 If something goes wrong during an attempt to replace the u-boot already installed, and you can be sure that something will go wrong, you need to restore the previous configuration. That means basically that you have to load the last working u-boot version you have (normally the one given by SSV in the sk28 kit).

 === The UBOOT ===
 I use the uBoot compiler, which is the one provided with the target. But this one is too old to be able to use new uClinux images, so a new version of uBoot is also required.
