I have also tried to build a kernel and root filesystem for Zynq but

Poky denzil and Poky danny.

Also the alternate meta-zynq layer from git.yoctoproject.org shows
the same
behaviour.

These are the last console messages which I get:

Instead of using Linux kernel version 3.5-xilinx I always get
Linux-3.2.11-yocto-standard which is obviously missing the
Zynq patches.

meta-zynq/recipes-kernel-linux-zynq contains the following lines:
LINUX_VERSION ?= "3.5"
LINUX_VERSION_EXTENSION ?= "-xilinx"

How can I force Yocto to build kernel 3.5-xilinx?
From you messages, I infer that you are using the meta-zynq layer
located here:

http://git.yoctoproject.org/cgit/cgit.cgi/meta-zynq/

For my builds, I used Philip Ballister's meta-zynq layer located here
for the simple reason that it uses xilinx git repository:

https://github.com/balister/meta-zynq
And in case anyone is wondering, efforts are (still) underway to
get a single unified layer for this board (and others), but getting
all the moving parts organized is taking a bit longer than expected
or than we would like.
Thanks! Should we go ahead and set the list up so interested parties can
start coordinating our existing work?
I'm good with that. It's no big commitment to anything in particular
to have list available, and hopefully it'll serve to draw the right
folks into the conversation.

Cheers,

Also, try to ensure that you don't put both the meta-layers in your
bblayers.conf file
while building, and ensure that you set machine as follows in your
local.conf file

MACHINE ?= "zynq-zc702"

Do let me know how it goes!
