Hi,

Do you see the same with "open existitng sample"?

Hi，

Do you mean that I should open the light_bulb project and compile it like this?

From the result, it can be successfully compiled, but this is equivalent to modifying the source code of the routines in the SDK, right?

Best regards，

Chuck

Yes, that is true.

It is not a fix, just a test to get more information about this error.

Next up is maybe a fix:
Instead of using the "Create a new application", try to manually copy the light_bulb folder to somewhere outside the SDK, and then this new folder using "Open existing project".

[ChuckRui]

However, I copied the light_bulb project without any changes as you said, and then compiled and burned it, and finally succeeded, but the program did not run, why?

[Sigurd Hellesvik]

What do you mean "did not run"?
What are the symptoms?

[ChuckRui]

light_bulb_ero.zip

Built ant flashed both successed，but the attached 52840 module did not respond, and there was no log output via RTT.
Does the configuration of the pm_static_dfu.yml file have any impact?

Best regards，

Chuck
