Getting Started#

Step 1: Connect your hardware#

• 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.

Step 2: Build the BSP#

Step 3: Transfer the OS image to the target#

Boot OS images by ROM monitor#

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

2. Setting up the environment

• Apply power to the target board. You should see the U-Boot ROM monitor output.
• You can use TFTP download (the default) to transfer an OS image to the board, as described below.

This method requires a raw image, which the buildfile creates by default.

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

=> setenv ipaddr 192.168.200.2
=> setenv serverip 192.168.200.1
=> setenv bootfile ifs-mpc8360mds.raw
=> setenv loadaddr 0x200000
=> setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr'
=> setenv bootdelay 2
=> saveenv

Welcome to QNX Neutrino trunk on the Freescale MPC8360E MDS board
 

Using the QNX IPL code#

• The images directory contains a mkflash script that creates a 32 MB binary flash image that contains the IPL and the OS image. The IPL is stored at flash offset 0x0 and 0x1F000000, so that the board can boot low and high. Th OS-image is stored at at offset 0x1000000. The IPL's default behavior is to scan the flash strarting at flash offset 0x1000000 for an OS image. The flash image can be loaded to the flash using a flash programmer.
• If your MPC8360E MDS board has u-boot installed, then both the IPL and the OS image can be loaded to RAM using tftpboot, then copied to the flash. For example, you could have u-boot stored at the bottom of the flash and the IPL at the top. Here is an example of how to use u-boot to write the IPL and OS image to the flash:

    erase fff00000 ffffffff
    tftpboot 200000 ipl-mpc8360e
    cp.b 200000 fff00000 8000
    erase ff000000 ff1fffff
    tftpboot 200000 ifs-mpc8360emds.raw
    cp.b 200000 ff000000 200000

2. Using IPL

Note: This section assumes that the IPL has already been flashed into the CPU card.

Causion: This method requires an binary image. You have to modify the buildfile to create this format. Change this:

[virtual=ppcbe,raw]

[virtual=ppcbe,binary]  

• After you apply power to the board, the IPL will run and you should see the following message on your host screen:

 
    Welcome to QNX Neutrino on the Freescale MPC8360E MDS board
    Hit 'd' to download a Neutrino image with sendnto
    Press any other key to boot from flash

• Press d to transfer the OS image over the serial link.

• Copy the OS image from your host to the target using this command:

    On a Windows host:

         
            sendnto -b115200 -dCOM1 ifs-mpc8360emds.bin

    On a QNX Neutrino host:

  
            sendnto -b115200 -d/dev/ser1 ifs-mpc8360emds.bin 

    On a Linux host:

  
	    sendnto -b115200 -d/dev/ttyS0 ifs-mpc8360emds.bin 

    You should now see the Neutrino welcome message on your terminal screen: 

 
   Welcome to QNX Neutrino 6.3 on the Freescale MPC8360E MDS board

Step 4: Start working with Neutrino OS#

   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 " Driver Command Summary" section.

Creating a flash partition#

  
      devf-generic -s0xFE000000,32M

  
      flashctl -p/dev/fs0 -o0 -l6M-ve

  
      flashctl -p/dev/fs0p0 -o0 -l6M-vf

  
      slay devf-generic
      devf-generic -s0xFE000000,32M;

Driver Command Summary#

The driver command lines below are specific to the Freescale MPC8360E MDS board. See the online docs for each driver for additional command-line options and other details.

NOTE: Some of these drivers are commented out in the default buildfile. To use the drivers in the target hardware, you'll need to uncomment them in your buildfile, rebuild the image, and load the image into the board.

Some of the drivers are commented out in the default buildfile. To use the drivers in the target hardware, you'll need to uncomment them in your buildfile, rebuild the image, and load the image into the board.

Note: PCI driver must be started after the I2C driver is active.

Known Issues for this BSP#

• The IPL included in this BSP release is compatible only with the MPC8360EA-MDS-PB (board revision Pilot) version of the development platform. It has been tested under the following configurations:

     MPC8360E silicon rev. 2.1
     Board assembly rev. 0.51
     Factory preset switches
     256 MB DDR2 SO-DIMM pugged into U33

• The BSP's src/hardware/devn/ucc_ec directory contains a README file outlining the specific limitations of the network driver.
• You can not use the second network interface. (QNX Ref# 63723)
• All QNX BSPs ship with an images/Makefile whose purpose is to build an image filesystems (ifs) file using drivers built from source. Currently, it's set up to copy buildfiles from within the source directory structure (source/hardware/startup) to the images directory so that it can generate an ifs. This happens automatically when you do a top-level make, but this mechanism doesn't work when you're making an binary BSP. (QNX Ref# 38242)

Workaround: For a binary-only BSP, change these lines in the root Makefile:

all: install links $(if $(wildcard images/*),images) @echo done
