Complete the following steps to get to a BCM91125F CFE (firmware) prompt.
1
Connect a 9-pin null modem cable to the serial port of the BCM91125F and to a serial port on a workstation/PC.
2
Use a terminal program and set it to 115200 bps, 8-bit data, 1-stop bit, no parity, and no flow control.
3
Power up the BCM91125F using one of the methods described in
“Powering Up the Board” on page 6
.
After a short delay, the CFE initialization output and serial console prompt should display. The following is an
example of the output:
CFE version 1.0.40 for BCM91125F (64bit,MP,BE,MIPS)

At the prompt, a program can be run via the network from a TFTP server by doing the following:
a. Connect the BCM91125F Ethernet port E0 with an Ethernet cable to a switch, repeater, or directly to the
Ethernet port of the file server.
b. To initialize Ethernet port E0, type the following:
ifconfig eth0 -auto
c. To run a program, type the following:
boot -elf tftp_server:/path_to_software/program
Note:
Because the Broadcom PHYs handle direct connects automatically, a crossover cable for
direct connects is not needed.
Note:
The ifconfig eth0 -auto command can only be used with a DHCP server.
