nrfutil pkg extreemly slow on mac

[Hjalmar]

Hi,

using nrfutil pkg to generate the settings.hex file for the DFU is exceptionally slow on my M2.

I'm using what I believe is the latest version 

nrfutil 7.5.0 (063f665 2023-05-11)
commit-hash: 063f665c8ef5e4d46167077b52d39cf4e66ca24f
commit-date: 2023-05-11
host: aarch64-apple-darwin
build-timestamp: 2023-05-11T07:48:35.836017Z
classification: nrf-external

Is this expected?

Is this the latest version?

Running it on linux it's a couple hundred ms to finish, where on osx it's 15 seconds.

We might have seen this behavior with few other users on Mac. Can you try to test this again in offline mode not connected to the internet. There might be an issue with nrfutil trying to connect to some server or the firewall on your Mac trying to obstruct its access. The 15 seconds sounds like a timeout for such server connection attempts timeout.

Hi, Thanks for the reply.

No, that didn't make any difference. Just doing this:

hjalmarnilsson@Mac-Studio LCA1000 % nrfutil pkg
Usage: pc_nrfutil_legacy_v6.1.7 pkg [OPTIONS] COMMAND [ARGS]...

This set of commands supports Nordic DFU package generation.

Options:
--help Show this message and exit.

Commands:
display Display the contents of a .zip package file.
generate Generate a zip file for performing DFU.

takes 15 sec in the terminal

If I do a ctrl-c it says it's here (very consistantly) if that gives any clues

hjalmarnilsson@Mac-Studio LCA1000 % nrfutil pkg

It gives more info to the the software team. I am reaching out to them to get more insights on this. Will be back to you when I have some additional info.

Hjalmar, Is there any antivirus running on the Mac? It looks like there is nothing in the nrfutil itself that should cause this delay unless something on MacOS is investigating every files and scripts running.

[Hjalmar]

No I don't have anything like that, can I somehow trace anything for you, just let me know!

Since Even if I don't do anything with the program it hangs (typing nrfutil pkg in the terminal)

[Susheel Nuguru]

Which Mac and which OS version is it?

Maybe I can try to replicate it here. 15 seconds of delay sounds like this tool is practically useless. We have not seen this before so need to replicate that first to be able to debug.

Did you try this? If not Can you test again by running it offline without the internet?

[Hjalmar]

Yes, and it made no difference at all.

[Susheel Nuguru]

I overlooked your version. Your version in the initial thread says that you are using nrfutilv7.5.0 but based on the documentation here , there seems to be a new build for nrfutil that is built for MacOsV13 at nrfutilv7.7

Please upgrade your tool latest and test. 

[Hjalmar]

can you please give me a link? I'm using https://www.nordicsemi.com/Products/Development-tools/nRF-Util/Download#infotabs
and select the universal version, or is there an update command?

[Susheel Nuguru]

Yes you need to have nRF Util installed on your system to run these commands (which you have).but if not, you haven't installed it yet, you can download it from the nRF Util product page and follow the installation instructions provided in the nRF Util documentation.

You can upgrade the nRF Util core module and its commands from the command line using the following steps:

To upgrade the nRF Util core module, run the following command:

nrfutil self-upgrade

This command will update the nRF Util core module to the latest version.

To view the commands with available updates, run the following command:

nrfutil list --outdated

This command will list all the commands that have updates available.

To upgrade the commands, run the following command:

nrfutil upgrade

This command will update all the commands to their latest versions.
