Getting Started#

Starting Neutrino#

Step 1: Build the BSP#

You can build a BSP OS image from the source code or the binary components contained in a BSP package. For instructions about building a BSP OS image, please refer to the chapter Working with a BSP in the Building Embedded Systems manual.

Step 2: Connect your hardware #

Connect one end of the serial cable to the first serial port UART0 (J15) of the Cavium CN57xx board and the other end of the serial cable to the first serial port of your host machine (e.g. ser1 on a Neutrino host).
If you have a Neutrino host with a serial mouse, you may have to move the mouse to the second serial port on your host, because some terminal programs require the first serial port.
Connect the Ethernet cable to the upper RJ45 port namely Ethernet MII Port (J1) on the Cavium CN57xx board and plug in the other end of the Ethernet cable to your local network.

On your host machine, start your favorite terminal program with these settings:

Baud: 115200
Bits: 8
Stop bits: 1
Parity: none
Flow control: none

Apply power to the target board. You should see output similar to the following:

U-Boot 1.1.1 (Development build, svnversion: u-boot:36973, exec:36970) (Build time: Sep 17 2008 - 11:21:03)

DRAM: 4096 MB
Flash: 8 MB
Clearing DRAM........ done
BIST check passed.

Bus 0 (CF Card): not available

Step 3: Setup the environment and boot the IFS image#

Use the printenv command to show the current settings for ipaddr, serverip etc. On your target, type the following, filling in the appropriate IP addresses and ifs file:

Load IFS image via tftp#

Octeon ebh5600# setenv 'ipaddr' '192.168.1.86'
Octeon ebh5600# setenv 'serverip' '192.168.1.80'
Octeon ebh5600# setenv 'bootcmd' 'tftpboot 0 ifs-cn5700_be.elf;bootoctelf 0 0'
Octeon ebh5600# setenv 'bootdelay' '3'
Octeon ebh5600# saveenv
Saving Environment to Flash...
Un-Protected 1 sectors

. done
Erased 1 sectors
Writing to Flash... done
Protected 1 sectors
Octeon ebh5600# reset

Load IFS image from CF#

Octeon ebh5600# setenv 'bootcmd' 'fatload ide 0 0 ifs-cn5700_be.elf;bootoctelf 0 0'
Octeon ebh5600# setenv 'bootdelay' '3'
Octeon ebh5600# saveenv
Saving Environment to Flash...
Un-Protected 1 sectors

. done
Erased 1 sectors
Writing to Flash... done
Protected 1 sectors
Octeon ebh5600# reset

Note:
To enable additional CN5700 cores bootoctelf command should be modified.

Enable eight CN5700 cores:

setenv 'bootcmd' 'tftpboot 0 ifs-cn5700_be.elf;bootoctelf 0 0 coremask=0xFF'

or if loads from CF

setenv 'bootcmd' 'fatload ide 0 0 ifs-cn5700_be.elf;bootoctelf 0 0 coremask=0xFF'

The text you entered is not a valid object ID
More Information
Object IDs begin with an object prefix and end with a number. For example, if you enter
artf2345
the application will jump directly to an artifact with the ID artf2345. Some valid object prefixes are:
artf	for an artifact
doc	for a document
page	for a project page
topc	for a discussion topic
wiki	for a wiki page
