[meta-xilinx] Problem with Xilinx QEMU & Yocto Flow

[SMITH Peter T]

Hi,

I am trying to run Xilinx's QEMU (as built by meta-xilinx release 2016.3) and am receiving the following error

qemu: RAM size must be less than 4GB to boot Linux kernel using ATAGS (try passing a device tree using -dtb)

on running ../sources/meta-xilinx/scripts/runqemu qemuzynqmp as instructed here http://www.wiki.xilinx.com/QEMU+Yocto+Flow

Any clues as to what is wrong?

Here is the log
peter at peter-VirtualBox:/yocto/peter/CSP/build$ ../sources/meta-xilinx/scripts/runqemu qemuzynqmp

Continuing with the following parameters:
