<div dir="ltr">Hello Mayuri,<div><br></div><div>There are two root hub controllers in BYT: USB 3.0 - xHCI and USB 2.0 (legacy one) - EHCI. The trick here is that you could not have them both working at the same time. Either you set one, or another. Why? They are on the different clocking domains. In other words all your USBs will hang out either of USB 3.0 root hub, either of USB 2.0 root hub. You could NOT mix outside USB ports (to have them hanging out from both root hubs mixed).</div><div><br></div><div>I would recommend to you to set USB 2.0 - EHCI one in Coreboot, for the starters, and see if this will help you to bring board up, for the reasons Naveed already mention here. (legacy support for WIN 7 as example).</div><div><br></div><div>In order to help you, I did some googling, and found the following public useful info:</div><div><div style="font-size:12.8px"><a href="https://www.phoronix.com/scan.php?page=news_item&px=Siemens-MC-TCU3-Coreboot" target="_blank">https://www.phoronix.com/scan.<wbr>php?page=news_item&px=Siemens-<wbr>MC-TCU3-Coreboot</a></div><div style="font-size:12.8px"><a href="http://anzwix.com/a/Coreboot/Mainboardsiemensmctcu3AddNewMainboard" target="_blank">http://anzwix.com/a/Coreboot/<wbr>Mainboardsiemensmctcu3AddNewMa<wbr>inboard</a></div></div><div style="font-size:12.8px"><br></div><div style="font-size:12.8px">I have checked in my newest Coreboot tree (4.4-1038-gdd65ef8): support for TCU3 is there, so you should look upon the following directories and files:</div><div style="font-size:12.8px">src/mainboard/siemens/mc_tcu3/</div><div style="font-size:12.8px"><span style="font-size:12.8px">src/mainboard/siemens/mc_tcu3/</span><span style="font-size:12.8px">devicetree.cb</span></div><div style="font-size:12.8px"><span style="font-size:12.8px"><br></span></div><div style="font-size:12.8px"><span style="font-size:12.8px">And you can peek around, to see if you can make something out of it.</span></div><div style="font-size:12.8px"><span style="font-size:12.8px"><br></span></div><div style="font-size:12.8px"><span style="font-size:12.8px">Hope this helps,</span></div><div style="font-size:12.8px"><span style="font-size:12.8px">Zoran</span></div><div class="gmail_extra">_______<br><div class="gmail_quote"><br></div><div class="gmail_quote">On Thu, Aug 4, 2016 at 7:27 AM, Naveed Ghori <span dir="ltr"><<a href="mailto:naveed.ghori@dti.com.au" target="_blank">naveed.ghori@dti.com.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex">
