MCUXpresso for VS Code: Built projects flash without errors but don’t run (MIMXRT1160-EVK)

erlend — Fri, 08 Aug 2025 08:49:01 GMT

I’ve been following the Getting Started with MCUXpresso for VS Code guide and I'm working with a MIMXRT1160-EVK.

Using VS Code and the MCUXpresso extension, I can successfully import SDKs (both from the remote archive and via the SDK builder), and build and flash demo projects without any errors. However, when I run a simple example like the LED blinky, the code compiles and flashes successfully, but the LED does not blink.

Strangely, if I do the exact same thing using the MCUXpresso IDE (not VS Code), the LED blinky example works as expected. Even importing a known-working project from the IDE into VS Code works fine, it builds, flashes, and runs correctly.

I’ve tried multiple SDK versions and different examples, but the issue is consistent: builds done from scratch in VS Code seem to flash but not execute properly.

Has anyone else experienced this? Any ideas on what could be going wrong?

Hi @erlend

“Strangely, if I do the exact same thing using the MCUXpresso IDE (not VS Code), the LED blinky example works as expected. ”

You mentioned that it can work.

Did you try to import the local working SDK package？

Hi @erlend

I have tested it.

You are right.

There is bug in our RT1160 VSCODE LEDBLINKY PROJECT.

I have reported it to our VSCODE team.

Thanks for your information.

Okay thanks, I have also tried with the "Hello world" demo, which i had the same problem with.

Hi @erlend

We will fix it on VSCode_25.08.00 version.

Thanks for your understanding.
