<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In Coreboot 4.4 (Intel baytrail FSP) early serial output use to work (first line being coreboot version followed by RTC Init)<o:p></o:p></p>
<p class="MsoNormal">In Coreboot 4.5 it seems that serial output only works once the FSP initializes the serial port (first line being romstage_main_continue).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Notes: Setup for spew output, using the debug serial port lines.<o:p></o:p></p>
<p class="MsoNormal">I am looking at what might have caused this but though I’d ask if this was a known issue, possibly already fixed with a patch or if it was an error on my part.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Note sure exactly where to search as I have already reviewed the changes in src/drivers/uart/uart8250io.c<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Regards,<o:p></o:p></p>
