Specifications of BCM91125E

• Lead Free Status / Rohs Status: Not Compliant

Product Overview
The BCM91125E is a full-length PCI evaluation board with the
SiByte™ BCM1125H MIPS processor SOC. The board is designed for
software development and developing PCI applications, which require
high-performance processors.
The BCM91125E can be plugged into a PCI slot in any PC, workstation
or server, or can be used as a stand-alone device.
The BCM91125E comes with 128 MB of DDR SDRAM soldered down,
two Gigabit Ethernet ports for network connectivity, a HyperTransport
(formerly LDT) connector, and a Mezzanine socket for connection to
daughter cards. Daughter cards can access HyperTransport, GMII, serial
bus, SMBus, generic bus, and GPIO signals from the board by
connecting to the appropriate sockets.
For additional information about the BCM1125H processors, refer to the
BCM112X Product Brief.
Firmware
The BCM91125E board is provided with the Common Firmware
Environment (CFE), which supports 32-bit and 64-bit operation. The
CFE solution initializes the CPU and peripherals on the BCM1125H,
including the L2 cache, memory controller, Ethernet MACs, and
UARTs. It also configures the HyperTransport fabric. The CFE provides
an environment for downloading and booting an operating system using
a disk, flash memory, the network, or the host as its boot device.

Operating System Support
Three operating systems are provided for the BCM91125E:
• VxWorks
• Linux
• NetBSD version running in 32-bit mode. Support is provided by
Development Tools
Broadcom supports the GNU toolchain and cross compilation from x86/
Linux
Broadcom has partnered with Corelis and Greenhills Software to provide
various options for debugging access through the BCM1125H EJTAG
port.
Corelis provides a powerful source-level GUI debugger that works with
both parallel and networked Corelis probes. This is adapted for the
BCM1125H, and allows the registers of the internal peripherals to be
examined easily.
In addition, Broadcom has enhanced the GNU debugger (GDB) to use
the Corelis EJTAG probes.
