However, in your case,&nbsp;I suspect some incompatibility issue is happening.<br />It looks like the path of the file was&nbsp;resolved incorrectly; and in nRF Connect SDK v2.7.0, there was some major change in the build system.&nbsp;</p> <p>Could you please retry with toolchain v2.6.1?</p> <p>Hieu</p> <p></p><div style="clear:both;"></div>
