Hi guys, I am beginner in openbmc
I build openbmc with smbios-mdr repository and I have error:

Read data from flash error - Open MDRV2 table file failure

There isnt file in /var/lib/smbios/smbios2

How I can resolve this problem?
Help me please!!!

You need to somehow deliver smbios data image to BMC. This means, your
BIOS should implementat some logic to transfer this data. 
For BMC side see example here:
https://github.com/openbmc/intel-ipmi-oem/blob/master/src/smbiosmdrv2handler.cpp

Hi Andrei,

What is the format of smbios data to transfer to BMC? Is it the same 
content of "dmidecode --dump-bin" command from Host Linux? or anything 
special in formatting the content to send?

No, it is not same as "dmidecode --dump-bin".

Hi Andrei,

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??

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:

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:  https://github.com/openbmc/smbios-mdr/blob/33c948a473bd273fea0cff82d4c99b70b7784be6/include/smbios_mdrv2.hpp#L114

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.

Hi Thang,
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

Thanks Tim, Mike and Andrei for very useful information. We can make it 
work by adding MDRv2 header.

I am finding some information about the IPMI blobs commands. I can see 
some notes at

https://github.com/openbmc/docs/blob/master/designs/binarystore-via-blobs.md

https://github.com/openbmc/phosphor-ipmi-blobs/blob/master/README.md

But I have not found more description about the IPMI blob commands like 
NetFn, Func, ... that I can send a file from Host to BMC. Do you have 
any information about them?


Thanks,

Thang Q. Nguyen

Hi,

Actually I added an ipmi blob interface to smbios-mdr
 https://github.com/openbmc/smbios-mdr/tree/master/src/smbios-ipmi-blobs
<https://github.com/openbmc/smbios-mdr/tree/master/src/smbios-ipmi-blobs>.
With this interface you can send the smbios tables to BMC either through
LinuxBoot or host. The LinuxBoot code
https://github.com/u-root/u-root/tree/master/cmds/exp/smbios_transfer.
Writing and committing to this blob will generate the MDR header.
