Chapter 5. Installation and Testing
Special RedBoot Commands
The nanoEngine/commEngine has one or two Intel i82559 Ethernet controllers installed, but these have no associ-
ated serial EEPROM in which to record their Ethernet Station Address (ESA, or MAC address). The BSE firmware
records an ESA for the device it uses, but this information is not available to RedBoot; we cannot share it.
To keep the ESAs for the two ethernet interfaces, two new items of RedBoot configuration data are introduced.
You can list them with the RedBoot command fconfig -l thus:
RedBoot> fconfig -l
Run script at boot: false
Use BOOTP for network configuration: false
Local IP address: 10.16.19.91
Default server IP address: 10.16.19.66
Network hardware address [MAC] for eth0: 0x00:0xB5:0xE0:0xB5:0xE0:0x99
Network hardware address [MAC] for eth1: 0x00:0xB5:0xE0:0xB5:0xE0:0x9A
GDB connection port: 9000
Network debug at boot time: false
RedBoot>
You should set them before running RedBoot or eCos applications with the board connected to a network. The
fconfig command can be used as for any configuration data item; the entire ESA is entered in one line.
Memory Maps
The first level page table is located at physical address 0xc0004000. No second level tables are used.
NOTE: The virtual memory maps in this section use a C and B column to indicate whether or not the region is
cached (C) or buffered (B).
