Must toolchain version match SDK version?

[Erlend Isachsen]

Hi.

For a while I have had some issues with the toolchain when using the nRF connect SDK in visual studio code on windows 10. I believe it was after installing SDK version 2.8.0 that I saw the problems first, although I'm not entirely sure. When I use certain commands I get errors in toolchain versions other than 2.8.0. For instance, if I try to build and flash an application using SDK version 1.9.1 and toolchain 1.9.1 I get the attached output.

First of all, is there a workaround to get this to work? I'm currently flashing manually with nrfjprog from command line.

Secondly, should I be matching toolchain versions and SDK versions in the first place? What is the intended/recommended way to use SDK and toolchain versions? If I try build my application with SDK version 1.9.1 and toolchain version 2.8.0 the application appears to run as expected, even with some improvements: resulting merged.hex file is smaller and more warnings are caught in the build process.

Hello,

Yes. This is actually a bug. I don't recall the details (but I will dig it up if we can't quickly solve this). Can you please try to install v2.9.0 as well? And if the issue doesn't go away, can you uninstall v2.8.0 (and keep v2.9.0)? Does that change anything?

Best regards,

Edvin

Hi. Thank you for the suggestions, although it didn't seem to change anything.

I tried to install 2.9.0, after which 2.8.0 and 2.9.0 worked but not 1.9.1 as before. Then, I tried to reboot my computer and ended up with the same result. Next, I uninstalled 2.8.0. As before, 2.9.0 worked but not 1.9.1. Restarted by computer again and still the same result. I installed and uninstalled the toolchain versions with the commands in VSCode.

After that, I checked my C:/ncs folder to see that 2.8.0 was still there, and I did not find 2.9.0. So I took the extra step to delete 2.8.0 in my file explorer, uninstall 2.9.0 in VSCode, install 2.9.0 in the toolchain manager and restart my computer. Still the same error as far as I can tell.

On a separate note, I checked my nRF Connect for VS Code extension version (2025.1.127) and found I did not have the april update (which I believe was released today, after my original question?). I see this issue is addressed in this update since it prompts me that support for 1.x.x toolchains is discontinued. It also states "If you are working with the nRF Connect SDK v1.x, select the nRF Connect SDK Toolchain v2.0.0 for your configuration". So I guess the intended strategy is to install toolchain version 2.0.0 and use that for my applications in 1.x.

So I tried this in nRF Connect for VS Code v2025.4.106, but flashing with toolchian verison 2.0.0 does not work either. Without comparing the errors line by line, the error in 2.0.0 appears to be the same as in 1.9.1.

[Erlend Isachsen]

I did another test and reproduced the same error with fresh installation of SDK 2.4.0 and toolchain 2.4.0. All done in VSCode with version 2025.04.186 of the nRF extension:

1. Install SDK 2.4.0.
2. Install toolchain 2.4.0.
3. "Browse samples" -> "2.4.0" -> "HTTP application update sample"
4. Build for nrf9160dk_nrf9160_ns (Build OK, but non-critical python warning/error in configure step).
5. Add one character to the first printk (to force rebuild).
6. Run command "Flash active image to board". - fails

Please see attached log and configuration.

Can you plesae try to generate support logs and upload it here?

Best regards,

Edvin

[Erlend Isachsen]

Sure.

Attached is support logs and new build log for that log. I built this with the nRF Connect Extension 2025.4.186 to keep it the same as my previous post, but the error is there in 2025.5.92 as well.

Hello,

We are still looking into this. 

Can you please test something for me, using the latest version of the VS Code extension:

Make sure that you have downloaded and installed both NCS v2.4.0 and v2.9.0.

Then delete the build folder so that there are no build folders in the application we are testing. Either do it from windows explorer, or in VS Code using "remove build configuration":

Then, create a new build configuration using "add build configuration", and make sure that you set both SDK version and toolchain version to v2.4.0:

(I didn't have 2.4.0 installed, so showing how to do it for v2.4.1)

Click "Generate and build" on the bottom, and let it finish. Please save the build log. 

Then do a minor modification to main.c,  to force a rebuild, and click flash in VS Code. Save the build log.

Then, if it didn't finish successfully, can you please try the following:

Delete the build folder once more, and open a terminal on your computer. Navigate to the application folder and run the following command:

(if you don't have sdk-manager installed, install it using "nrfutil install sdk-manager")

nrfutil sdk-manager toolchain launch --terminal --ncs-version v2.4.0

It should open a new terminal in the same path. In this new terminal, type:

SET ZEPHYR_BASE=C:\nordic\SDKs\ncs\v2.4.0\zephyr

(but replace the path with the path to your v2.4.0\zephyr folder)

And then use this command to build:

west build -b nrf9160dk_nrf9160_ns -d build

Save the build log

Then, again, do a minor modification, and use this command to flash:

west flash -d build

And save the log.

Are any of the flashing attempts successful? If not, can you please upload all the logs? And if the command line build/flash was successful, can you verify that you have the v2.9.0 toolchain installed using the command:

nrfutil sdk-manager toolchain list

Does this list v2.9.0 as well as v2.4.0?

Best regards,

Edvin

Hello Edvin,

Coming from a duplicate ticket here!

I did this with the blinky application.

First re-build from flash returned this:

It works!! I didnt have a device connected so the flashing part failed.

To me it looks like the ZEPHYR_BASE variable was set incorrectly?

Just for reference, when running the toolchain list command, it returns:

Not sure how I can get it working in vscode though unfortunately.

Hope this helps in rolling out a fix for vscode!

Hello Kireran! Thank you for contributing! I assume the first log is coming from VS Code. Would you mind uploading your "Generate Support Information" as well?
