10.5.4 Get Control State (SPI Boot Flash Selection, Boot Order Selection)
This command is used to read out the SPI boot flash and boot order settings.
10.6 Sensors Implemented on the AM4024(E)
The MMC includes several sensors for voltage or temperature monitoring and various others for pass/
fail type signal monitoring. Every sensor is associated with a Sensor Data Record (SDR). Sensor Data
Records contain information about the sensors identification such as sensor type, sensor name, sensor
unit. SDRs also contain the configuration of a specific sensor such as threshold, hysteresis or event
generation capabilities that specify sensor's behavior. Some fields of the sensor SDR are configurable
using IPMI commands others are always set to built-in default values.
Finally, one field, which is the sensor owner, must reflect the module addresses that allow the AMC car-
rier to identify the owner of the sensor when it is scanned and merged into the AMC Carrier's SDR re-
pository.
From the IPMI perspective, the MMC is set up as a satellite management controller (SMC). The MMC sup-
ports sensor devices IPMI commands and uses the static sensor population feature of IPMI. All Sensor
Data Records can be queried using Device SDR commands.
Each sensor has a name field in its SDR. The sensor name has a prefix, which is automatically adapted,
dependent on the physical position of the module in a carrier or in a μTCA chassis.
The following prefixes are used for all sensors of an AMC module:
