<div dir="ltr">Hi Chris,<div><br></div><div>I think you were able to set it up correctly. Can you check if you can read/write to the flash memory on the BMC 0x98000000? I am also wondering if that address is correct or not. Like if that address is mapped to the BMC's memory. I have hit an issue where the image transferred does not match because the BIOS didn't set that up properly. I am unsure how to set that up.</div><div><br></div><div>Willy Tu</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jul 13, 2022 at 1:15 AM Chris Chen (TPI) <<a href="mailto:Chris.Chen3@flex.com">Chris.Chen3@flex.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p class="MsoNormal"><span style="font-size:12pt;font-family:Arial,sans-serif;color:black">As you know, I have already built the "burn_my_bmc" on my Host (Eagle Stream with Aspeed 2600). I for now tried to use it to do the in-band update of BMC firmware,
the debug messages of the "burn_my_bmc" look good and I also got "bmc-image" and "bmc.sig" file in the "/run/initramfs" and "/tmp" directory respectively via LPC data transfer mechanism on the BMC. However, one thing is strange which is the content of the
"bmcimage" and "bmc.sig" file are all 0xff. I think this should not be the normal case, perhaps I made a mistake. Following are my steps/changes on the Host-side and BMC-side, could you please take a look at it, is there anything wrong? Or do you have any
suggestions for enabling the feature? Thanks. <u></u><u></u></span></p>
