Getting Started#

Starting Neutrino#

Step 1: Build the BSP
You can build a BSP OS image from the source code. 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

1.Connect the power cable to J41 and J40.

2.Connect the serial cable to the serial port J35 ( J35: Used by PPC970FX PIBS/EPOS shell) on the PPC970 board to the first serial port of your host machine (e.g. ser1 on a Neutrino host).

Note: 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.

3.Connect an RJ-45 Ethernet cable to ethernet port J15 ( J15: PPC970FX PIBS (10/100Mbps)) on your target.

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

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

Then, apply power to the target. You should see output similar to the following:

Very simple shell for PIBS
type "help" for help
PIBS-970FX $ help
Very simple shell for PIBS can be used to:
1.Execute following commands:
  alias     : assigns an alias to a command
  boardinfo : displays board information
  bootfile  : loads a file and jumps to file's entry point
  chipclk   : sets chip clocking information
  display   : displays memory
  echo      : displays value of the PIBS variable
  help      : displays help information
  ifconfig  : configures/displays network interface info
  mt        : runs memory test
  pci_dump  : displays results of PCI bus enumeration
  pci_dump_header : displays config. regs of a PCI device
  ping      : sends an echo request to a network host
  reset     : resets the board
  route     : manipulates routing tables
  set       : sets/displays value of the PIBS variable
  storefile : stores file in flash
  unalias   : removes command alias
  version   : displays PIBS version string
2.Set and display PIBS variables. PIBS variable values
  are preserved across reboots.  PIBS variables are:
  autoboot, autobootdelay, boot_hid0, boot_hid1,
  boot_hid4, boot_hid5, bootfilename, chipclkcmd,
  dhcp0, dirname, hwdaddr0, ide80wire, ifconfigcmd0,
  img_addr, initide, initrd_name, ipdstaddr0,
  mask_cpc925_excp, openfirmware, opthtlink, routecmd,
  sync_flood, use_p_paddr, userdata. PIBS variables are
  assigned using the set PIBS variables are assigned
  using the set command, and dispayed using echo command.
3.Display command help.  For example: help bootfile

Step 3: Setup the environment

Please refer to the documentation about PIB.

On your target, type the following, filling in the appropriate IP addresses and ifs file:

PIBS-970FX $ set bootfilename=/root/ifs-ppc970.elf
status: writing PIBS variable value to FLASH
IBS-970FX $ set ipdstaddr0=
status: writing PIBS variable value to FLASH

Step 4: Boot the IFS image

You can use TFTP download (the default) to transfer the image from your host to the target:

Once the above setup is complete, you can run the load command at the => prompt to download the image:

=> bootfile eth

At this point you should see the ROM monitor download the boot image, indicated by a series of number signs. You'll also see output similar to this when it completes downloading:

PIBS-970FX $ bootfile eth
status: ready for TFTP binary file transfer
status: requesting file /root/ifs-ppc970.elf
status: from
status: block=03091
status: jumping to addr. 0x000000000000a01c
Welcome to Neutrino Trunk on the PPC970 Evaluation Board Kit

You can now test the OS simply by executing any shell builtin command or any command residing within the OS image (e.g. ls).

Once the initial image is running, you can update the OS image using the network and flash drivers. For sample command lines, please see the "Summary of driver commands" section.
