<p>Hi Bradon,</p>
<p>smbios_transfer in u-root is from linuxboot in which not all
systems have. I just want to evaluate if it can be supported in
other environment like EDKII via inband IPMI (for example SSIF).
However, I can still not be able to send any raw command (might be
missing some things)<br>
</p>
<p>I don't need to have all commands but just 1 or 2 commands like <span style="caret-color: rgb(36, 41, 47); color: rgb(36, 41, 47);

Hi Thang,
Because we use IPMI blob - it's not so easy to list out all the raw
IPMI commands, but it's certainly doable. However, the smbios_transfer
code is the easiest way (and "should" work) to send all the correct
IPMI commands. Are you also facing similar issues?
Thanks,
Brandon

Hi,
Instead of using smbios_transfer in u-root, what is the IPMI raw
command to send blob data to BMC?
Thanks,

We don't see this failure.. I'm guessing we're 100% sure that IPMI is
not an issue here (I think not, since we're able to enumerate the
blobs)? Could you check to see if the open was actually successful and
that it was written with the correct flags?
Could you also ensure you're at the very latest SRCREV of OpenBMC as well?
Thanks,

I think I have added "smbios-ipmi-blob" library and also updated the SRCREV to the latest in the smbios-mdr_git.bbappend file.
So, I added some debug messages in the "phosphor-ipmi-blobs" and the "u-root" repos respectively. I figured out one weird thing that is the BMC-side doesn't receive the "bmcBlobWrite" command, and then Host-side gets failed due to no response. Following are the messages I captured, could you help to have a look at it and give some clues? Thank you.

Hi Chris,
Yes, running the go program you compile and running smbios_transfer
binary as you did, should do what you expect. However, there is a
PACKAGE_CONFIG you will have to append for the ipmi-blob side of
things to work:
Please try building with the following line in your meta layer's
recipes-phosphor/smbios/smbios-mdr_%.bbappend
```
PACKAGECONFIG:append = " smbios-ipmi-blob"
```
Cheers,
Brandon

Therefore, I have some questions about this, could you help to answer them?
I'm assuming that I can build "smbios_transfer" command and execute it on the Host-side (with installed Ubuntu 20.04), am i correct?
In fact, I'm not familiar with u-root and GO language. However, after referring to some websites to install GO and download u-root, I for now have built the cmd out and run it on my Host. Unfortunately, the result looks like failed.

Do you have any suggestions on this error?
ps. I'm sure the IPMI BT interface is workable.
On the BMC-side, I just need to enable smbios-mdr package, correct? or anything else?
Thanks.

主旨: 回覆: Read smbios2 file failed
Hello everyone,
I would like to send the SMBIOS table from Host to BMC by using "smbios-ipmi-blobs" interface. But, after reviewing all your discussions, I still have no idea how to enable the feature. Could you help to share more details with me? for example,
How to generate a raw SMBIOS table with MDRv2 header? (like using "dmidecode --dump-bin" and what else?)
How do start sending SMBIOS binary file at Host-side? (As I know, the FW update mechanism through IPMI blob would need to build a host-tool, named burn-my-bmc, on the Host and then run the tool to start image data transformation. Does the "smbios-ipmi-blobs" with the same method?)
p.s. The OS running on the Host is Ubuntu 20.04.
Thanks.
Regards,
Chris Chen

Did you try to use smbios_entry_point or DMI from host to BMC /var/lib/smbios/smbios2 for parsing?
You can refer this sysfs-firmware-dmi-tables as below:
The firmware provides DMI structures as a packed list of data referenced by a SMBIOS table entry point.
The SMBIOS entry point contains general information, like SMBIOS version, DMI table size, etc.
The structure, content and size of SMBIOS entry point is dependent on SMBIOS version.
The format of SMBIOS entry point and DMI structures can be read in SMBIOS specification.
The dmi/tables provides raw SMBIOS entry point and DMI tables through sysfs as an alternative to utilities reading them from /dev/mem.
The raw SMBIOS entry point and DMI table are presented as binary attributes and are accessible via:
/sys/firmware/dmi/tables/smbios_entry_point
/sys/firmware/dmi/tables/DMI
Best regards,
Tim

Subject: RE: Read smbios2 file failed
We recently did the same thing and got it working. All you have to do is take the RAW smbios records blob in binary form (delivered as noted below in whatever way you choose) and prepend a specific header: <a class="moz-txt-link-freetext" href="https://urldefense.com/v3/__https://apc01.safelinks.protection.outlook.com/?url=https*3A*2F*2Fgithub.com*2Fopenbmc*2Fsmbios-mdr*2Fblob*2F33c948a473bd273fea0cff82d4c99b70b7784be6*2Finclude*2Fsmbios_mdrv2.hpp*23L114&data=04*7C01*7Cchli30*40nuvoton.com*7C81a4bd29e4904bf4d84608d978510b92*7Ca3f24931d4034b4a94f17d83ac638e07*7C0*7C0*7C637673526954552742*7CUnknown*7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjo__;JSUlJSUlJSUlJSUlJSUlJSUlJSU!!HSntlCg!TV2b4jzad6O_WAZAI1wboTdRw8KbITIWTzC2fn5GNRJ7DifQr1xCsFKxRrh5vW0XmDcRgtYvjcRTS56BTyjjfg$">https://urldefense.com/v3/__https://apc01.safelinks.protection.outlook.com/?url=https*3A*2F*2Fgithub.com*2Fopenbmc*2Fsmbios-mdr*2Fblob*2F33c948a473bd273fea0cff82d4c99b70b7784be6*2Finclude*2Fsmbios_mdrv2.hpp*23L114&data=04*7C01*7Cchli30*40nuvoton.com*7C81a4bd29e4904bf4d84608d978510b92*7Ca3f24931d4034b4a94f17d83ac638e07*7C0*7C0*7C637673526954552742*7CUnknown*7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjo__;JSUlJSUlJSUlJSUlJSUlJSUlJSU!!HSntlCg!TV2b4jzad6O_WAZAI1wboTdRw8KbITIWTzC2fn5GNRJ7DifQr1xCsFKxRrh5vW0XmDcRgtYvjcRTS56BTyjjfg$</a> iV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=oQwcozsSoGlgSFwztPFV3FAoPpRZGYoZ7pc0%2BxDi1MA%3D&reserved=0
It is a little bit fragile as it introduces a dependency on the file download logic to write a non-standard header defined in another service that could potentially change.

Subject: Re: Read smbios2 file failed
I don't know what is format of "dmidecode --dump-bin", but if it just
raw dump of smbios then you only need to add mdr header.
See answer for the same question here:

I see output of "dmidecode --dump-bin" follows SMBIOS specification.
As
the data for smbios-mdr does not follow this, do you know about the
document or any information I can reference to prepare data to send
to BMC??
Best Regards,
