1. Outline
This manual describes the BSP (Board Support Package) for executing Wind River Linux (hereinafter referred to
as WRLinux) on the Adbc7520 COM Express CPU board based on Freescale QorIQ (P1021) processor.
The BSP is necessary to execute WRLinux on the Adbc7520 and acts as the interface to hardware among the
WRLinux components.
This BSP includes, in addition to WRLinux kernel image, device tree and root file system, layers and other
components necessary to create projects for Adbc7520 on a development environment “Wind River Workbench”.
It is possible to structure WRLinux to make it suitable for Adbc7520 by preparing both this BSP and development
environment provided by WindRiver.
The BSP does not include the development environment. In order to carry out development using the BSP, you
need to purchase the Workbench for WRLinux from Wind River. Please note that this BSP is compliant with GPL,
and may be redistributed freely.
This BSP supports WRLinux4.3 and SMP.
This manual describes an example of using Ubuntu 10.4 on a host Linux system.

2. Installing the BSP
This chapter describes how to install the BSP into the host Linux system.
The BSP is designed on the condition of being used in the Workbench, the development environment for
WRLinux running on Linux.
When using the Workbench, the layer (src/adbc7520.tar.bz2) on the accompanying CD is only used.
Copy the layer file to any directory on a PC with the Workbench installed. 1.
Ex) $ mkdir ~/WindRiver/advanet/layer
$ cp " mount destination of the accompanying CD "/src/adbc7520.tar.bz2
~/WindRiver/advanet/layer
Decompress the copied adbc7520.tar.bz2. 2.
Ex) $ tar jxvf adbc7520.tar.bz2
Now the installation has been completed.

3.2. Preparing boot file
The eMMC Flash memory of the Adbc7520 has U-Boot in it. WRLinux boots up by loading WRLinux kernel
image and device tree using the U-Boot commands.
<<Note>>
Set SW1 to OFF to start the U-Boot from the eMMC Flash memory.
3.3. Connecting console
The RS-232C serial console is used as a console in the WRLinux of the BSP. Connect the COM0 serial port of
the Adbc7520 and a PC in which character terminal (dumb terminal) or terminal software such as hyper terminal
operates with a RS-232C cross cable.
Communication conditions of the serial port are as follows:
baud rate : 115200
character length : 8bit
parity bit : nil
stop bit : 1
flow control : nil
3.4. Connecting network
You can boot up WRLinux via a network by connecting a Ethernet hub or router connected to a host computer
and ETHERNET1 of the Adbc7520 with an Ethernet cable.

3.5.1. Setting for booting from SD card
Create a bootable SD card on a host Linux system in the following way.
Set an SD card in the host Linux system, and create a partition table in the SD card using the fdisk 1.
command.
An example is shown below.
o In the following explanations, the SD card inserted in the host Linux system is named /dev/sdb for
convenience. The device name depends on the host Linux environment. Please change it according to
your environment.
1) Execute the fdisk command.
$ sudo fdisk /dev/sdb
2) SD cards on the market are usually formatted with FAT16 or FAT32. Delete the existing partition table.
Command (m for help): d If there are 2 or more partitions, delete them all.
3) Create a partition table.
Command (m for help): n
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4): 1
First cylinder (1-3871, default 1):
Using default value 1
Last cylinder or +size or +size{K,M,G} (1-3871, default 3871):
Using default value 3871
4) Write the partition table settings.
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
Format the partition table created in 1 to EXT3. 2.
$ sudo mkfs.ext3 /dev/sdb1 -L rootfs
Mount the partition table formatted in 2. 3.
$ sudo mount /dev/sdb1 /mnt/tmp/
Change directory to the partition table mounted in 3. 4.
$ cd /mnt/tmp/
Decompress the root file system. 5.
$ sudo tar jxvf ~/adbc7520_prj/export/adbc75xx-standard-glibc_small-dist.tar.bz2
Copy the kernel image. 6.
$ sudo cp ~/adbc7520_prj/build/linux-adbc75xx-standard-build/
arch/powerpc/boot/uImage boot/
Copy the device tree. 7.
$ sudo cp ~/adbc7520_prj/build/linux-adbc75xx-standard-build/
arch/powerpc/boot/adbc7520.dtb boot/
