问题描述
在进行《适配一款硬件》（见 适配一款硬件 | 文档中心 | openUBMC ）实验时，执行ipmitool.exe -H ip -I lanplus -p 623 -U TestUser -P OpenUBMC@123 -C 17 sdr可以看到传感器Demo Temperature信息，但执行busctl --user tree bmc.kepler.my_app命令，输出没有MyCSRModel_DemoSensor_01信息。
环境信息
-
操作系统：Ubuntu 24.04
-
软件版本：OpenUBMC2512
-
硬件配置：intel i7/64G
重现步骤
-
进行《适配一款硬件》（见 适配一款硬件 | 文档中心 | openUBMC ）实验，包括增加MDS、CSR配置、编译my_app、vpd代码，在mainifest.yml中集成my_app、vpd软件包，构建qemu固件包。
-
运行qemu固件包仿真，在宿主机上ssh登录qemu openubmc，执行busctl --user tree bmc.kepler.my_app查询对象

尝试过的解决方案
编译my_app组件时尝试了bingo build --stage=rc和bingo build --stage=stable，并在manifest.yml中使用对应编译出的stable/rc包，结果都一样
