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.

[Edvin]

I believe you are still talking about installing and uninstalling the SDKs v2.8.0 and v2.9.0. Did you also remove/uninstall the toolchains? 

[Erlend Isachsen]

Hi.

When uninstalling v2.8.0 and 2.9.0 of I specifically used the following command in VSCode:
"nRF Connect: Uninstall Toolchain"

So should be toolchain. Let me know if I should remove SDK as well.

I also see that I didn't provide the best info in terms of what works and what does not work in my original post, sorry for that. If I try to only build the project it finishes successfully, but if I run "Flash to board" or "Erase and flash to board" it fails during re re-building step.

So you might be able to reproduce the problem by:

1. Copy application_update sample from 1.9.1 SDK and common folder in parent directory.
2. Build for nrf9160dk_nrf9160ns (SDK 1.9.1, Toolchain v2.0.0, nRF Connect for VS Code v2025.4.106)
3. Complete build successfully.
4. Edit something some code to trigger a file change.
5. Run: Erase and flash active image to board.

^^This only fails if it has to build and flash in sequence. In my projects, flashing always triggers re-build which is why it is particularly inconvenient. See full attached build log in VSCode below. I have also attached the .vscode-nrf-connect.json for the configuration used. Please let me know if you need anything else.

Can you please try to click "install new toolchain", and then select the folder icon to select the path to your toolchain:

I note that your .vscode-nrf-connect.json points to "toolchainPath": "c:\\ncs\\toolchains\\v2.0.0"

Try making it point to your v1.9.1 toolchain folder. 

Best regards,

Edvin

Which version of the nRF Connect extension for VSCode are you referring to? In the latest version, if I click "install new toolchain" I don't see any versions below 2.0.0 (probably since the support was removed for toolchain versions <2.0.0 in 2025.04.106). I'm also unable to select 1.9.1 as toolchain when adding a build configuration in this version.

If I downgrade to 2025.1.127, install new toolchain, select 1.9.1, build, edit code and run "Flash active image to board" I get the same error. See attached log and configuration.

The same problem also happens using sdk v2.5.1 and toolchain 2.5.1 if that is easier to debug in the latest version? I can also try a fresh install (of for instance SDK v2.5.3 and toolchain 2.5.3), install both through VSCode and see if the problem is still there?

[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.
