This howto will show you how to quickly and easily set up an ARM toolchain so that you can use openembedded. You can also use this toolchain to compile the linux kernel or anything else that you specifically want to compile for the mini2440.
Download the toolchain here.
After you've downloaded the toolchain, you can untar it into your /usr/local directory or somewhere in your home directory if you don't have root access to the machine you're compiling on.
UBoot must usually be installed in a Flash memory to be
executed by the hardware. Depending on the hardware, the installation of UBoot
is done in a different way
The board provides some kind of specific boot monitor, which allows to flash the second stage bootloader. In this case, refer to the board documentation and tools UBoot is already installed, and can be used to Flash a new version of UBoot.
However, be careful: if the new version of UBoot doesn't work, the board is unusable
The board provides a JTAG interface, which allows to write to the
Flash memory remotely, without any system running on the board. It
also allows to rescue a board if the boot loader doesn't work.
mkdir uboot ;
cd uboot git clone git://repo.or.cz/u-boot-openmoko/mini2440.git

Micro2440 with Linux and U-Boot
Micro2440 Instructions for U-Boot and Linux
A brief introduction about how to get started with the Micro2440 boards and u-boot.
We are going to replace all contents of the NAND flash - so make sure to have a backup if there is any valuable data on your device.
What we need
* Micro2440 SDK
* Linux PC (Windows would work as well but I'm not sure how to upload files to Vivi with it.)
* SD/MMC card
* Serial cable
* USB cable or JTAG (to replace vivi)
