The Common Firmware Environment (CFE) is designed to be easily portable to designs incorporating current
and future Broadcom MIPS64-compatible broadband processors. Supported platforms include Broadcom's
SiByte processor family (BCM1250, BCM1125H, and so forth) 32-bit and 64-bit memory models, and big and
little-endian operation. There are many parameters configurable at build time that may be used to customize
CFE to suit diverse customer requirements.
On the BCM91250A, CFE can load programs (such as S-records, raw binary, or ELF formatted) from bootstrap
devices in a variety of ways, including:
• Via either Ethernet port, from a TFTP server
• Via the serial port (S-records only)
• Via an IDE disk connected to the BCM1250's generic bus
• Via an IDE CD-ROM drive connected to the BCM1250's generic bus
• Via a PCMCIA flash card in the PCMCIA slot
For additional information on CFE, refer to the Common Firmware Environment (CFE) Specification document
