invalid的问题主要是没有require导致，然后也添加一下check_dependencies
然后我看到你的model.json里面对MyEepromModel这个类是的属性是私有的，理论上是不上树，使用busctl –user tree来查询看不到的，我这边把它改成上树的属性
{
"HelloOpenUBMC": {
"path": "/bmc/kepler/HelloOpenUBMC",
"interfaces": {
"bmc.kepler.OpenUBMC.Community": {
"properties":{
"WelcometoOpenUBMC": {}
}
}
},
"properties": {
"Health": {
"baseType": "U32"
}
}
},
"MyCSRModel": {
"path": "/bmc/demo/MyCSRModel/${id}",
"interfaces": {
"bmc.demo.OpenUBMC.Reading": {
"properties":{
"TemperatureCelsius": {
"usage": [
"CSR"
]
}
}
}
}
},
"MyEepromModel": {
"path": "/bmc/kepler/MyEepromModel/${id}",
"interfaces": {
"bmc.kepler.OpenUBMC.Reading": {
"properties": {
"RefEepromTestChip":
{
"usage": [
"CSR"
],
"baseType": "U8[]",
"refInterface": "bmc.kepler.Chip.BlockIO"
}
}
}
}
}
}
然后我再app.lua里面添加创建这个实例

return rsp
end
return Hello_openUBMC
上树属性需要在mdb_interface的添加以下内容：
json/path/mdb/bmc/kepler/MyEepromModel/MyEepromModel.json
{
"MyEepromModel": {
"path": "/bmc/kepler/MyEepromModel/${id}",
"interfaces": [
"bmc.kepler.OpenUBMC.Reading"
]
}
}
json/intf/mdb/bmc/kepler/OpenUBMC/Reading.json
{
"bmc.kepler.OpenUBMC.Reading": {
"properties": {
"RefEepromTestChip":
{
"usage": [
"CSR"
],
"baseType": "U8[]",
"refInterface": "bmc.kepler.Chip.BlockIO",
"description": "eeprom读写方法"
}
}
}
}
回显信息：
Eeprom这个类的信息是显示在hwproxy这个组件的，可以使用busctl --user tree bmc.kepler.hwproxy查看
