Using FMCADC2 with VC707

I'm currently trying to get data down from the FMCADC2 using the VC707. I have followed the instructions from the following wiki:

Withthis code, I was only fully program the VC707 two out of fifty times. The xmd command hangs up indefinitely, but sometimes it does work. I'll talk more on this issue below. I can hook up the UART and log in as root.  Additionally, with this code I can run Vivado and use the ILA tool to get data samples. In the follow thread, I was given a tcl script to interpret the data:

 

Getting Data From FMCADC2 from VC707

 

However, the ADC data using this TCL script is not good. I expected noise, but I get jumps in data with no input. I have seen in other documentation that I'm not sure I can attach due to NDA, but I need to configure the ADC using SPI. Every example of this using the Zynq board, but none for the VC707.

Guide of What I want to do. the VC707 links to GIT, but its only the HDL code and not software support.

I finally found some sort of software support using the above link. In this thread,  it would load but nothing happened. I looked at the UART, but nothing was printed out.

A vast majority of the time I couldn't see anything. My ILA core was not showing up because I would get this issue: "ERROR: [Labtools 27-147] vcse_server: XSDB Master timed out." I saw this link that suggests that FMCADC2 board is bad?

So I have two VC707s and two FMCADC2 boards, and I tried all combinations and I get this error message. I checked the voltage test points on the ADC, and they look like good voltages (12V, 1.3V, and 3.3V). I highly doubt both of my VC707 boards and FMCADC2 boards are bad.
