VS code extension update broke RTOS viewer

arunkumar_g — Thu, 14 May 2026 21:16:40 GMT

Hello,

Until now we were using vscode tool version 1.9.20 (old), and we were using https://marketplace.visualstudio.com/items?itemName=mcu-debug.rtos-views to view the status of freertos threads (RT1189). After the update the tool no longer works and just shows "RTOS detection did not finish. It will be resumed on the next halt." Any suggestions?

Thanks

Hi,

MCUXpresso for VS Code has own RTOS viewer for a long time. Please check https://mcuxpresso.nxp.com/mcux-vscode/latest//html/RTOS-Details.html

Also, old change, the extension migrated from using Microsoft C/C++ Debug Adapter to own debug adapter based on Cortex-Debug. You have to create a new Debug Configuration that will automatically create one based on our debug adapter (you'll notice "mcuxpresso-debug" as type).

PS. Please be aware that if you are using Segger debug probe, this requires special enablement for RTOS support (see https://mcuxpresso.nxp.com/mcux-vscode/latest//html/Debug-Views.html#enabling-rtos-awareness)

Regards,

Cristian

Thanks,

In fact the message is coming from MCUXpresso RTOS view itself (I incorrectly referred a different plugin).

I have attached the launch.json and custom device script (it is same as MIMXRT1180-EVK.json for Linkserver 26.3.123, but the "connect-script" is "RT1180_reset.scp".

Our app runs in hyperram and uses SDK 2.16. Freertos variables are correctly set.

I can debug an step through our app, but RTOS Details view still shows "RTOS detection did not finish. It will be resumed on the next halt."

Thanks

Ok I got it working, we where compiling with -Og flag in debug and changing that to -O0 made the viewer work. But I guess the tool needs improvement as Og shall be default for standard edit-debug process?.

Unrelated to this, I also see this warning in debug console

"warning: could not convert '<proj path>\Main.cpp' from the host encoding (CP1252) to UTF-32.
This normally should not happen, please file a bug report."

Thanks

Today I found that MCUXpresso RTOS viewer does not work in release mode, and does not show anything.

But https://marketplace.visualstudio.com/items?itemName=mcu-debug.rtos-views

works with -Og and in release modes, but cannot work with current mcuxpresso vscode plugin (gets disabled?). Is there a way to bring that back?
