<p class="MsoNormal">Hello.<o:p></o:p></p>
<p class="MsoNormal">This is my first-time using entity-manager for inventory & the ability to create one binary image with different json files for different platform configurations.

<p class="MsoNormal">But, first, I am trying to initialize the eeprom on my development board and have it picked up by FruDevice.

<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo1">I defined the eeprom in my dts file but as 24lc128 so at24 driver didn’t pick it up but that allowed me to use i2ctransfer to initialize the eeprom contents.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo1">I initialized the eeprom contents following the layout in this doc:<br>

<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo2">Can someone who has used entity-manager & FruDevice explain the reading/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?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo2">Is there a recommended method for how to initialize the eeprom in manufacturing?
<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo2">Has someone developed a script or an application which given the important pieces of info(see pdf above) formats the contents of the eeprom?<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo2">In general, does one define the eeprom in the dts as well as in the entity-manager json?<o:p></o:p></li></ol>
