Hi Santosh,

I'm interested in OpenPower VPD format update.

Ok, that's great!
I'll study this repository.
My initial idea is using this tool (API) to update the MAC, BMC's PartNumber, BMC's SerialNumber and BMC's PrettyName of the VPD data on EEPROM.
Then update the VPD data by filling in the Json file.
The API reads the data in Json and writes to the EEPROM to update the VPD.
The above is my initial idea, I would like to ask you whether this is feasible?
Or do you have any concern for this idea?
Thanks

Which VPD format are you interested in updating? Assuming you are using 
the OpenPower VPD format,
there is a tool being implemented in the series of patches here:
https://gerrit.openbmc-project.xyz/c/openbmc/openpower-vpd-parser/+/30239
That can currently handle OpenPower and IBM format VPD and relies on the 
VPD being represented as
D-Bus objects, but we'd be happy to see that getting extended to just 
doing EEPROM writes.

Implement a tool of flashing EEPROM to update the VPD data

Hello everyone,

I plan to implement a tool of flashing EEPROM to update the VPD data(MAC, BMC's PartNumber, BMC's SerialNumber and BMC's PrettyName) recently.
Then I didn't find a similar tool or module on the existing respository of openbmc.
So can I create a new respository to implement this tool?
Or does anyone have any other better comments or suggestions?
Thanks!
