openbmc + ast2500 web display sensors failed (hwmon seems ok)
I am a newbie no matter from openBmc or ast2500.
After a huge amount of try and errors and browse lots of discussions and docs, right now my ast2500 seems could booting successfully with webui-vue through NCSI network.
And already confirm that hwmon interfaces and conf of my desired sensors are working ( tmp464 and ADCs), and busctl also has showed the objects.
Below are related testings for references.

== (Option 1) I found something seems likely related to my problem from https://stackoverflow.com/questions/74652571/bmcweb-sensors-cannot-be-shown-successfully, which mentioned two methods:
(1) phosphor-hwmon + phosphor-inventory-manager ( my case ) (2) dbus-sensors + entity-manager
And the method 1 seems related to configuration folder.
xxxx@Debian-11:~/aspeedTech/openbmc/meta-aspeed-sdk/recipes-phosphor/configuration$ ls
ast2500-yaml-config ast2500-yaml-config.bb
(Option2) Directly copy meta-ibm/meta-romulus/recipes-phorsphor/inventory/ to my layer
Preview of this layer
xxx@Debian-11:~/aspeedTech/openbmc/meta-aspeed-sdk/recipes-phosphor/inventory$ ls
inventory-cleanup inventory-cleanup.bb phosphor-inventory-manager_%.bbappend
--
But after patching into my project separately above options, still the webUI has nothing display on it, wondering what is the next step I could do......
webui-vue display sensors with nothing snapshot
By the way, my source code info are:
(1) my code base if from AspeedTech repository
(2) Layer at meta-aspeed-sdk
(3) setup using 'ast2500-default'
(4) using webui-vue
**(5) current use layer (the sensors folder default not provided by Aspeed, I reference and modified from meta-romulus)

Here are some references I got from openBMC's discord community. Put here for notes and I will try to work on it!
(Ref 1) Mspinler:
If you're using phosphor-hwmon, you'll need to manually create associations so bmcweb can find them. https://github.com/openbmc/docs/blob/master/architecture/sensor-architecture.md#redfish says which ones. phosphor-inventory-manager has a JSON file you can put them in, see https://github.com/openbmc/docs/blob/master/architecture/sensor-architecture.md#redfish. if you look for associations.json files in openbmc/openbmc you'll see examples
(Ref 2) Troy Lee :
You already populate the sensor on d-bus, then you're almost there. https://github.com/openbmc/docs/blob/master/architecture/sensor-architecture.md#redfish
