Chapter 5. Installation and Testing
NOTE: The MMU has been set up to relocate the VRC4372 supported devices mapped at physical addresses
0x8xxxxxxx to virtual addresses 0xCxxxxxxx.
Ethernet Driver
The ethernet driver is in two parts:
A generic ether driver for the Intel i21143 device is located in devs/eth/intel/i21143 . Its package name is
CYGPKG_DEVS_ETH_INTEL_I21143 .
The platform-specific ether driver is devs/eth/mips/vrc4375 . Its package is CYG-
PKG_DEVS_ETH_MIPS_VRC4375 . This tells the generic driver the address in IO memory of the chip, for example,
and other configuration details. The ESA (MAC address) is by default collected from on-board serial EEPROM,
unless configured statically within this package.
Rebuilding RedBoot
These shell variables provide the platform-specific information needed for building RedBoot according to the
procedure described in
Chapter 3 :
export TARGET=vrc4373
export ARCH_DIR=mips
export PLATFORM_DIR=vrc4373
The names of configuration files are listed above with the description of the associated modes.
PowerPC/MPC860T Analogue & Micro PowerPC 860T
Overview
RedBoot uses the SMC1 serial port. The default serial port settings are 38400,8,N,1. Ethernet is also supported
using the RJ-45 connector. Management of onboard flash is also supported.
The following RedBoot configurations are supported:
