Your quoting style is strange. Normally the reply _follows_. Well, if you cannot update, then we cannot help it either. It's yur problem, after all. [Well, of course there are companies that will happily send you a quotation for such an update, in case you are considering a commercial solution.] > > U-Boot is, in it's default configuration, designed to be run on a > > virgin CPU comingg fresh out of reset, so it naturally has to be > > installed at the reset vector of your processor.

It is possible, and it is not so difficult if you have sufficient experience with U-Boot. > Do I have to make big changes to the uboot-source (start.S,..)? This depends on your definition of "big". Judging from the questions you are asking, I tend to say: too big for you. No offence meant. > I could put ~256 bytes of assembly code to the reset-vector at > 0x0A000000 and jmp in the u-boot; but if you say this is not enough, I > will not start to learn the assembly language for my processor. This has nothing to do with using assembly code.
