Watchdog Timer • Software-configurable, two-stage Watchdog with programmable timeout
ranging from 125 ms to 4096 s in 16 steps
• Serves for generating IRQ or hardware reset
System Timer There are several timers implemented in the CPU. For further information
regarding these timers, refer to the CPU reference manual from Freescale.
IPMI
Module Management
Controller • NXP® ARM7 microcontroller with redundant 512 kB firmware flash and
automatic roll-back strategy
• The MMC carries out IPMI commands such as monitoring several on-
board temperature conditions, board voltages and the power supply sta-
tus, and managing hot swap operations.
• The MMC is accessible via a local IPMB (IPMB-L) and one host Key-
board Controller Style Interface (KCS).
• One MMC system EEPROM for FRU data and firmware private data
Hot Swap The AM4140 has full hot swap capability.
Thermal Management CPU and board overtemperature protection is provided by:
• Three onboard temperature sensors for monitoring the board tempera-
ture
• Specially designed heat sink

Bootloader DENX U-Boot (Universal Boot Loader) with Kontron-specific modifications to
support the AM4140 requirements
IPMI Module Management Controller firmware providing the following features:
• The MMC is accessible via IPMB-L and one KCS interface with interrupt
support
• The MMC firmware can be updated in the field through all supported
onboard interfaces using the function “fwum...” of the open-source tool
“ipmitool”. For further information on the ipmitool refer to the
sourceforge.net website.
• Two MMC flash images with automatic roll-back capability in case of an
upgrade firmware failure
• Board supervision and control extensions such as board reset, power
and firmware flash control, etc.
Operating Systems The board is offered with various Board Support Packages including VxWorks
and Linux operating systems. For further information concerning the operating
systems available for the AM4140, please contact Kontron.
