (of many) cases where the theory all make sense, but when it comes to putting it into practice everything is clear as mud.
