That will work. The current project is 120M in size. That includes some c
test code. The project is
run from a windows environment. However my uclinux builds are being done in
a vmware session hosting
linux. So you will need to setup your own build environment for that part.
Also please keep your replies on the list (unless you are sending password
information), so that
others can benefit from anything we may figure out.
I can not guarantee any of this will work for you. As I said, I have been
having timing problems. It is possible
that your fpga may differ enough that the timings will break things. I will
supply more detailed information
about how things are laid out after everything is uploaded and available.
