<div class="markdown_content"><p>I have a actual CodeSys project with version V3.5 SP16 Patch 1 32 Bit and as a device "CODESYS Control for Raspberry Pi SL" version 3.5.16.10. After I added a Library and login I get the error messages: <br/> <span>[FATAL ERROR]</span> Unresolved reference: 'F_CPUCOUNTER'<br/> and it is not possible to login.<br/> In the Log of the device I get two error messages:<br/> from the component CM "Failed to resolve F_CPUCOUNTER"<br/> from the CmpApp "Could not link external function F_CPUCOUNTER"</p> <p>I tested several things to find a solution but I haven't any idea who to solve it.<br/> I tested it also in CodeSys simulation and in this mode it is working fine but I didn't know the difference there.</p> <p>Any ideas?</p></div>
