A lot of u-boots I've found point to a ramdisk filesystem instead of a

Not trying to do anything fancy; just trying to reproduce Jonathan Pendlum's 
FFT filter example, which was written back when that ancient stuff was current. 
I think it'd be good for that to be updated for people who want to run GNU 
Radio on Zynq. I know RFNoC will change how that's done with E310, but we don't 
need RFNoC for MicroZed/ZedBoard/ZC70x. I'm happy to help with the writeup 
if/when I figure all this out.

I'll try your newer image.
