RedBoot supports both serial ports, which are available via the stacked serial connectors on the mother board. The topmost port is the default and is considered to be port 0 by RedBoot. The bottommost port is serial port 1. The default serial port settings are 38400,8,N,1.
FLASH management is also supported, but only for the FLASH device in IC7. This arrangement allows for IC8 to retain either the original Fujitsu board firmware, or some application specific contents.
The following RedBoot configurations are supported:
RedBoot can be installed by directly programming the FLASH device in IC7 or by using the Fujitsu provided software to download and install a version into the FLASH device. Complete instructions are provided separately.
The memory map of this platform is fixed by the hardware (cannot be changed by software). The only attributes which can be modified are control over cacheability, as noted below.
Address Cache?

NOTE: The only configuration currently suppored requires a 64MB SDRAM DIMM to be present on the CPU card. No other memory configuration is supported at this time.
These shell variables provide the platform-specific information needed for building RedBoot according to the procedure described in Chapter 3:
export TARGET=frv400 export ARCH_DIR=frv export PLATFORM_DIR=frv400
The names of configuration files are listed above with the description of the associated modes.
