<p class="MsoNormal"><span lang="EN-US">Hello Patrick:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We are currently trying to enable the BMC FW update over LPC on our platform (nuvoton BMC), but we encounter a problem with BIOS.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The BIOS engineer has reserved memory region as mmio space, but we couldn't see any data change in this region during run burn_my_bmc.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We have checked the BMC setting(in lpc_nuvoton.c and LDN SHM) but we couldn't identify the root cause of this problem.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is there any settings we lost?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks,<o:p></o:p></span></p>
