RedBoot supports only serial port 1, which is connected to the upper
of the stacked serial connectors on the board. The default serial
port settings are 38400,8,N,1. FLASH management is also supported.
The following RedBoot configurations are supported:
RedBoot running from RAM, but contained in the
board's flash boot sector.
RedBoot running from RAM with RedBoot in the
flash boot sector.
A device programmer should be used to program a socketed FLASH part
(AMD 29F040). The board as delivered is configured for a 512K
EPROM. To install a FLASH ROM, Jumpers J30, J31 and J36 need to be
changed as described in the board's User Manual.
NOTE: By default the VRC4375 SIMM control registers are not programmed
since the values used must depend on the SIMMs installed. If SIMMs
are to be used, correct values must be placed in these registers
before accessing the SIMM address range.
NOTE: The allocation of address ranges to devices in the PCI IO and
memory spaces is handled by the eCos PCI support library. They do
not correspond to those described in the board User Manual.
NOTE: The MMU has been set up to relocate the VRC4372 supported devices
mapped at physical addresses 0x8xxxxxxx to virtual addresses
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
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.
