Hi Ryan, could you open a separate case for this? Include the version for nrfutil and nrfutil device , and the log from nrfutil device program --serial-number 483148395 --firmware build.bl654_dvk_2.1.99.1752590280_merged.hex --log-level trace

I can't seem to program an nRF52840. Any idea what I should try?

nrfjprog on the same system works without issue. This proves the hardware is ok.

So far, nrfutil Linux ARM64 is only working for nrf54l15. I cannot get it to work for programming any nrf52 series.

What puzzles me about this is that all parts of the zephyr toolchain and SDK work on ARM64 already for a long time, so there is no external dependency - that I'm aware of - that is blocking this. Nordic has to step up itself to get their own tools working, if they want to retain their developer base.

Hi Blablub,
I don't have an overview if it will be supported yet. You may want to forward your request to our local RSM of your area. So the request has more priority.

RE: nrf Util: when will the Linux Arm64 be released?

blablub — Mon, 23 Jun 2025 06:58:57 GMT

Are you planning to do also official releases for the arm64 build?

RE: nrf Util: when will the Linux Arm64 be released?

charles.g — Wed, 14 May 2025 08:59:57 GMT

Damned, it's quite a partial release, I saw the sdk-manager as program, thought it would work! I'll leave the ticket open then.

RE: nrf Util: when will the Linux Arm64 be released?

Hung Bui — Wed, 14 May 2025 07:27:17 GMT

Hi Charles,
Unfortunately the sdk-manager (toolchain-manager) is not ported to arm64 yet. The main feature supported on arm64 now is swd programming.

RE: nrf Util: when will the Linux Arm64 be released?

charles.g — Tue, 13 May 2025 10:45:38 GMT

Thanks, but trying to set it up as a full dev environment, I'm getting:

nrfutil sdk-manager search or nrfutil sdk-manager toolchain install xxx
Error: Failed to find remote config for platform: aarch64-unknown-linux-gnu

My device uses NRF52832. Now I need to use Raspberry Pi 5 to upgrade it with ble or cli.
1 But the nrfutil (Arm64 version) released now cannot use the dfu function and cannot be upgraded.(can not install nrf5sdk-tools)
2 pip instsall nrfutil because the latest version can only download 5.2.0. There is a problem when using serial upgrade. It may be necessary to downgrade Python2. But we must use Python3.
This is the error message when doing dfu upgrade with nrfutil V5.2.0. And I use python3.11.2.

I would like to ask if there is a good way to do dfu on Raspberry Pi 5?

RE: nrf Util: when will the Linux Arm64 be released?

Hung Bui — Mon, 12 May 2025 13:57:36 GMT

Hi ACyrus,
Unfortunately the legacy library may not be ported to this platform anytime soon. Please give us some more detail on the DFU use case.

blablub — Fri, 09 May 2025 07:09:21 GMT

Thanks for providing the arm64 build. Flashing a firmware on a nrf54l15 works with `west flash`. Tested on Ubuntu 25.04.

ACyrus — Fri, 09 May 2025 07:01:03 GMT

Hi Hung,
The nrfutil for Arm64 is very good, but I found that it doesn't have nrf5sdk-tools, so I can't use the dfu command.

RE: nrf Util: when will the Linux Arm64 be released?

Hung Bui — Thu, 08 May 2025 13:42:10 GMT

Hi all,
I'm happy to let you know you can now download nrfutil for Arm64 here:

We using the raspberry pi5 as our CI/CD process, still looking forward the nrf Util solution for Arm64.

Hope we already have roadmap which include the raspberry pi5

Hi Arun,
There is some activities internally working on this topic since last month. But we still can't give you an exact date. I will get back if I have any roadmap.

Another request for the same as many including me trying to move from an older a mac X86-64 to M Series.
Hung Bui Please share if there is any updates on this. I see there is mentions for arm64 support in https://github.com/NordicPlayground/nrf-docker but not working for arm64 yet as far as I can see.

We’d like to chime in and share our experience using compact Linux/ARM64 systems for programming nRF52, nRF53, and nRF91 targets with Nordic and Segger's proprietary tools in controlled production setups.

However, the lack of a Linux/ARM64 version of the newer nrfutil tool has become a bottleneck for supporting nRF54 and future Nordic platforms. Right now, we’re forced to include x86-64 systems in our production fixtures just to accommodate this tool, adding unnecessary complexity and cost.

An ARM64-compatible version of nrfutil would significantly streamline our production process. We’d really appreciate it if Nordic could prioritize this development to better support modern ARM-based workflows.

Another chime on for this as I want to use arm64 laptop for development and this is the only package that I need not available for the architecture at the moment.

RE: nrf Util: when will the Linux Arm64 be released?

blablub — Sun, 01 Dec 2024 08:07:13 GMT

I started working on a Snapdragon X Elite laptop with Ubuntu 24.10. It's alpha but it works. There is a arm64 version of nrfjprog which can be used to flash nrf54l15. Unfortunately west requires per default the nrfutil to flash on a nrf54l15dk board.

I will contact our local RSM. Hopefully this will be supported soon.

charles.g — Tue, 26 Nov 2024 16:51:03 GMT

Exactly Ben, the installation of the core tools for compiling on Linux ARM64, even including the nrf Command Line tool and debugging works in/from WSL or in a container.

The example Dockerfile Nordic uses for testing is even ready to support it, there are mentions of arm64. If only nrfutil was open source, we could probably give a hand (wait, wasn't it?).

RE: nrf Util: when will the Linux Arm64 be released?

Ben K — Tue, 26 Nov 2024 13:41:56 GMT

Just to give a status report, it is already possible to fully develop and deploy embedded applications on Windows on ARM (in WSL2) with the Zephyr toolchain, with certain caveats:

I need to use west command line to prepare and build the application, nRF Connect SDK vscode extension isn't useful, since its toolchain manager isn't supported.
WSL has support for USB tunneling via an external library, but that uses VirtualBox Windows drivers that aren't compatible with ARM64, therefore flashing and debugging must happen on the Windows side. SEGGER Ozone debugger can be installed on Windows, with the right configuration file it works fine with the binaries and sources in the WSL filesystem.
Not all J-Link probes support ARM64, specifically only those which can be configured for WinUSB operation instead of legacy SEGGER drivers.

Hi Benedek,

The latest info I got from the team was that they are working on it. But I don't know when it's available.

RE: nrf Util: when will the Linux Arm64 be released?

Ben K — Tue, 26 Nov 2024 09:27:37 GMT

This is also a big blocking issue for those of us with Windows on ARM OS. I'm able to use Zephyr's own SDK by using their Linux aarch64 toolchain on WSL2, but the nRF Connect tools are completely unavailable for both Windows and Linux ARM64. I hope this gets proper traction with the emerging popularity of ARM laptops.

RE: nrf Util: when will the Linux Arm64 be released?

Hung Bui — Fri, 01 Nov 2024 09:57:16 GMT

Hi Charles,
Unfortunately the status now is still it's not supported and we don't have the ETA yet.
I would suggest to send your request to our local RSM so that it get more priority in the list.
