MicroZed Linux Booting Using JTAG Mode

I tried to boot Linux using JTAG using sample boot image from ug873-design-files. The process halts at the last line and I have no idea what is going on.

Putty screen shot below:

UG873 targets the Xilinx

UG873 targets the Xilinx ZC702 board and will not work for the MicroZed. There are versions of the Zynq Concepts, Tools and Techniques tutorial for the ZedBoard here: http://www.microzed.org/support/design/1521/11 , with the latest version for Vivado 2013.4, but it may have issues with the MicroZed as well.
 
There are some basic tutorials for the MicroZed here: http://www.microzed.org/support/design/1519/10
 
Adam Taylor has a good blog on using the MicroZed board starting here: http://forums.xilinx.com/t5/Xcell-Daily-Blog/Bringing-up-the-Avnet-Micro...
 
 
The Avnet Zynq Hardware, Software, and PetaLinux Speedway design workshops have labs that target either the ZedBoard or the MicroZed and can be downloaded here: http://www.microzed.org/support/trainings-and-videos
