Inventory update for Fru

[Vijay Khemka]

Hi,
I am trying to read FRU information from our system. I don’t see all fields updated in the destination files. Specially I don’t see custom field at all. I debug through code and found that we read eeprom and create object based on config.yaml which has all the information in terms of key-value pair. But I have no clue after this object is sent to dbus and finally printed in output file. I am unable to find source who does this object and write to output file. Any advice here would be appreciated. Also please send me some examples from your own implementations. Below are config and output files and some debug prints.

Config.yaml:

}

I don’t see all field populated and when I debug and found that It takes all field from config and populate everything in object before sending to dbus. Please see below.

Please advise if I am missing anything and location of source who is writing finally to output file and what is driving to restrict number of fields.
