Hi,
This thread is diverging somewhat, so I'll try to focus on the basic question: What is it that you want to accomplish?
If all you want is communication between the Windows host and the Zedboard's ARM processor, you don't need anything loaded on the FPGA (PL) side, and Xillybus has nothing to do with this. Just load the ARM processor with whatever application software you want, and let the data through the USB/UART cable. No Linux, no Xillybus.
If you want the ARM processor to communicate data with the FPGA (PL) side of the Zynq chip, you may use Xillybus for that, but only if some kind of Linux runs on the Zynq's ARM processor. It could be some minimal Linux set, possibly small enough to fit the QSPI flash -- but it has to be Linux, and Xillybus' drivers must be part of it, either compiled into the kernel or as kernel modules.
Regards,
Eli
