Xapp1078 - uboot hangs on "[..]unable to open rtc device (rtc0)"

i tried to run xapp1078 on my microzed board. The goal is to run linux on CPU0 and a standalone file on CPU1. I use this download example:
I'm using Vivado 2014.4 as well as petalinux 2014.4
therefor I installed the microzed bsp for petalinux:
I think i have done everything linke in the description. I just changed in the .tcl file the devide part to 7z020:
# Set project properties
set obj [get_projects $proj_name]
set_property "part" "xc7z020clg400-1" $obj
set_property "target_language" "Verilog" $obj
set_property board_part $obj

everthing compiles completely but when i try to boot from SD card, the following code hangs on the last line.
Does someone knows the problem? i cant find it...
.... done
