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:

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#

4.1 Boot via tftp#

=> setenv ipaddr 10.90.74.214
=> setenv serverip 10.90.74.42
=> setenv bootfile ifs-p2020ds.raw
=> setenv loadaddr 0x100000
=> setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr'
=> setenv bootdelay 2
=> saveenv

Erased 1 sectors
Writing to Flash... done

=> boot

4.1 Boot via serial#

[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 IPL and IFS images to flash using the boot loader#

P2020DS supports bank switching in the NOR Flash. i.e. The upper half of the flash can appear as the lower half and vice-versa. The upper half of the NOR flash has the U-Boot image in the last 1MB. Another boot loader image i.e. IPL can be placed in the last 64KB of the lower half of the NOR flash. So both the boot loader images, U-Boot and IPL can simultaneously be placed in the NOR flash.

The IPL image (ipl-p2020ds) which was built is an SREC image. We should convert it to a Binary image using the QNX utility ntoppc-objcopy. Run the following command at the same location where we ran the "make" command to build the IFS image:

ntoppc-objcopy --input-format=srec --output-format=binary install/ppcbe/boot/sys/ipl-p2020ds images/ipl-p2020ds.bin

1.Use tftp to download the images:

2.Use protect to turn off the flash protection:

=> protect off all
Un-Protect Flash Bank # 1

3.Use erase to erase the first 5 MB of the second half of the flash (for IFS image) (from 0xec000000 to 0xec4fffff):

=> erase 0xec000000 0xec4fffff

........................................ done
Erased 40 sectors

Though the IPL image is 64 KB, we erase 128 KB of the flash, because NOR flash can be erased only sector wise and each sector is 128 KB

4.Use erase to erase the last 128 KB of the first half of the flash (for IPL image) (from 0xebfe0000 to 0xebffffff):

=> erase 0xebfe0000 0xebffffff

. done
Erased 1 sectors

5.Use cp.b to program the IPL image and the IFS image to flash:

=> cp.b 0x100000 0xec000000 0x4f5e80
Copy to Flash... 9....8....7....6....5....4....3....2....1....done
=>
=> cp.b 0x600000 0xebff0000 0x10000
Copy to Flash... 9....8....7....6....5....4....3....2....1....done

6. Switch off the target and change the switch setting of SW7(2:3) from 00 to 01. This switch setting, bank switches the NOR flash.

Now the IFS image will be at the start of the flash i.e. at 0xE8000000 and the IPL image will be in the last 64 KB of the flash i.e. at 0xEFFF0000. Now switch on the target. IPL image will start booting from the NOR flash as below:

6. Creating a flash partition#

Follow the description mentioned below for the NOR flash.

7. Driver Command Summary#

USB#

Network#

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 127.0.0.1 netmask 0xff000000
tsec0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        capabilities tx=0
        enabled=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>
        capabilities tx=0
        enabled=0
        address: 00:04:9f:00:d8:ff
        media: Ethernet none
tsec2: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        capabilities tx=0
        enabled=0
        address: 00:11:8c:84:00:11
        media: Ethernet none

To bring a network interface up, type following command

ifconfig tsec0 10.90.74.214/24 up

Here 10.90.74.214 is the IP address assign to your target and 24 is the netmask bits (i.e. 255.255.255.0) 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.

PCI#

pci -v

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

RTC#

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

i2c-mpc8572 -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#

Run

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:
   • 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". Now select "DLLs" tab at the right panel, change the first path which has "install/PLATFORM/lib/dll" in it, change the PLATFORM variable to "ppcbe-spe". Rebuild the system builder project.
3. When using the QNX IPL, the PCI Server doesn't detect devices behind bridge. (PR:72703). The current workaround is to slay and rerun the PCI server.
4. if you are using 6.4.1 SDP with 4.6 IDE then for successful debugging using gdb download gdb update update 5 from http://community.qnx.com/sf/frs/do/viewRelease/projects.toolchain/frs.gdb.gdb_6_8_u5
