MCUXpresso extension for vscode not work smoothly

linchenji — Mon, 11 May 2026 07:52:40 GMT

As the title shows,after I have successfully installed MCUXpresso extension for vs code, I also setup one project,built&flashed into MCXW72. But I opened VS code next time,MCUXpresso extension often cannot display its item for long time.I have to restart VS code many many times,then the MCUXpresso extension can just work well. Unfortunately other extension for example NRF connect refreshed its item very quickly.Why?Can anyone solve this problem?

Hello @linchenji ,

Thanks for your post.

The issue is very likely related to extension activation performance. MCUXpresso extension performs environment scanning and initialization during startup, which can occasionally be delayed due to workspace size, SDK path access, or toolchain dependencies.
Suggested actions:

1. Use a lightweight workspace (avoid opening full SDK directory)
2. Check extension logs for activation delay

You can access the logs via:
View → Output → select “MCUXpresso for VS Code” or “Extension Host”, and check if there are any abnormal log entries.

3. Update VS Code and MCUXpresso extension to latest version

Hope it helps.

Celeste
