Product Overview BCM91250A evaluation board SiByteBCM1250 dual-processor (System Chip) implemented standard form factor. board uses interfaces BCM1250. provide examples both hardware software designers, configurable interfaces used their modes wherever possible. board comes complete with compliant case power supply. Common off-the-shelf peripherals added, such graphics adapters, keyboards mice, hard disks. addition, board provisions specialized applications including PCMCIA HyperTransport(HT) peripherals. Firmware BCM91250A provided with Common Firmware Environment (CFE), which supports 32-bit 64-bit operation. solution initializes CPUs peripherals BCM1250, including cache, memory controller, Ethernet MACs, UARTs. also configures HyperTransportfabric. provides environment downloading booting Operating System using disk, flash memory, network, host boot device. Operating System Support operating systems provided BCM91250A. VxWorks® version with 64-bit support data. VxMPTM, VxWorks® kernel running independently each core, available option. Users will need Tornado® tools version 64bit VxMPsupport. SWARM board supported Wind River Systems.

Linux® version running 32-bit 64-bit mode with full support. Full source code available. Device drivers provided examples many modes BCM1250 interfaces used. Development Tools Broadcom supports toolchain. toolchain based version compiler, revision 2.11 binutils, supports cross compilation from x86/Linux® SPARC/Solarissystems. Broadcom partnered with Corelis provide debugging access through BCM1250 JTAG port. There JTAG probe solutions: PICE-BCM1250 medium-performance probe that connects parallel port This provided with BCM91250A. NetICE-BCM1250 high-performance probe that connects over Ethernet. This probe directly purchased form Corelis. Corelis provides powerful source-level debugger that works with both probes. This been adapted BCM1250 allows registers internal peripherals examined easily. evaluation copy this debugger Windows® 95/98/NT provided with BCM91250A. Broadcom enhanced debugger (GDB) Corelis JTAG probes enable multi-CPU debugging.
