Release Notes of the QNX 6.4.0 BSP for Freescale MPC8349E MDS 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 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. 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: U-Boot 1.1.3 (FSL Development) (Apr 6 2006 - 20:19:16) MPC83XX Clock configuration: Coherent System Bus: 330 MHz Core: 495 MHz Local Bus Controller: 330 MHz Local Bus: 82 MHz DDR: 330 MHz SEC: 110 MHz I2C1: 330 MHz I2C2: 330 MHz TSEC1: 330 MHz TSEC2: 330 MHz USB MPH: 110 MHz USB DR: 110 MHz CPU: MPC8349E, Rev: 11 at 495 MHz Board: Freescale MPC8349ADS I2C: ready DRAM: SDRAM on Local Bus: 64 MB DDR RAM: 256 MB FLASH: 8 MB In: serial Out: serial Err: serial Net: Freescale TSEC0: PHY is Marvell 88E1111 (1410cc2) Freescale TSEC1: PHY is Marvell 88E1111 (1410cc2) Freescale TSEC0, Freescale TSEC1 Hit any key to stop autoboot: 0 => Step 3: Setup the environment 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-8349mds.raw => setenv loadaddr 0x200000 => setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr' => setenv bootdelay 2 => saveenv Saving Environment to Flash...

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

Welcome to QNX Neutrino trunk on the Freescale MPC8349E-QS board
Step 4B: Using the QNX IPL code download
Note:
This method requires an binary image. You have to modify the buildfile to create this format. Change this: [virtual=ppcbe,raw] to this: [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 MPC8349 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.
Note:
Pressing any other key would tell the IPL to boot OS image from flash. This assumes that the OS image has already been copied into the flash. For more details on how to flash the OS image into the board, refer to the Creating a flash partition section. Copy the OS image from your host to the target using this command:
You should now see the Neutrino welcome message on your terminal screen: Welcome to QNX Neutrino 6.3 on the Freescale MPC8349 MDS board 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.
Creating a flash partition#
WARNING:
Use extreme caution if you attempt to modify the contents on the flash. If critical contents (e.g. the IPL code at the bottom of the memory area) become damaged, QNX Neutrino may no longer boot from the flash. You may be able to repair a flash by reprogramming it using an ICE or a flash programmer. The mkflash script creates a 1MB flash image (in binary format) that you can download to the MPC8349 MDS board. This 1 MB image contains the following:
Note:
Flash partitions#To reformat the flash partition, do the following (for an 8 MB flash part): 1. Enter the following command to start the flash filesystem driver: devf-generic -s0xfe000000,8M 2. To prepare the area for the filesystem partition, use the flashctl utility:
Note:
You can use both the -o and -l options at the same time. In the following example, we will erase the ROM monitor, but we will keep the IPL and OS image.
flashctl -p/dev/fs0 -l7M -ve 3. Format the partition: flashctl -p/dev/fs0p0 -l7M -vf 4. Slay, then restart the driver. These steps initialize the /dev/fs0p0 partition. The 8 MB flash partition is then as follows:
A 7 MB fully initialized filesystem space which you can copy files to. For instance: cp -v files /fs0p0/
An unformated 1 MB flash partition in which you can copy the flash image generated by the mkflash script. For instance:cp -v 1MB-flash-image /dev/fs0p1
Driver Command Summary#The following table summarizes the commands to launch the various drivers.
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. Serial:#
Note:
Please make ensure the -c parameter matches the Coherent System Bus clock frequency. Network:#without encryption: with encryption in software: with encryption in hardware (for MPC8572E):
Note:
The latest sources for devnp-mpc85xx.so and devnp-mpcsec.so are available from the networking project. PCI:#
Note:
This driver must be started after the I2C driver is active. The Freescale MPC8349E MDS CPU boards might come by default configured as a PCI device. This will cause the PCI server to not detect PCI devices connected to the bus. Use the following settings to configure the CPU board as a PCI host:
Leave every other switch at the factory-default positions.
