By default MACHINE systems are shipped with a Linux (or proprietary) system
|
|
installed on the CompactFlash card or USB drive.
|
|
|
|
First connect your computer via serial port to the device (you may need to use
|
|
a Cisco serial cable depending on your hardware) with a command such as
|
|
"cu -l cuaU0 -s 115200" (assuming cuaU0 is your serial port device). Now apply
|
|
power to the device and start it.
|
|
|
|
Unless you have removed or changed the Linux installation it will be booted
|
|
automatically. If you are quick you can interrupt booting (while still in
|
|
U-Boot) with ^C.
|
|
|
|
OpenBSD/MACHINE uses serial speed 115200. If this speed is not the default
|
|
on the device, you should adjust it by setting the baudrate U-Boot environment
|
|
variable (you also need to reconnect to the serial port using the new speed):
|
|
|
|
# setenv baudrate 115200
|
|
|
|
There are several ways to load an OpenBSD/MACHINE kernel (or ramdisk),
|
|
over TFTP, from the internal CompactFlash or USB storage.
|
|
|
|
Booting from a CF card or USB:
|
|
|
|
To use the miniroot image you will need another machine to plug the
|
|
SD card in to. Any machine type will do, as long as it supports SD card
|
|
storage devices. Under OpenBSD, it will appear as a ``sd'' device, for
|
|
example sd1.
|
|
|
|
Use the dd(1) utility to copy the miniroot to the hard drive.
|
|
The command would likely be, under OpenBSD:
|
|
|
|
dd if=miniroot{:--:}OSrev.img of=/dev/rsd1c
|
|
|
|
On the EdgeRouter Lite, some USB storage devices are not detected
|
|
immediately after power on:
|
|
|
|
USB: (port 0) scanning bus for devices...
|
|
USB device not responding, giving up (status=0)
|
|
1 USB Devices found
|
|
scanning bus for storage devices...
|
|
No device found. Not initialized?
|
|
|
|
In such cases, manually resetting the usb controller may help:
|
|
|
|
Octeon ubnt_e100# usb reset
|
|
|
|
Now load the ramdisk kernel using either of the following commands depending
|
|
on the medium used. For USB:
|
|
|
|
Octeon ubnt_e100# fatload usb 0 $loadaddr bsd.rd
|
|
|
|
For Compact Flash use:
|
|
|
|
# fatload ide 0:1 ${loadaddr} bsd.rd
|
|
|
|
Booting over the network:
|
|
|
|
For TFTP you will first need to set up a TFTP server as described in
|
|
diskless(8). Assuming tftpd(8) chroots into /tftpboot, copy bsd.rd into that
|
|
directory.
|
|
|
|
Power on your OpenBSD/MACHINE device and from the U-Boot prompt set up
|
|
networking. In this example it is assumed you have a DHCP server in your
|
|
network:
|
|
|
|
# dhcp
|
|
|
|
If you don't have a DHCP server, you need to set the ipaddr U-Boot environment
|
|
variable:
|
|
|
|
# setenv ipaddr <static ip address>
|
|
|
|
Now set the IP address of your TFTP server:
|
|
|
|
# setenv serverip <server ip>
|
|
|
|
The ramdisk kernel needs to be loaded into memory. If you use "0" as the
|
|
address, the default address location will be used by U-Boot:
|
|
|
|
# tftpboot 0 bsd.rd
|
|
Using octeth0 device
|
|
TFTP from server 192.168.178.30; our IP address is 192.168.178.89
|
|
Filename 'bsd.rd'.
|
|
Load address: 0x9f00000

|
Booting the installation kernel
|
|
|
|
Now the kernel can be booted from the default memory location, with no
|
|
arguments provided:
|
|
|
|
# bootoctlinux
