Zephyr compile error after (unknown) update

[jtf]

soc/arm/ambiq/apollo4x/Kconfig.defconfig.apollo4p:13: error: couldn't parse 'default $(dt_node_reg_size_int,$(DT_NODE_SRAM),1,K)': macro expanded to blank string

This issue is most likely related to a recent update, as Mac1 first started experiencing the problem while Mac2 was still functioning normally. However, after restarting Visual Studio Code on Mac2, the same issue appeared. I also noticed that, before the restart, the build configuration edit page was different between Mac1 and Mac2.

The problem also occurs across all of the example projects that I tested.

Additionally, when trying to open the GUI Kconfig interface, I get this message:
Unable to find Kconfig information to display. Please select a Kconfig file first.

Hello,

Thank you for the screenshot. Could you please share the build log as well? You can attach the complete build log using the insert tab.

Are you encountering the same error message when using the latest SDK and toolchain (V2.7.0)?

Kind regards,
Abhijith

Is this the build log you were looking for? For some reason, the error doesn’t appear there.

I am unable to update the toolchain in the production environment and we had to roll back the Nordic extensions to a version from two months ago, disabling updates (which makes everything work).

Hello,

From the shared log, it seems like a clean build with no reported issues. Does the error in your screenshot appear whenever you open VS Code or the nRF Connect extension? To me, it doesn’t seem related to the application itself.

Kind Regards,

The problem seems to be in Kconfig extension. If I update to the latest version, nRF Kconfig GUI does not work anymore

Thank you! I was struggling with the same issue. Reverting to nRF Kconfig v2024.6.20 allowed me to use the Kconfig GUI again.

I'm using the latest VSCode version on a M2 Macbook Air, for anyone curious.

Thank you for sharing this information.

Best Regards,
