Hi,

Sorry for the delay, I have been out of office.

That you have two versions of the nRF Connect SDK should not be an issue, and the Zephyr SDK is the default toolchain in both v2.0.2 and v2.1.2 anyway.

Have you made sure that ZEPHYR_TOOLCHAIN_VARIANT is not set to gnuarmemb, and have you tried reinstalling the SDK?

Best regards,

Marte

Not sure if you noticed. In the support log are references to both version v2.0.2 and v2.1.2, could this be the issue?

Hi,

I have not been able to find an issue in your support log or another reason for why this is failing. Can you make sure that you do not have ZEPHYR_TOOLCHAIN_VARIANT set to gnuarmemb in your environment variables, and then uninstall and reinstall the SDK?

Best regards,

Marte

When I build from commandline (outside vscode) I have the same result.

Hi,

I am not able to reproduce your error on my side, and I cannot find any issues with the overlay file.

Do you see the same error if you build on command line?

Can you generate support information from VS Code and upload it here? To generate it open command palette (ctrl+shift+p) in VS Code and write nRF Connect: generate support information. Select this option, and the information will be generated in the output tab. Copy that and paste it here.

Best regards,

Marte

When I try to generate new build configuration I get the same error.

Hi,

Are you using the same build directory as when you built with gnuarmemb? If so, can you try deleting the build directory and creating a new one?

I see from your log that it is complaining about some devicetree files. Can you share what your nrf52840dk_nrf52840.overlay looks like?

Best regards,

Marte

Thanks for the explanation. Then I don't understand why compile fails when ZEPHYR_TOOLCHAIN_VARIANT is set to zephyr?

RE: toolchain manager sets ZEPHYR_TOOLCHAIN_VARIANT incorrectly

Hi,

1. The correct toolchain variant for v2.1.2 of nRF Connect SDK is zephyr. In v2.0.0 the SDK started using the Zephyr SDK as default toolchain instead of the GNU Arm Embedded Toolchain. Since you did the installation using the Toolchain Manager, then you should have the Zephyr SDK toolchain under /home/ephimee/ncs2/toolchains/v2.1.2/.

2. You can see the source code for the Toolchain Manager here: https://github.com/NordicSemiconductor/pc-nrfconnect-toolchain-manager. I cannot find that the ZEPHYR_TOOLCHAIN_VARIANT is set to zephyr anywhere, nor that ZEPHYR_SDK_INSTALL_DIR is set. However, if no toolchain is selected, then the build system will look for the Zephyr SDK and use this toolchain.

3. VS Code is opened here: https://github.com/NordicSemiconductor/pc-nrfconnect-toolchain-manager/blob/main/src/VsCodeDialog/vscode.ts.

4. No, zephyr is the default toolchain, so this is not a bug.

Best regards,

Marte
