3.Getting Started#

3.1 Building the BSP#

You can build a BSP OS image from the source code or the binary components contained in a BSP package. For instructions about building a BSP OS image, please refer to the chapter Working with a BSP in the Building Embedded Systems manual.

3.2 Connect your Hardware#

Connect the serial cable to the first serial port of the P2020DS board to the first serial port of your host machine. There are 2 serial ports on P2020DS. Use the one which is near the boundary of the board. Usually you should see some Uboot output on the console when you connect cable to the correct port. 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.

The correct terminal settings of the program handling serial connection should be:

baudrate 115200
data 8 bit
parity none
stop 1bit
flow control none

3.3 Setup you environment#

1. Power on your target. You should see the u-boot output on your console. 2. Conenct an ethernet cable to any of the 3 PHY port available on the back side of the board.

4. Boot the IFS image#

You can use TFTP download (the default) or serial download to transfer an OS image to the board, as described below.

4.1 Boot via tftp#

This method requires that you put the raw image generated by BSP (by default at $BSP_ROOT/images/ifs-p2020ds.raw) to a TFTP server. This server must be reachable via board and preferably should be on the same LAN. As soon as u-boot starts, press any key so that u-boot stops and doesnt boot the prebuild linux kernel. Configure u-boot parameters as follows:

=> setenv ipaddr
=> setenv serverip
=> setenv bootfile ifs-p2020ds.raw
=> setenv loadaddr 0x100000
=> setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr'
=> setenv bootdelay 2
=> saveenv

Un-Protected 1 sectors
Erasing Flash...
flash erase done
Erased 1 sectors
Writing to Flash... done
Protected 1 sectors
=> boot

4.1 Boot via serial#

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

[virtual=ppcbe-spe,raw] to this:

[virtual=ppcbe-spe,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-p2020ds.srec /dev/ser1 On a Windows host, you can use Hyperterminal's transfer feature to copy the image as a text file.

## First Load Addr = 0x00100000
## Last  Load Addr = 0x0023955B
## Total Size      = 0x0013955C = 1283420 Bytes
## Start Addr      = 0x00101E38

Type go start_addr

At this point, you should see output similar to this when it finishes downloading:

## Starting application at 0x00100000 ...
Welcome to QNX Neutrino 6.4.1 on the PowerPC P2020DS board

Congratulations! QNX 6.4.1 kernel is running on your system. 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 " Driver Command Summary" section.

5. Writing the IFS image to flash using the boot loader#

6. Creating a flash partition#

devb-umass& (This will exit if it doesn't find any mass storage device, so start this only after plugging in a device)


To start network driver without encryption, run:

io-pkt-v4-hc -dmpc85xx

you should see following output when you run ifconfig

# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
        inet netmask 0xff000000
tsec0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500

        capabilities tx=0
        address: 00:04:9f:00:d8:fe
        media: Ethernet none
tsec1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>

        address: 00:11:8c:84:00:11
        media: Ethernet none

To bring a network interface up, type following command

ifconfig tsec0 up

Here is the IP address assign to your target and 24 is the netmask bits (i.e. The LEDs of the RJ45 ports corresponding to an enabled interface shall glow periodically. This can be used to identify the correct port corresponding to each tsec.


run pci-p2020 to enable PCI functionality on your board. This server supports both PCI and PCI-ex devices. To use a PCI or PCI-express device on P2020DS, the device should be connected to the slot before PCI server is run. To detect whether the connect device is detected successfully or not, run following command line utility

pci -v

This shall output all PCI devices currently detected on your system.


The RTC used in P2020DS board is DS3232. Make sure the i2c driver is up and running before running the RTC utility, as the RTC DS3232 is connected to the second i2c bus.

If the i2c driver is not running, issue the following command

i2c-p2020 -i26 -p0xffe03100 --u1

To run the RTC utility, use the following command:

rtc –v ds3232

This command updates the current time and date from the hardware clock in the board.

To set the hardware clock in the board with the current date and time, use the following command:

rtc –s –v ds3232

NOR Flash#


devf-generic -s 0xE8000000,128M,,,128k,2,1 –r

to run the generic Flash filesystem driver on your board. After running this command, two partitions will get created. Normally the file names are as below: /dev/fs0 which is the default mountpoint for socket 0 and /dev/fs0p0 which has the raw access for socket 0, partition 0.

After these partitions get created, we should erase and format the flash using the flashctl utility.

The commands are as follows:

flashctl –p /dev/fs0 –o 0 –l 127M –ev

This command erases the nor flash starting from an offset of 0 to 127MB. Though the nor flash is 128MB, we erase only 127MB as the last 1MB of flash contains the u-boot image.

After giving the above command, slay the driver using the slay devf-generic command and then restart it again.

The Nor flash is erased now and we can mount the given flash filesystem partition as the filesystem mountpoint /flash using the command below:

flashctl –p /dev/fs0p0 –o 0 –l 127M –f –n /flash

After this command is successfully run, slay the driver and restart it again. This formats the nor flash and mounts it over the filesystem mountpoint /flash.

We can create multiple filesystem partitions based on our requirement.

8. Known Issues#

  1. The P2020DS board has a K9WBG08U1M PCB0 , 4k page size flash device installed. This device is not supported by the p2020 and hence the BSP does not have Flash support. This is a board limitation.
  2. errors while loading the BSP into the IDE. Workaround:
    1. In IDE BSP perspective, open the System Builder Projects view, right click on the system builder project "bsp-freescale-p2020-ds", select "Properties", select "Search Paths" from the left panel, select "System Files" tab at the right panel, change the first path which has "install/PLATFORM/boot/sys" in it, change the PLATFORM variable to "ppcbe". Rebuild the system builder project.
