This manual describes the BSP (Board Support Package) for executing Wind River Linux (hereinafter referred to

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 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

This section describes how to create a WRLinux image file required for executing WRLinux on the Adbc7520.

Here is the procedure of creating with Workbench.

Start Workbench. 1.

Click [File]  [New]  [Project…] in the Workbench menu bar. 2.

Select [Wind River Linux]  [Wind River Linux Platform Project], and click the [Next] button. 3.

Core: E500, Version: 5.1, (0x80212051)

CPU0:800 MHz, CPU1:800 MHz,

Out: serial

Err: serial

Net: eTSEC1, eTSEC2, eTSEC3

Hit any key to stop autoboot: 1

With the default settings, WRLinux boots from the SD card in 1 second.

You can change the setting by command prompt after cancelling the autoboot by key input from the serial

console within 1 second from U-Boot start.

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.

convenience. The device name depends on the host Linux environment. Please change it according to

Command (m for help): n

e extended

p primary partition (1-4)

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.

$ 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/
