Cannot tree EntityManager dbus service #7

Closed boyercee closed 3 years ago

boyercee commented 3 years ago

I have a working configuration of Entity Manager to detect a board using the FruDevice probe of its EEPROM, so Entity Manager creates the dbus inventory for the exposed FRU fields. I can tree EntityManager dbus service with these versions of openbmc and entity-manager repos,

openbmc SRCREV=708f0cc808588b2b08fcfce91271b2b5e9c9f827 entity-manager SRCREV=98063a4081498ef1840fb58c29e9134183f7d967

However, if I keep the configuration the same, but upgrade to a newer openbmc repo using a later entity-manager revision,

openbmc SRCREV=3f877c75b73e6d18a12f1ce2179b358fe7f92f36 entity-manager SRCREV=c76af0fb1defcc9cc3d000c1ca7592d0f01df2a1

Then a tree of xyz.openbmc_project.EntityManager will either not show the inventory, or it will fail to show any objects. FruDevice is still publishing EEPROM FRU to dbus for Entity Manager to probe.

Not showing inventory objects:

Fails to show any objects:

I realize that there are months of difference between the SRCREVs, and I am tracing the revisions to see what may cause the issue. Please help me determine the cause and the necessary changes to make.

I suspect this was resolved on master a while back with encoding changes. If this is still an issue, feel free to reopen.
