1 Overview  
The Software Development Kit or SDK is provided to give the end  
users an environment where they can develop their own  
applications and images. This document is intended as a complete,  
step-by-step guide to create the SDK environment on the 2GB CF  
and does not contain instruction on how to create an application  
using SDK. Please note that the SDK is also referred to as  
development environment in this document.  
Please also refer to UM_SDK.pdf (SDK User’s Manual) how to  
setup/use SDK.

The contents of this chapter have been applied to SDK.  
2.1 Patches to kernel  
Before kernel compilation, patches are first applied to the kernel. The  
following sections lists the patches applied to the kernel.  
Note: All patches have already been applied to /usr/src/linuxon  
SDK. The patch files are stored on  
/buildtree/src/kernel/patches.  
2.1.1 BigPhysArea Patch  
Applying this patch allows the user to allocate a large area of contiguous  
memory during boot up time which can be allocated or deallocated by  
the kernel driver that needs it.  
BigPhysArea  
cd /usr/src/linux  
Patch Application:  
patch –p1 < [source]/bigphysarea.diff  
Where:  
[source] – path where the exploded patch is

2.2 Kernel Configuration and Installation  
2.2.1 Kernel Configuration  
After applying the required patches to the kernel, it is time to set the  
kernel configurations.  
Please make sure that the following  
configurations are set before building the kernel.  
Kernel Configurations  
Kernel Features  
ext3file system  
Remarks  
To enable journaling on an IDE device such as a  
CF. A journalized file system is required in order  
to protect the CF’s XIP partition during abrupt  
hardware on/off events.

XCI-SX1 SDK / SDK Technical Manual  
MSDOS  
Required file system support for mass storage  
devices  
SCSI support  
NFS support  
Required support for mass storage devices  
Required support to enable the system to be  
accessed through NFS mount  
Big Physical Area support Used by the camera driver to reserve large  
memory area at boot time  
To apply the following configurations, go to /usr/src/linux and run  
make menuconfig and start going through the options. After all the  
configurations are set, exit from the configuration and make sure to save  
the changes made. The .configfile is now updated and contains the  
new configurations made.  
The pre-configured .config files are stored in the SDK  
/buildtree/src/kernel/normal,fme, with which you can start  
kernel configuration. The normal/.config is used for SDK kernel. Just  
copy .config file to /usr/src/linux then proceed make  
menuconfig.  
2.2.2 Kernel Compilation  
Run make depin order to generate dependency information and cause  
various build magic to occur. Occasionally, cleaning up the sources  
before building from scratch is advisable. Run make cleanto delete all  
previously created object files. To build a compressed and ready to be  
installed kernel image, run make bzImage. This command creates the  
bzImage file in /usr/src/linux/arch/i386/boot/. Lastly, run  
make modules’ to build the various components chosen to be built as  
modules in the previous section.  
2.2.3 Kernel Installation  
If kernel compilation is successful, the built kernel is now ready to be  
installed. Please copy bzImage to directory grub bootloader specify  
(Refer to UM_SDK.pdf document). In the 2GB CF SDK itself, the kernel  
is  
installed  
in /boot  
directory  
(Refer  
to /boot,  
/boot/grub/grub.conf).

XCI-SX1 SDK / SDK Technical Manual  
And finally, run make modules_install to copy all build modules to  
/lib/modules/2.4.18_mvl30-pc_target/ directory. Please copy  
this directory to the target system directory.  
2.3 Environment System Configurations  
The SDK is installed some software and applied some settings.  
2.3.1 Kernel Files  
The target file system needs to be configured due to the kernel updates  
made. To be sure, copy the following files to its proper destination.  
bzImage  
/usr/src/linux/arch/i386/boot  
/boot/k1  
Source:  
Destination:  
2.3.2 GRUB Configurations  
This GRUBconfiguration file in /boot/grub/grub.confshould contain  
settings as shown below:  
-----------------------------------------------------------  
default=0  
timeout=3  
title XCI-SX1 Smart Camera SDK (0.6)  
root (hd0,0)  
kernel /boot/k1 rw root=/dev/hda1 bigphysarea=1280  
-----------------------------------------------------------  
2.3.3 Required Modules  
To load the proper modules during start up, the /etc/modules file  
should be edited to look like the configuration below:

The order of the list is significant. So unless really required, never  
change the order of list.  
2.3.4 Network Configuration  
The network setting should be configured during boot up process. To be  
able to enable IP address acquisition through DHCP service, add the  
following lines below to /etc/init.d/networking:  
Note: It’s not configured by this file on NFS boot, but by the setting on  
128MB CF.

2.3.5 FTP Service  
To enable file transfer from and to the system, edit the  
/etc/inetd.confto enable FTP service every time the system starts  
up. This feature would be very helpful during installations of other files.  
Please see the setting below.

2.3.6 User Accounts and their Capabilities  
By default, only the root user can access the system. During first boot  
up, the root username still has no password. To give a password for the  
<account_name> user, the command below can be executed:  
passwd <account_name>  
11  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
XCI-SX1 SDK / SDK Technical Manual  
The user has to enter the password for the root user twice.  
The system is also required to have at least a single non-root user. The  
adduser command has been used to add another user. This is  
friendlier front end than the useraddcommand, choosing Debian policy  
conformant UID and GID values, creating a home directory with skeletal  
configuration, running a custom script, and other features.  
adduser admin  
where:  
admin– is the new username  
This command automatically asks for the username’s password twice  
and some information. The other information is optional. For this  
system, the password given for the admin user is admin.  
2.4 Driver Installation  
2.4.1 Video for Linux 2  
The Video4Linux (V4L) included in MontaVista version 3.0 Kernel should  
be updated since the camera driver uses Video4Linux 2 (V4L2) module.  
V4L2 can be downloaded from http://www.thedirks.org/v4l2/.  
To update the Video4Linux module, go to the exploded path of the  
/usr/src/videodevX directory and run make. If this command  
outputs an error saying that the kernel has no support for loadable  
modules, go to /usr/src/linux, make sure the support for the  
loadable module is enabled, and save the configuration. Now return to  
the exploded path of the V4L2 module and run makeagain. This should  
proceed with the compilation and then make install can then be  
issued. This command renames the old V4L modules and updates it  
with the new videodevX.oand v4l_compat.omodules. The header  
file /usr/include/linux/videodev.h is overwritten with the new  
one. To test if the installation is successful, run modprobe videodevX  
to insert the module to the kernel. The module should be listed if lsmod  
command is issued.  
To load the V4L2 modules during start up, append the videodevXline  
in /etc/modulesfile.

XCI-SX1 SDK / SDK Technical Manual  
2.4.2 Camera Driver  
The camera driver (smartcam.o) can now be added to the system.  
The camera driver module is installed in  
/lib/modules/2.4.18_mvl30-  
pc_target/kernel/driver/smartcam directory. Before using the  
camera driver, make sure to invoke the following commands first:  
1. mknod /dev/video0 c 81 0  
- creates the special file node used by the camera driver  
2. ln –s /dev/video0 /dev/video  
- this command is optional; it simply creates a symbolic  
link /dev/video0to the /dev/videonode  
To add the camera driver to the kernel, run modprobe smartcam. The  
module should also be listed if lsmodcommand is issued.  
Appending the smartcam entry to the /etc/modules file enables the  
module to be loaded automatically during system start up. Please note  
that videodevXshould be loaded first before the smartcammodule.  
The  
camera  
module  
source  
code  
is  
installed  
in  
/usr/smartcam/src/camera directory. Just make to build  
smartcam.o.  
2.4.3 Flash Driver  
The flash driver (skxflash.o) has been created to provide a storage  
media for CDS, pedestal, and serial number setting where such values  
need to be stored in a non-volatile memory.  
The flash driver has been installed in /lib/modules/2.4.18_mvl30-  
pc_target/kernel/driver/smartcam directory. The flash driver  
uses the /dev/flash0 special file. If initially not created, do the  
following commands to make the said node available:  
1. mknod /dev/flash0 c 81 0  
- creates the special file node used by the flash driver  
2. ln –s /dev/flash0 /dev/flash  
- this command is optional; it simply creates a symlink  
/dev/flash0to the /dev/flashnode  
13

XCI-SX1 SDK / SDK Technical Manual  
Just like the camera driver, running modprobe skxflash inserts the  
module to the kernel. Adding skxflash entry on the /etc/modules  
file will also enable this module to be loaded at system boot up. The  
source code of the flash driver is also installed in  
/usr/smartcam/src/skxflash directory. Just make to build  
skxflash.o.  
2.5 Library Installation  
2.5.1 XFree86  
XFree86 is an open source X11-based desktop infrastructure that  
provides a client/server interface between the display hardware (the  
mouse, keyboard, and video displays) and the desktop environment  
while also providing both the windowing infrastructure and a  
standardized application interface (API). (http://www.xfree86.org/).  
2.5.1.1 XFree86 Installation  
The library version used for this system is version 4.4.0. The following  
steps below describe how to compile and install the XFree86 application.  
1.make World  
- compiles the said application  
2.make install  
- copies the required files to where they needed to be  
Before running startx, do the command below:  
export PATH=$PATH:/usr/X11R6/bin  
To export this path upon system start up, add this path in  
/etc/profiles:  
PATH=$PATH:/usr/local/sbin:/usr/sbin:/sbin:/usr/X11R6  
/bin  
An X11 configuration file is created in /etc/X11/XF86Config.  
However configured XF86Config files are already installed on SDK.  
XF86Config.en is for US keyboard layout, XF86Config.jp is for JP  
keyboard layout.

XCI-SX1 SDK / SDK Technical Manual  
Edit the /etc/ld.so.conffile and make sure the following lines exist  
and run ‘ldconfig’ command afterwards:  
/lib  
/usr/local/lib  
/usr/X11R6/lib  
/usr/src/linux/lib  
Make sure that the /dev/mousenode exists. If the said node does not  
exist, invoke  
mknod /dev/mouse c 13 63  
Running ‘startx’ should be successful. To test if the mouse is  
properly working on X11 environment, run ‘xev’ command.  
Please note that the development environment has no copy of the  
XFree86 source codes since it consumes a large amount of CF space.  
2.5.1.2 XFree86 Locale Support  
X11 is required to have support of locale settings. The following locale  
environments should be added to the system:  
C  
ja  
ja_JP.UTF-8  
ja.SJIS  
en_US.UTF-8  
C.iso88591  
The localedefcommand is required to create the locale environments.  
The syntax for creating the environment is shown below:  
localedef -i [locale] -f [charmap] [alias]  
The table below shows the required values for each locale environment  
to be supported. Please note that the C locale is the default locale  
environment and does not need to be created.  
Locale Requirements

XCI-SX1 SDK / SDK Technical Manual  
Make sure that all the locale requirements are present in  
/usr/share/i18n/locales  
directory  
and  
the charmap  
requirements are in /usr/share/i18n/charmaps directory. The  
created locale environments are created stored in /usr/lib/locale  
directory. Sometimes, this directory still needs to be created.  
One way to verify the support for locale environment is through the  
xterm command. Running the LC_CTYPE=[locale env] exterm  
command on the X11’s terminal should open a new terminal without any  
warnings of the locale environment specified is supported.  
If ja.SJIS environment still fails after creation of the said local  
environment, add the line below to /etc/locale.alias to allow the  
ja.SJISlocale environment support.  
ja.SJIS  
ja.sjis  
2.5.1.3 XFree86 Customized Settings  
The XFree86 settings have been customized so that it will have the  
same environment as the 128MB CF image. Please refer below for the  
altered configurations.  
/etc/X11/XF86Config  
The same configuration files are applied with target CF (128MB)  
system.  
/usr/X11R6/bin/XFree86  
/usr/X11R6/bin/XFree86_smartcam  
The XFree86_smartcamis used on the target CF (128MB) system  
and linked to /usr/X11R6/bin/X.  
/usr/X11R6/lib/fonts, font.org  
/usr/X11R6/bin/locale, locale.org  
The fonts and locale directory is link to ones in the target CF  
(128MB) system.  
The .orgdirectory has full content. You can pick some if you need  
one.  
/usr/X11R6/lib/X11/xinit/xinitrc  
Key repeat rate is set for efficiency of development.

2.5.2 FLTK  
FLTK is a C++ graphical user interface toolkit that provides GUI  
functionality without the bloat and supports 3D graphics. FLTK is  
provided under the terms of the GNU Library Public License, Version 2  
with exceptions that allow for static linking. (http://www.fltk.org/)  
The minimum requirement for the system is version 1.1.4, which is also  
the FLTK version installed in SDK. Make sure that the X11 library is  
already installed before building the FLTK library. To start FLTK  
installation, go to /usr/src/fltk-1.1.4. Listed below are the steps  
taken to install the FLTK library.  
1. ./configure -–enable-shared

libraries enabled  
2. make clean  
- automatically runs configure with the default (no) options  
and then removes all the binary objects.  
3. make  
- compiles the FLTK library  
4. make install  
- copies the required files to where they should be located  
(to /usr/local/lib)  
2.5.3 LibJPEG  
The JPEG library is used for converting raw images generated by the  
camera into jpeg format. This functionality is used by the Web Monitor.  
The JPEG library used is the same library provided by MVL in  
/usr/libdirectory.  
2.6 Service Installation  
2.6.1 Apache Web Server  
To enable the user to develop Web applications, the Apache Web  
version 1.3.31 server with PHP libraries version 4.3.5rc3 is installed on  
the development environment. Apache is a public-domain open source  
HTTP server. (http://httpd.apache.org/) PHP, on the other hand, is a  
widely-used general-purpose scripting language that is especially suited  
for Web development and can be embedded into HTML. (http://php.net/)  
Please refer to steps listed below for the instructions on how to build the  
Apache Web server and the PHP library.  
1. cd /usr/src/apache_1.3.31  
- changes directory to source directory of Apache (/usr/src)  
2. ./configure  
- runs configuration script of Apache  
3. cd /usr/src/php-4.3.5RC3

2.6.2 SNMP  
The role of a Simple Network Management Protocol (SNMP) Service on  
any computer-based product is to provide a means of remote network  
management without having the need to log into the target system.  
Additional system monitoring features such system event notifications,  
and the like, is also made possible by means of an SNMP service.  
On the SmartCam project, the Net-SNMP package (http://net-  
snmp.sourceforge.net/) is used to detect system ColdStart event and  
provide an additional means to determine the product’s network settings.  
The Net-SNMP package is installed in /usr/src directory. The steps  
below show how to install the said service:  
1../configure  
- configures the build options

To start the SNMP service, run the command below:  
snmpd –c /var/etc/snmp/snmpd.conf  
To test if the SNMP service has been successfully started, run the  
command shown below on the remote host.  
snmpwalk -v2c -c public 192.168.63.150 .1.3  
The snmpwalk command is included in the Net-SNMP package. The  
result of this command should indicate the settings of the SDK  
environment.  
2.6.3 Pro-FTPD  
The Pro-FTPD FTP server has been added in /usr/srcdirectory. This  
code has been edited to support 8.3 file naming convention. Please

2.6.4 GKermit  
G-Kermit is a Unix program for transferring files with the Kermit  
protocol. G-Kermit is a product of the Kermit Project at Columbia  
University in New York City. G-Kermit is fast, small, portable, easy to  
use, interoperable, low-maintenance, stable, and reliable. It features text  
and binary file transfer on both 7-bit and 8-bit connections. Files can be  
transferred singly or in groups. Automatic startup configuration is  
available  
via  
the  
GKERMIT  
environment  
variable.  
G-Kermit is used to transfer the Look Up Tablefrom a remote host to  
the camera device through serial or telnet connection. The application’s  
source code in /usr/src has been customized so that the transferred  
data will be written to /tmp/.LUTbin.
