19. Copy the images to the /home/user directory ensuring that they are accessible by the TFTP
server.
$ cp /home/user/ltib/rootfs/boot/uImage /home/user
$ cp /home/user/ltib/rootfs/boot/u-boot.bin /home/user
$ cp /home/user/ltib/rootfs.jffs2 /home/user
20. To be able to use the touch screen the device table file must be altered. By default this file
does not enable the input/eventX device files. You can skip this step and instead create the
device files in runtime. Go to section 5.3 if you would like to do it in runtime. Open the
device_table.txt file (it is assumed that your current directory is /home/user/ltib ).
$ gedit bin/device_table.txt
21. Locate the line starting with “ #/dev/input/event ” and uncomment that line

22. Save the file and then force a recompile of the root file system.
$ ./ltib –p dev -f
23. You are now ready to deploy your Linux system to the target board. Chapter 2 describes a
way of deploying the system using a USB memory stick. Chapter 4 describes the u-boot in
more detail and also presents more booting options.
3.5 Add Additional Packages
A small subset of the packages that are available in LTIB has been selected in the default
configuration. If you would like to add more packages follow these instructions.
1. Run the ltib script with the configure option.
$ cd /home/user/ltib
$ ./ltib --configure
2. The LTIB configuration menu will appear, see Figure 10. Go to the “Package List” option and
hit the Enter key (or click Select button).
3. You will now see a long list of packages. Scroll down to the packages you would like to
include and select those packages.
4. Click the Exit button.
5. Click the Exit button.
6. Select “Yes” when asked to save the configuration.
7. LTIB will now compile the selected package and copy it (application or library) to the root file
system.
Please note that all the available packages have not been tested with the Linux port for the LPC3250
OEM Board. The build might even fail if components are missing.
