The
bootcmd setting of the U-boot reads the Linux kernel from NAND FLASH at address
0x100000 to SDRAM at address 0x31000000 and start executing the kernel code at the same
memory address. The NAND FLASH from 0x400000 and up is used for Linux root file system.
The U-boot passes the MTD device pa rtition setting to the Linux kernel via the
bootargs
environment variable.
Loading Linux Kernel and root File System
The U-boot boot-loader provi des many ways to load Linux kernel and file s ystem into FLASH
memory. The loading by MMC/SD card is shown here. User can consult U-boot man ual for other
methods of loading data.
After power on the GESBC-3130S board, stop the U-boot auto-execution by press any key. The
SD/MMC card must initialized before can be used. The SD/MMC card must have a FAT as its
first partition. The data files can be stored in the FAT partition. The following command
sequence shows the steps to load Linux kernel image and store it in the SDRAM,
GESBC-3130S User’s Manual
Version 1.0 Page 16 of 19 4-Mar-13
mmc init 0
fat load mmc 0 0x30000000 uImage
The NAND FLASH sectors must be erased first bef ore new ke rnel image can be stored. The
following command will erase t he N AND 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 0x30000000 0x100000 0x200000
The following commands can be used to load root file system into the FLASH memory,
nand erase 0x400000 0x7c00000
fatload mmc 0 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. The $(filesize)
instruct the U-boot automatically calculate the size from data file that was just loaded.
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 availabl e 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 thro ug h 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 Gl omation website in the support page. A host
PC running Linux operating system is require d to run the development tools. This guide assumes
user had basic Linux or Unix application develo pment 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-3130S to the host computer.
Install Linux Development Tool Chain
The ARM Linux Development Tool cha i n ca n b e installed in any directory on the h ost system.
The following example uses cross compiler default directory /usr/local/a rm 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-4.2.3-
glibc-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-linux-
gnu/bin:$PATH

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-3130S 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 config ured, 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.
