Read smbios2 file failed

Wed Aug 31 02:22:03 AEST 2022

Hi Thang,

Note that you're able to create just the smbios_transfer go binary and
then run it on the host with `go build` command run from the
smbios_transfer (directory
https://github.com/u-root/u-root/tree/da4f04a4d9dbac7408c8046754eedc10b71a527d/cmds/exp/smbios_transfer).

Hi Chris,

Glad you were able to find the answer! We do not use
`phosphor-ipmi-bt` internally (which brings in btbridge) which is
probably why we weren't seeing this issue.

Cheers,
Brandon

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.

And according to Jie's clue (can send the smbios tables to BMC either through LinuxBoot or host), and then I saw both of you were contributing to the "https://urldefense.com/v3/__https://github.com/u-root/u-root/blob/main/cmds/exp/smbios_transfer/smbios_transfer.go__;!!HSntlCg!TV2b4jzad6O_WAZAI1wboTdRw8KbITIWTzC2fn5GNRJ7DifQr1xCsFKxRrh5vW0XmDcRgtYvjcRTS55JUTxghw$  ". Therefore, I have some questions about this, could you help to answer them?
