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. Set up the board.
Some PCI cards may not operate at a PCI frequency of 66 MHz.If this is the case for your PCI cards,we recommend that you configure the PCI frequency to be 33 MHz instead. For the Freescale CDS MPC8548 CPU card, the following configuration (i.e. PCI frequency of 33 MHz) has been validated. SW1:[1-6],8 ON, SW1:7 OFF. SW2:[2-6] ON, SW2:1,[7-8] OFF. SW3:[1-2],[4-6] ON, SW3:3,[7-8] OFF. SW4:1,[5-8] ON, SW4:[2-4] OFF. Refer to the hardware manual for a complete list of jumper and dip switch settings to use and compile the ROM monitor for the appropriate frequency. Note: To change the PCI frequency for the Freescale MPC8540 ADS board to 66 MHz: 1. Change the jumper settings as described in the hardware manual. 2. Compile the ROM monitor to use a frequency of 66 MHz. 3. Add the -t66000000 option to the startup command line in your buildfile and rebuild your OS image.
3. Connect the other end of the serial cable to the first available 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.
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) (Dec 4 2006 - 13:13:55) CPU: 8548_E, Version: 2.1, (0x80390021) Core: E500, Version: 2.2, (0x80210022) Clock Configuration: CPU: 999 MHz, CCB: 399 MHz, DDR: 199 MHz, LBC: 49 MHz L1: D-cache 32 kB enabled I-cache 32 kB enabled Board: CDS Version 0x13 CPU Board Revision 0.0 (0x0000) PCI1: 64 bit, 33 MHz, async PCI2: disabled I2C: ready DRAM: Initializing SDRAM: 64 MB DDR: 256 MB FLASH: 16 MB L2 cache 512KB: enabled In: serial Out: serial Err: serial Net: eTSEC0: PHY is Marvell 88E1145 (1410cd4) eTSEC1: PHY is Marvell 88E1145 (1410cd4) eTSEC2: PHY is Marvell 88E1145 (1410cd4) eTSEC3: PHY is Marvell 88E1145 (1410cd4) eTSEC0, eTSEC1, eTSEC2, eTSEC3 The IP address of the board is currently set to 10.42.104.42 The MAC address is 00:04:9f:00:aa:ab If they don't match your network environment, please change them in U-Boot and kernel manually. Hit any key to stop autoboot: 0 => setenv ipaddr 192.168.200.2
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-8548cds.raw => setenv loadaddr 0x100000 => setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr' => setenv bootdelay 2 => saveenv Saving Environment to Flash... Un-Protected 4 sectors Erasing Flash... .... done Erased 4 sectors Writing to Flash... 256 KBdone Protected 4 sectors
Step 4: Boot the IFS image
You can use TFTP download (the default) or serial download to transfer the image from your host to the target:
Step 4A: TFTP download
This method requires a raw image, which the buildfile creates by default.
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:
Speed: 100, full duplex Using MOTO ENET0 device TFTP from server 192.168.200.1; our IP address is 192.168.200.2 Filename 'ifs-8548cds.raw' Load address: 0x100000 Loading: ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ################################################################# ########################################################## done done Bytes transferred = 3361576 (334b28 hex) ## Starting application at 0x00100000 ...
Step 4B: Serial download
This method requires an SREC image. You have to modify the buildfile to create this format. Change this:
[virtual=ppcbe,raw]
to this:
[virtual=ppcbe,srec]
Rebuild the image. On your target, type:
=> setenv loads_echo 0 => saveenv => loads
On your host, copy the image to the serial port that's connected to the board. For example, on a Neutrino host:
cp ifs-8548cds.raw /dev/ser1
On a Windows host, you can use Hyperterminal's transfer feature to copy the image as a text file.
Note: The serial line shouldn't already be in use.
At this point, you should see the ROM monitor download the boot image, indicated by a series of dots. You'll also see output similar to this when it finishes downloading:
## First Load Addr = 0x00100000 ## Last Load Addr = 0x0023955B ## Total Size = 0x0013955C = 1283420 Bytes ## Start Addr = 0x00101E38 =>
Note: The start_addr is the startup entry point address. You can find this address from the mkifs utility (you'll need to use the __{{-v}}__ option to get this information from the mkifs utility; the __{{-v}}__ option is not a default option). For example: #mkifs -v -r../install 85x0ads.8548cds.build ifs-8548cds.raw Offset Size Entry Ramoff Target=Host 100000 100 0 --- /usr/qnx640/target/qnx6/ppcbe/boot/sys/raw.boot 100100 100 ---- --- Startup-header 100200 11108 102bb4 --- /tmp/DAA003706 ... In this example, 102bb4 is the address to use.

You can 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.
devf-generic -s0xff000000,16M
2. To prepare the area for the partition.
Caution: Do not erase the last 8M -- it contains the ROM monitor. Use the -l (length) option to avoid these areas. To create a 1 MB partition, enter the following command:
flashctl -p/dev/fs0 -l1M -ve
3. Format the partition:
flashctl -p/dev/fs0p0 -l1M -vf
4. Slay, then restart the driver:
slay devf-generic & devf-generic -s0xff000000,16M &
You should now have a /fs0p0 directory which you can copy files to.
The following table summarizes the commands to launch the various drivers.
