I did a PCB by myself based on the zedboard. Except having no HDMI, Audio, button, all the others are same. I made a SD according to the instruction of www.xillybus.com. It can run on the zedboard, but after I changed to my own PCB, the linux can not run normally.It stop after console [tty0] enabled, bootconsole disabled. The followings are the output from serial port:
In: serial
Out: serial
Err: serial
Net: zynq_gem
Hit any key to stop autoboot: 0
