回覆: Read smbios2 file failed

Wed Aug 24 19:25:37 AEST 2022

Hi Brandon and Jie,

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.

=== Host-side ===

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

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$  ".
