https://community.nxp.com/t5/Layerscape/LS1046-SerDes-Invalid-Protocol-0000/m-p/1433578#M10285 <P>Hi,<BR />I have a custom board which is using the LS1046A processor. For SerDes2, I am not using any Serdes modules (only using SerDes1 modules),<BR /><BR />I entered 0000 into the SRDS_PRTCL_S2 for the RCW word. For some reason, I am getting a invalid protocol for this selection. I have attached the code snippet that doesn't check for this condition (0000) but it looks valid from the LS1046ARM manual. Does anyone have any idea on why this is not in the code? Is it valid?</P><P>&nbsp;</P><P>See photo of code below and the snippet from the reference manual that allows this protocol.</P><P>&nbsp;</P><P>Thanks!</P><P>&nbsp;</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2022-03-24 123442.png" style="width: 559px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/174732i1415376C5F54D491/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot 2022-03-24 123442.png" alt="Screenshot 2022-03-24 123442.png" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">Screenshot 2022-03-24 123442.png</span></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2022-03-24 123900.png" style="width: 811px;"><img src="https://community.nxp.com/t5/image/serverpage/image-id/174733i9E38B132FF481306/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot 2022-03-24 123900.png" alt="Screenshot 2022-03-24 123900.png" /><span class="lia-inline-image-caption" onclick="event.preventDefault();">Screenshot 2022-03-24 123900.png</span></span></P> Thu, 24 Mar 2022 16:39:40 GMT matthej 2022-03-24T16:39:40Z https://community.nxp.com/t5/Layerscape/LS1046-SerDes-Invalid-Protocol-0000/m-p/1433578#M10285 <P>Hi,<BR />I have a custom board which is using the LS1046A processor.
