Hello,
We have a rev D ZedBoard and v2014.1 of the Xilinx tools. I am working my way through the tutorials in zedboard_CTT_v2013_2_130807.pdf from zedboard_CTT_v2013_2_130807.zip. Because it is for v2013.2 there have been a number of issues I've had to get around, but I'm stuck on this one.
In chapter 5 "Booting Linux and Application Debugging Using SDK", I got as far as beginning the linux boot (5.2.3 step 7). Some time into the boot the ZedBoard hangs, suspiciously after some non-ASCII output. The terminal output is attached below.
When the jumpers are in SD card boot configuration it boots the out-of-the-box linux on the SD card.
Terminal output:
