The testapps are generated using a different linker script.

Based on what you sent out, it looks like your EDK design has a memory
at 0x10000000, but this is
not reflected in the linux image you've generated.  This makes me
suspect that you haven't generated the BSP and copied the appropriate
xparameters file over xparameters_xup.h (assuming you are using
CONFIG_XILINX_XUPV2P).
