Hi Thibaud,

[quote user="Thibaud"]And about the experimental option of nrfutil device command "x-boot-mode-get/set" can you do any comment ?[/quote]

My apologies but I am a little confused.
What is wrong with this command? Are you expecting to use it to tell the application to reboot in bootloader mode or not?
Could you please share the reference from which you learned of this experimental command? It would be helpful as a starting point for me to look further into it.

Regards,

Hieu

Hi Hieu

[quote userid="9456" url="~/f/nordic-q-a/105870/mcuboot-missing-trait-mcuboot-in-nrfutil/526306"]The protocol that you use to talk with MCUboot is also SMP Protocol. As mentioned, a more full-feature support for it is in the work, but we don't comment about release date on DevZone.[/quote]

Ok, no problem. And about the experimental option of nrfutil device command "x-boot-mode-get/set" can you do any comment ?

[quote userid="9456" url="~/f/nordic-q-a/105870/mcuboot-missing-trait-mcuboot-in-nrfutil/526306"]Do you mean you flash MCUboot using nrfUtil with a debugger? Or could you explain in more details what you did here?[/quote]

I flashed a merged.hex of my app and mcuboot with a debugger and I am using nrfutil to do DFU.For now, I need to start my product in bootloader to be able to do the DFU and I am looking for a way to reset my product and start in boot. I thought I may be able to do it with nrfutil experimental option mentionned aboved but I don't know how to make my app handles the nrfutil commands.

Helo Hieu,

For now I ddin't implemented SMP server in my app.

I just flashed mcuBoot and using nrfUtil with mcuBoot.

Now I am looking for a way to go in bootloader from app via nrfUtil command.

Hello Thibaud,

[quote user="Thibaud"]

Are you talking about the experimental option in nrfutil device command x-boot-mode-get/set ?

nrfutil can work with smpserver ?

[/quote]

No, the feature isn't available right now. However, there will be a new feature to communicate with devices using the SMP Protocol.

I used it long time ago with mcumgr but now I am moving to nrfutil because it is faster in USB and I am looking for a way to starts my update sequence from application . For now I am able to do update with nrfutil but I need to have my product in bootloader.

Firstly I was replying to this post because mcuboot traits was missing in nrfutil device list but since my comment I found that I needed to change VID/PID of my product.

I am a little confused here. Do you communicate with your device using SMP Protocol over USB? What commands are you using?

Hello Thibaud,

Are you looking to use nrfutil with MCUboot or SMP Server?

We are working on a feature to work with MCUboot/MCUmgr/SMP server. Unfortunately, I cannot comment on the timeline for this.

Our apologies for the inconvenience.

Hieu

Hello

One year after the issue is still here. Do you have any update ?

Sorry about that. I was using the experimental command and thought that the options are available on the main command as well.

You could use --override-traits with the experimental command. Here is a full command that I used:

nrfutil device x-execute -o program --args 'firmware[file]=./dfu_application.zip' --device-filter 'serialNumber=1234567890' --override-traits mcuBoot

Please note that this command is experimental, so the available parameters might change in the future.

I could not find any documentation about the --override-traits flag. If I try to use it, I get an error:

# nrfutil device program --firmware app_signed.hex --traits mcuBoot --override-traits mcuBoot

error: unexpected argument '--override-traits' found

Hi mdell,

It seems that custom devices are not officially supported by nRF Util yet. The documentation says:

nRF Util supports Nordic Semiconductor Development Kit (DK)s, prototyping platforms, and dongles.

You could try adding --override-traits mcuBoot to the command and see if it helps?
