<p class="MsoNormal"><span style="color:#1F497D">Garbage usually means baud rate. Did you try 115200baud?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">If you are still getting garbage I would recommend seeing it on the scope and making sure voltage levels are fine. The output by default would be TTL level and may need to be converted.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I have used some TTL (1.8V if I remember correctly (TTL-232RG) to convert the signal so I could read the output.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-IN">Hi Team<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">I have a customized board based on Intel valley island design. Reference design uses Intel Baytrail processor E3825, while my design is using E3845.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">I am customizing coreboot for this E3845, but getting just garbage on coreboot, so not able to debug where it is stuck.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">When I add memory test as secondary payload, I cd see some operations happening on console but not able to decode it.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">Tried with all possible baud rates, but no success. USB and display also not enumerating.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">Can you please give some clue? Is it due to different core speed for E3835(1.33GHZ) vs E3845(1.91GHz).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">Where is the option to change this in coreboot?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN">Appreciate your support.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-IN"><o:p> </o:p></span></p>
