Hi, Patrick,
Thanks a lot for the replay.
I got an e820 map of this x86 system (with aspeed ast2500) as follows, and chose the host-lpc address as 0xfe410000 (Unused) alongwith --length 0x10000

And ran this app on host:
./burn_my_bmc
--command update \

--sig image-bmc.sig \

I was able to see there was a 32M size of image-bmc had been uploaded under /run/initramfs, but by using hexdump -C, finding this uploaded file was not the correct image data as expected.
Do you have any suggestions?
Thanks,
Connie

The host-side address is a region set aside in the BIOS that gets reserved in the e820 map. The BiOS dev adds it manually for this purpose.

Hi,
The mapper just adds some convenience functions to be able to find things on D-Bus, so if the mapper can't find it, then it isn't on D-Bus.
https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fopenbmc%2Fdocs%2Fblob%2Fmaster%2Farchitecture%2Fsensor-architecture.md&data=02%7C01%7Cjayashree-d%40hcl.com%7Ced51dc89b13a4679193008d838b27bdf%7C189de737c93a4f5a8b686f4ca9941912%7C0%7C0%7C637321686525370820&sdata=XrhSeOpjTsuanS%2Bwnuk%2Bs2IxRT4NeSGe2sqx%2FuMQuUg%3D&reserved=0
talks about how
phosphor-hwmon-readd will put sensor values on D-Bus.? What I don't think it mentions is that it uses a udev rule to start its service when udev sees the hwmon subsystem hotplug.

Yea, they will show up as /xyz/openbmc_project/sensors/<type>/<name> and bmcweb can find that.

That sensors doc I mentioned above has the goal of describing that.

The service file for that is
/lib/systemd/system/xyz.openbmc_project.ObjectMapper.service. Hopefully that is present on your system.

The meta-ibm layer makes extensive use of phosphor-hwmon:

From the system resource (/redfish/v1/Systems/system), you can find the ComputerSystem.Reset action which can be used to initiate resets:
"Actions": {
"#ComputerSystem.Reset": {
"@Redfish.ActionInfo":
"/redfish/v1/Systems/system/ResetActionInfo",
"target":
"/redfish/v1/Systems/system/Actions/ComputerSystem.Reset"
}
},
The allowable values for ResetType are here:
/redfish/v1/Systems/system/ResetActionInfo.

If you mean the event log, it is here:
