10 IPMI Firmware
10.1 O ve r v i ew
The AM4024(E) provides an IPMI controller (NXP® ARM7) with 512 kB of internal firmware flash as well
as external firmware flash for firmware upgrade and rollback. The IPMI controller (Module Management
Controller - MMC) carries out IPMI commands such as monitoring several onboard temperature condi-
tions, board voltages and the power supply status, and managing hot swap operations. The MMC is ac-
cessible via one IPMB-L interface, one host Keyboard Controller Style (KCS) interface and up to four
Gigabit Ethernet interfaces (IOL).
The AM4024(E) is fully compliant with the IPMI - Intelligent Platform Management Interface v2.0 and
the PICMG 2.9 R1.0 specifications.
The following are key features of the AM4024(E)'s IPMI firmware:
»
Keyboard Controller Style (KCS) interface
»
IPMB-L interface for out-of-band management and sensor monitoring
»
IPMI over LAN (IOL) and Serial over LAN (SOL) support
»
Sensor Device functionality with configurable thresholds for monitoring board voltages, CPU
state, board reset, etc.
»
FRU Inventory functionality
»
IPMI Watchdog functionality (power-cycle, reset)
»
Board monitoring and control extensions:
»
Graceful shutdown support
»
uEFI BIOS fail-over control: selection of the SPI boot flash (standard/recovery)
»
Field-upgradable IPMI firmware:
»
via the KCS, IPMB-L or IOL interfaces
»
Download of firmware does not break the currently running firmware or payload activities
»
Two flash banks with rollback capability: manual rollback or automatic in case of upgrade
failure
»
E-Keying (AMC ports and clock in accordance with the AMC.0 R2.0 specification)
For general information on the Kontron IPMI Firmware, refer to the IPMI Firmware User Guide.

Initially the default configuration of the IPMI firmware (KCS interface) is:
»
IRQ = 11
If this is the required configuration, no further action is required. If the configuration must be modi-
fied, the kIpmi uEFI Shell command is used to modify the configuration as required, e.g. "kIpmi irq
[0|11]". For information on the kIpmi uEFI Shell command, refer to Chapter 9, uEFI BIOS.
