What CPU do you have? Is CN700 usable exclusively with C7? What
generation C7 do you have? Does VIA have updated setup code for
your model CPU?

So code at 9ff66 is trying to jump to a0000. This is all sorts of
wrong. Start by looking at what is going on at 9ff66. Obviously make
sure that your toolchain is working. I believe VIA startup has some
assembly. Verify that your disassembled binaries have 1:1 of the
source. All basic bringup.

No, I don't think anyone is.

A more precise reference to the code you have in mind would allow
more efficient collaboration.
