• Manufacturer Part Number: bcm91250e
• Description: Pci Evaluation Board For Bcm1250
• Manufacturer: Broadcom Corp.

Product Overview
The BCM91250E is a full-length PCI evaluation board with the
SiByte™ BCM1250 dual processor SOC. The board is designed for
software development and for developing PCI applications which
require high-performance processors. The BCM91250E can be plugged
into a PCI slot in any PC, workstation, or server or can be used as a stand-
alone device.
The BCM91250E comes with 256 MB of DDR SDRAM soldered down,
t w o G i g a b i t E t h e r n e t p o r t s f o r n e t w o r k c o n n e c t i v i t y , 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 more information on the BCM1250, refer to the BCM1250 product
brief.
Firmware
The BCM91250E board is provided with the Common Firmware
Environment (CFE), which supports 32-bit and 64-bit operation. The
CFE solution initializes the CPUs and the peripherals on the BCM1250,
including the L2 cache, memory controller, Ethernet MACs, and
UARTs. It also configures the HyperTransport fabric. 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
Two operating systems are provided for the BCM91250E:
• VxWorks
• Linux
Development Tools
Broadcom supports the GNU toolchain. The toolchain is based on
version 3.0 of the compiler, revision 2.11 of binutils and supports cross
compilation from x86/Linux and SPARC/Solaris™ systems.
Broadcom has partnered with Corelis to provide debugging access
through the BCM1250 EJTAG port. There are two EJTAG probe
solutions:
• PICE-BCM1250 is a medium-performance probe that connects to
• •NetICE-BCM1250 is a high-performance probe that connects over
Corelis provides a powerful source-level GUI debugger that works with
both probes. This is adapted for the BCM1250 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 and enable multi-CPU debugging.
SB-1
Core
VxWorks kernel running independently on each core, is an available
option. Developers need to use the Tornado® tools version 2.1 for
64-bit or VxMPTM support. The BSP for BCM91250E in source
form is available initially only from Broadcom.
Full source code is a available from the MIPS-Linux repository
(http://oss.sgi.com/mips/downloads.html), with full support by
