Some of the known errata on the Intel
the IXP425 network processor B0-step processor. For the still-unresolved errata, see
Errata” on page
The internal device ID — specific to the IXP425 network processor — has been updated to reflect
the B0-step device. For specific information about the device ID, see the IIntel
Line of Network Processors and IXC1100 Control Plane Processor Developer’s Manual, Section
3.5.1.1.
The IXP425 B0 stepping and the Intel
Control Plane Processor have redefined pin D25 from “Reserved” to RCOMP. This pin is used to
adjust the drive strength used for the PCI interface. For specific information regarding the RCOMP
pin, see the Intel
Processor Datasheet.
The B0 stepping and the Intel
Plane Processor support 66-MHz PCI operation.
The B0-stepping device has gone through a top-side mark change to reflect the B0 stepping. For
specific information on the package top-side mark, see
The A0 stepping supported memory configurations of 32 Mbyte to 256 Mbyte. The B0-stepping
device and the Intel
Processor support memory configurations from 8 Mbyte to 256 Mbyte. For further information on
the SDRAM memory interface, see the Intel
IXC1100 Control Plane Processor Developer’s Manual.
The IXP425 B0-stepping and IXP422 processors have included capability for Advanced
Encryption Standard (AES). For a summary of the IXP42X product line and IXC1100 control
plane processors features, see
The B0-stepping and the IXP42X product line and IXC1100 control plane processors include
support for data or address coherency operation through the use of the Page Attribute bit.
The B0-stepping and IXP42X product line and IXC1100 control plane processors have added a
BYTE_SWAP_EN bit located in Expansion Bus Configuration Register 1. The bit location is bit 8
and is defined as BYTE_SWAP_EN. This bit sets byte swapping at the Core Gasket.
The B0 stepping and the IXP42X product line and IXC1100 control plane processors include
enhanced support for little-endian mode of operation.
