Release Notes of the QNX 6.4.0 BSP for IBM PowerPC 970FX Evaluation Board Trunk#System requirements#Target system
Host development system
System Layout#The tables below depict the memory layout for the image and for the flash.
Getting Started#Starting Neutrino#Step 1: Build the BSP 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:
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=10.42.97.136 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 10.42.97.136 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.
