Hi All,
I am new to openbmc. I am started porting openbmc features to new hardware.
So, I want to add support for FRUID EEPROM. FRUID contents should be available as dbus objects. What changes needs to done in the application side.
Please provide the steps or suggestions to follow.

You should probably look at https://github.com/openbmc/entity-manager and
existing systems that leverage it. There is already support for specifying the
location of your EEPROM and interpreting it / exposing as dbus objects.
'FruDevice' is typically involved in the EEPROM parsing and then there is
entity-manager JSON that exposes specific EEPROM fields as the Inventory
object(s).

Hi Patrick,
1. According to your suggestion, I can scan my FRU information via busctl command, but entity-manager did not start and can not be accessed.
The log is as below:

I modified one of the configuration which is in entity-manager/configuration folder, its name is Mt_jade.json, The modification is as below from line 759:

Still occurred the above log.
2. According to meta-quanta's commit, I did not find they modify entity-manager/configuration files. And I tried the method, however I can not display them to "ipmitool fru"

I haven't closely followed what else you're doing here, but this
definitely looks wrong -- I think you meant to do
$ echo "24c64 0x50" > /sys/bus/i2c/devices/i2c-3/new_device
Note the position of the close quote -- as you had it above it's just
writing a long string to stdout instead of sending the device name and
i2c address to the sysfs 'new_device' file.

Hi Zev
That maybe occurred question when I copied the log.
I mainly care that why entity manager did not start and there is no service in /lib/system/systemd.
```
root@sky:/lib/systemd/system# ls xyz.openbmc_project.EntityManager
ls: xyz.openbmc_project.EntityManager: No such file or directory
root@sky:/lib/systemd/system# ls *EntityManager*
ls: *EntityManager*: No such file or directory
root@sky:/lib/systemd/system# systemctl xyz.openbmc_project.EntityManager
Unknown command verb xyz.openbmc_project.EntityManager.
root@sky:/lib/systemd/system#
```
