AM4120 IPMI Firmware Functional Description

ID 1045-9586, Rev. 1.0 Page 3

An external 64 kB serial EEPROM chip is used for firmware private data and for FRU inventory

storage. Furthermore, an external 4 MB serial SPI flash is used for additional firmware image

storage.

The MMC implements one local Keyboard Controller Style (KCS) interface with interrupt sup-

port for communication with the system side management software and the U-Boot bootloader.

The IPMB-L bus is used for interconnection with the IPMC.

The MMC provides access to various sensors which permit the monitoring of:

• System power voltages: +12V (PWR), +5V, +3.3V, +3.3V (MP)

• Temperatures: board and airflow near AMC edge-connector

• Power Good, LAN links, board reset, IPMB-L state, Health error, IPMI watchdog, Firm-

ware update/rollback, etc.

2. MMC Firmware

2.1 Key Features

The following are key features of the AM4120 MMC firmware:

• Compliant with the related IPMI and PICMG® specifications

• Firmware designed and specially made for AdvancedMC environments (ATCA, µTCA)

• Supports one KCS interface with interrupt support

• Supports the local IPMB (IPMB-L) interface

• Out-of-Band management and monitoring using IPMB-L interface permits access to

sensors regardless of the module’s CPU state

• Sensor thresholds fully configurable

• Sensor names prefixed with AMC module Bay ID (A1…4, B1…4)

• Usable in µTCA slots 1…12. Sensor names for slots 9…12 are prefixed with C1…C4

• Complete IPMI watchdog functionality

• Complete FRU functionality

• Firmware can be updated in the field

• Firmware image management may be done by the open tool “ipmitool” (functions “hpm”

or “fwum”)

• Downloading new firmware image does not break currently running firmware activities

• Manual and automatic firmware image roll-back in case of upgrade failure

• Interoperable with other AMC, ATCA, or IPMI solutions

• U-Boot fail-over control for automatic U-Boot firmware bank switching after having

detected a non-working U-Boot

• OEM commands for U-Boot firmware bank selection

• Graceful shutdown support

• The “Health” LED shows MMC's heartbeat and pulses on KCS interface traffic
