Hello.

This is my first-time using entity-manager for inven= tory & the ability to create one binary image with different json files= for different platform configurations. 

 

But, first, I am trying to initialize the eeprom on = my development board and have it picked up by FruDevice. 

  1. I defined the eeprom in my dts file but as 24lc128 so at24 driver did= n’t pick it up but that allowed me to use i2ctransfer to initialize t= he eeprom contents.
  2. I initialized the eeprom contents = following the layout in this doc:
    https://= www.intel.com/content/dam/www/public/us/en/documents/product-briefs/platfor= m-management-fru-document-rev-1-2-feb-2013.pdf
  3. I f= ixed the dts file to define the eeprom using generic “24c128” a= nd now at24 is picking it up and I see:
    ls /sys/bus/i2c/devices/8-0051/
    8-00510    eeprom     name  &n= bsp;    subsystem
    driver     modalias   of_node  &nbs= p; uevent

cat /sys/bus/i2c/devices/8-0051/name

24c128

  1. But I also see this:
    ls /sys/bus/i2c/devices/8-0051/8-00510/
    nvmem      of_node    subsystem&nbs= p; type       uevent
  2. In = the json file for entity manager I have:

        {<= o:p>

       &nb= sp;    "Address": "0x51",

       &nb= sp;    "Bus": 8,

       &nb= sp;    "Name": "CN FRU EEPROM",

       &nb= sp;    "Type": "EEPROM"

        },=

  1. But, FruDevice fails looking for "/etc/fru/baseboard.fru.bin&quo= t;.  

Questions:

  1. Can someone who has used entity-manager & FruDevice explain the r= eading/processing of the contents of the eeprom & the of "/etc/fru= /baseboard.fru.bin” or in other words, what am I doing wrong that FruDevice won’t get off the ground?
    2. =
  2. Is there a recommended method for how to initialize the eeprom in man= ufacturing?
  3. Has someone developed a script or an application whic= h given the important pieces of info(see pdf above) formats the contents of= the eeprom?
  4. In general, does one define the eeprom in= the dts as well as in the entity-manager json?

 

Thanks,
Usha
