I would rather not use the ultracontroller design anymore. I want to create a
EDK project from scratch, add a plb buss, add a few peripherials(gpio and
uart). Doesnt sound like i am asking for the world but i am having a tough time
finding some simple instructions on how to do it.

anybody know where i can find some instructions for this?

Well, I can only tell you how I learned to use the EDK (no tutorial,
sorry): use the included wizard to generate a basic system for one of
the supported boards, for example the ML300, and then either start from
this (and make whatever changes to the UCF), or read through the
generated files to understand them. Since the ML300 supports gpio and
uarts, the wizard should generate all the necessary components, i.e.
ppc, plb, plb2opb, opb, opb_gpio, opb_uart16550.


Good luck. EDK really isn't that hard to use :-)

My approach was to take an existing project, and then figuring out how
the pieces went together. I found the EDK gui to be more trouble than it
is worth, at least for me.

The fundamental thing to notice is that the EDK "project" is really just
a makefile, generally system.make, that is created by the GUI. This
makefile can be executed manually on the command line. When you run the
makefile, it invokes a bunch of programs, and you can see what it is
invoking and with what parameters.

Each command invoked is documented somewhat (though the documentation as
usual is somewhat lacking), so looking up how each command was invoked
allows you to soon figure out what it is doing. Then to make changes, I
just add and remove pieces and edit the the project files manually. The
inevitable resulting error messages generally have been enough to steer
me in the right direction.
