Is this due to something in the FreeMaster file or the model itself?<span class="lia-inline-image-display-wrapper lia-image-align-center" image-alt="wa.PNG" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/271093iAA7EA9EE50886BC1/image-size/medium?v=v2&amp;px=400" role="button" title="wa.PNG" alt="wa.PNG" /></span><span class="lia-inline-image-display-wrapper lia-image-align-center" image-alt="int.PNG" style="width: 400px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/271096i0C9A64F65B1A9F8E/image-size/medium?v=v2&amp;px=400" role="button" title="int.PNG" alt="int.PNG" /></span></P><P>Thank you in advance</P><P>Best Regards</P><P>Ahmed</P> Fri, 29 Mar 2024 07:49:05 GMT https://community.nxp.com/t5/FreeMASTER/Waiting-for-the-first-trigger-screen/m-p/1837753#M1683 Ahmed_Abd_El-Hafez 2024-03-29T07:49:05Z https://community.nxp.com/t5/FreeMASTER/Waiting-for-the-first-trigger-screen/m-p/1840236#M1694 <P>Dear Ahmed,</P> <P>at the bottom of the view area, there is an error "Recorder could not be initialized" probably due to communication issue.
