This page contains a lot of information and programs (sample applications) that will QuickStart your program development!
Note that Embedded Artists does not provide support for the sample applications that can be downloaded from this page. The sample applications have been created in order to ease the development of application programs on the LPC2292 SO-DIMM uClinux Board.
The board exists in two versions; one with and one without a connector for mounting Bluetooth modules from connectBlue.
A uClinux distribution based on Linux 2.4 or v2.6 exist for the board, see below.

uClinux Distribution v2.6
This section contains a description of an uClinux distribution based on v2.6.5. The distribution has been customized for the LPC2292 SO-DIMM uClinux Board.
The bootloader is now based on the u-boot, which is a popular bootloader. Note that all operations described below assumes a linux host. A Windows© host will in general not work.
Distribution Images
Description File
linux.bin
Image of uClinux system. Needed during booting.
(Files updated 2007-02-25) linux.bin (1462kB)
romfs.bin
Initial rom file system. Needed during booting.
(Files updated 2007-02-25) romfs.bin (1442kB)
u-boot
U-boot bootloader (EA version 1.5). Placed in internal FLASH memory of the LPC2292.
(Files updated 2007-04-03) u-boot.hex (258kB)
u-boot.bin (107kB)
Below is a description about how to patch and compile the u-boot.
u-boot patch
The current release builds on u-boot v1.1.6.
Download the u-boot-1.1.6 and unpack. Change directory to u-boot-1.1.6 and type:
gunzip -c where_ever/u-boot-1.1.6-ea_20070105.diff.gz | patch -p1
This will apply the EA specific changes to the source code (for both this board and the LPC2468 OEM Board). Note that this patch will not update to u-boot EA v1.5. A patch for this will be uploaded soon.
For details about how to compile the u-Boot and how to download a new version, see section below.

The patch for u-boot-1.1.6.
(Files updated 2007-01-05) u-boot patch (97kB)
Prerequisites
First of all, you have to download the u-Boot v1.1.6. This can be found from ftp.denx.de or from the Sourceforget project repository.
Download and unpack.
Secondly you have to install ELDK v4.0. ELDK stands for Embedded Linux Development Kit. The ELDK includes the GNU cross development tools, such as the compilers (GCC v4.0), binutils, gdb, etc., and a number of pre-built target tools and libraries necessary to provide some functionality on the target system.
Full instructions about downloading and installing the ELDK can be found on: http://ftp.sunet.se/pub/Linux/distributions/eldk/4.0/arm-linux-x86/distribution/
It's also possible to download a CDROM iso file from: http://ftp.sunet.se/pub/Linux/distributions/eldk/4.0/arm-linux-x86/iso/
It's basically just the compiler that is needed for compiling the u-Boot.
Compiling
Compiling is really simple. First change directory to u-boot-1.1.6. Then make sure the correct target board is selected and then actually compile. The two command lines below accompilish this:
make distclean
make lpc2292sodimm_config
To actually compile and create a u-boot program image, type:
make
Two files are created, named u-boot and u-boot.bin. The first is the elf-file which is not used unless you are debugging the u-boot itself. It is the *.bin file that is normally used. In some cases, this file must be converted to another format before downloaded into the internal FLASH of the LPC2292. It depends on the download tool used. Intel-HEX is for example a commonly used format for many tools.
To convert the *.bin file into a *.hex file, type the command below.
arm-linux-objcopy -I binary -O ihex u-boot.bin u-boot.hex
Booting via TFTP
tftpboot 81008000 linux.bin
tftpboot 81600000 romfs.bin
go 81008000
Booting via MMC/SD
mmc
fatload mmc 0 81008000 linux.bin
fatload mmc 0 81600000 romfs.bin
go 81008000
To get an overview of the MMC/SD memory card, type:
flinfo
To list the content of the MMC/SD memory card, type:
fatls mmc 0
The section below contains patch(es) for upgrading the distribution, i.e., fixing bugs and/or extending functionality.
Incremental updates
Incremental updates are to be applied after all the ordinary patches has been applied to the distribution. Ordinary patches are the ones listed above in the uClinux patch section.
Apply the incremental patch by changing directory to uClinux-dist-20051014 and type:
gunzip -c where_ever/ea-v1_0_incr1.diff.gz | patch -p1
Description File
ea-v1_0_incr1.diff.gz
Incremental patch number 1 with updates to the v1.0 distribution.

Pre-emptive Real-Time Operating System (RTOS)
This section contains a pre-emptive real-time operating system (RTOS) for the LPC2292 SO-DIMM uClinux Board. The RTOS is delivered as a library plus a number of sample applications. It is free to use for non-commercial applications (this also includes company internal projects - products not sold for profit).
RTOS Package
The latest version - v2.2 of the RTOS (updated 2005-10-17) The zip-file contains the library, documentation, and a number of sample applications.
Unzip the archive, start the LPC2xxx-gcc-newlib QuickStart Build Environment and change directory to the root of the archive. Then change directory to the sample project that you actually want to build and type: make deploy to download into your board. Observe that the jumpers on the board must be shorted in order to enable the automatic program download function.
The different sample applications illustrate different functionalities of the RTOS. You can easily extend the sample applications and start creating your own application.
