Niagra 804: Initial Bootup

Basic boot up via PXE

Get an IP address by DHCP

Request an IP address by typing dhcp:

Octeon cust_n804# dhcp
BOOTP broadcast 1
DHCP client bound to address 172.28.1.84
Octeon cust_n804#

Specify a TFTP server

Specify the TFTP server by setting the serverip environment variable:

Octeon cust_n804# setenv server ip 172.28.0.2

Identify the boot image to pull down

TFTP down the boot image file:

Octeon cust_n804# tftp 0 /images/im_niagra804/vmlinux_n804.bin
Using octmgmt0 device
TFTP from server 172.28.0.2; our IP address is 172.28.1.84
Filename '/images/im_niagra804/vmlinux_n804.bin'.

Boot the system

bootoctlinux 0 coremask=f #f = cores 0-3, 3ff = cores 0-9

Booting Debian from SDK created image

Start the USB service

Octeon cust_n804#  usb start

You should be able to see the USB storage devices using usb storage at the uBoot prompt:

Octeon cust_n804# usb storage

Load the kernel image to memory

Octeon cust_n804# fatload usb 0:1 0x20000000 vmlinux.64

The syntax here is:

fatload = load a file from FAT filesystem
usb = device type to be access is a USB storage device
0:1 = device 0, partition 1 - devices start at 0, partitions start at 1

Boot the kernel image

Octeon cust_n804# bootoctlinux 0x20000000 numcores=10 root=/dev/sda2

 mkdir /mnt/sda1
 mkdir /mnt/sda2
 mount /dev/sda1 /mnt/sda1
 mount /dev/sda2 /mnt/sda2
 mount --bind /proc /mnt/sda2/proc
 chroot /mnt/sda2
 ifconfig mgmt0 172.28.1.95 up
 route add default gw 172.28.0.1 mgmt0

</syntaxhighlight>

Setup Networking in BusyBox

Setup the IP networking

  # grab the IP address from the output of dhcp above
  ifconfig mgmt0 172.28.1.84
  route add default gw 172.28.0.1 mgmt0

Setup the resolv.conf file

  # create the following file
  /mnt/sda1 # cat /etc/resolv.conf 
  nameserver 172.28.0.2
  search pxe.boston.co.uk

After this you can use wget to pull files down from the tftp server or the web
