Diagnostic Test Module
The Test Module consists of various test routines for the different hardware components
on the board, such as the XScale core, memory, UART, debug Ethernet, PCI, and
microengines, etc. See
Linux Board Support Package
The embedded Linux* kernel must be modified to support IXB2850 boards. The
modified version is referred to as the Linux Support Package (LSP).
The LSP kernel must support the following IXB2850 hardware-specific components:
The following subsections provides an overview of the LSP kernel drivers required for
the above hardware components.
Hardware-Specific Interrupt Support
The LSP kernel provides support for interrupt sources specific to:
The IXP2850 network processor interrupts are described in detail in Intel IXP2800
Network Processor Programmer’s Reference Manual.
IXB2850 baseboard interrupts are managed through a set of internal CPLD registers
accessible through the NP slow port. The interrupt-related CPLD registers support
setting interrupt mask, reading masked and unmasked interrupts, and simulating
interrupts.
IXB2850 board interrupt sources are:
• Intel
• IXB2850 baseboard-specific interrupts
• IXB2850 board reset
• I
• Standard PCI bus
• IXB2850 on-board banked flash memory
• IXP2850 network processor internal UART (serial console)
• Two on-board 16C550 UARTs (debugger console and BMC serial interface)
• On-board CS8900A 10 Mb Ethernet controller (debug interface)
• On-board 82546 Dual Gigabit Ethernet Controller (via PCI - backplane base
• IXP2850 network processor
• IXB2850 baseboard
• 82546 Dual Port Gigabit Ethernet Controller
• 16C550 UARTs
• Media Mezzanine Cards (Quad Gigabit Ethernet Mezzanine Card)
• Board Management Controller (BMC)
• Thermal alarm
• Board installed at PMC site
• Onboard Ethernet PHYs
