memory address. The NAND FLASH from 0x400000 and up is used for Linux root file system.
The U-boot passes the MTD device partition setting to the Linux kernel via the bootargs
environment variable.
Loading Linux Kernel and root File System
The U-boot boot-loader provides many ways to load Linux kernel and file system into FLASH
memory. The loading by Ethernet network is shown here. User can consult U-boot manual for
other methods of loading data.
After power on the GESBC-3130 board, stop the U-boot auto-execution by press any key. The
following message should be shown on the terminal console on the host PC connected to the
GESBC-3130 board.
Version 1.0 Page 14 of 18 20-Jun-11
GESBC-3130 User’s Manual
The net work address and server address must be set before network transfer can take place. The
following commands will set the SBC IP address and server IP address,
set ipaddr xxx.xxx.xxx.xxx
set serverip xxx.xxx.xxx.xxx
The server IP is the IP address where a TFTP server must be run. To load Linux kernel type in the
following command,
t 0x31000000 uImage
The U-boot will load uImage file from the TFTP server whose IP address is specified by the
serverip environment vairbale.
The NAND FLASH sectors must be erased first before new kernel image can be stored. The
following command will erase the NAND FLASH sectors reserved for Linux kernel,
nand erase 0x100000 0x200000
The use the flowing command to store the kernel image from SDRAM to NAND FLASH,
nand write.jffs2 0x31000000 0x100000 0x200000
The following commands can be used to load root file system into the FLASH memory,
nand erase 0x400000 0x7c000000
t 0x30000000 rootfs.img
nand write.jffs2 0x30000000 x0400000 $(filesize)
Please be noted that the image is first loaded into the SDRAM and then stored into the FLASH
memory. The image size can not exceed the available SDRAM on the board.
After the kernel and root file system have been updated the board can be simply reboot by recycle
the power.

Chapter 5 – Development Tools
Overview
This chapter provides a brief introduction to development tools that are available for the LPC-3130
System-on-a-Chip processor. The central processing core on the LPC-3130 is a 180 MHz
ARM926EJ-S processor. The ARM926EJ-S RISC processing core is supported through various
toolsets available from third party suppliers. The typical toolset required for the code development
is a compiler, assembler, linker and a source-level code debugger. Code debugging is supported
via the on-chip JTAG interface.
Linux Development Tool Chain
The Linux development tool chain is available at Glomation website in the support page. A host
PC running Linux operating system is required to run the development tools. This guide assumes
user had basic Linux or Unix application development knowledge.
Host Computer Requirement
The host PC should run Redhead, SuSe, or other Linux distribution, a RS-232 serial port, at least
500MB free disk space, and a terminal program such as minicom.
Hardware Connection
A null modem cable is required to connect GESBC-3130 to the host computer.
Install Linux Development Tool Chain
The ARM Linux Development Tool chain can be installed in any directory on the host system.
The following example uses cross compiler default directory /usr/local/arm as the installing
directory for the ARM Linux cross compiler.
1. Login as root and untar the tool chain
cd /
tar jxvf /<cross compiler tar file directory>/ Generic-arm_gcc-4.2.3glibc-2.3.3.tar.bz2
2. Set up the directory path variable
export PATH=/usr/local/arm/gcc-4.2.3-glibc-2.3.3/arm-unknown-linuxgnu/bin:$PATH
Version 1.0 Page 16 of 18 20-Jun-11
GESBC-3130 User’s Manual
above command can be included in the shell resource file so it is executed every time you
login. For bash shell, a good place to put is in .bashrc in your home directory.
Compile Linux Kernel
The GESBC-3130 is shipped with Linux kernel version 2.6.33.14. The patch for the kernel source
tree is available at Glomation website in the support page.
Prepare Linux Kernel source
Obtain the kernel source 2.6.33.14 from http://www.kernel.org. Untar the Linux kernel,
tar xjf linue-2.6.33.14.bz2
Obtain the kernel patch from http://ics.nxp.com/support/software/lpc313x.bsp.linux/
. Patch the
kernel source with the following command,
patch –p1 < /<patch-file-directory-path>/patch_file_name
Configure Linux Kernel
The GESBC-3130 can use the default configuration file for the EA3130 evaluation board.
make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnu- ea313x_defconfig
If additional configuration is required, executing the following command in the Linux kernel
directory,
make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnu- menuconfig
If problem occurs, make sure the default PATH variable is set to the correct tool chain directory
Compile Kernel
Once Linux kernel has been configured, it can be compiled using following command,
make ARCH=arm CROSS_COMPILE=arm-unknown-linux-gnu- uImage
The U-boot utility mkimage is required to make the U-boot formatted kernel image files.
