https://devzone.nordicsemi.com/f/nordic-q-a/24551/items-with-options-that-differ-in-keil-projectI am seeing this warning flag on almost every files in Keil projects in the nRF51 SDK v10.0.0, be it original unmodified examples or projects that I modified from such examples. Is there a way to fix the project so Keil stop complaining about the filesen-USTelligent Community 13Wed, 23 Aug 2017 09:32:42 GMThttps://devzone.nordicsemi.com/thread/96636?ContentTypeID=1Wed, 23 Aug 2017 09:32:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d5ed065e-8e87-4e46-b856-f358413d9e6cJ&#248;rgen Holmefjord<p>Hi,</p> <p>The project files in the SDK are autogenerated, and this might create a bit different files than what is generated when creating a project inside Keil. If you look at the .uvprojx files in a text editor before and after removing and adding the file in the project, you should be able to see the differense. I&#39;m not aware of any other method of removing this warning, but like you say, it should not be causing any issues in the project.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
