Download QEMU sources from linaro git repository:
<pre>$ [http://git.linaro.org/gitweb?p=qemu/qemu-linaro.git;a=summary git clone git://git.linaro.org/qemu/qemu-linaro.git]</pre> Download IGEP support patch for QEMU from this [http://downloadswww.igepisee.esbiz/component/zoo/QEMUitem/0001qemu-IGEP_QEMU_support.path emulator link ]and after that apply the patch as:
<pre>$ cd qemu-linaro
$ patch -p1 < 0001-IGEP_QEMU_support.path</pre>
Configure the sources for build with this command:
<pre>$ ./configure --target-list=arm-softmmu --prefix=<span style="color: rgb(255, 0, 0);">/opt/qemu-linaro</span></pre>
Build the sources:
<pre>$ make </pre>
Install QEMU:
<pre>$ make install</pre>Optionally you can download from [http://downloadswww.igepisee.esbiz/QEMUcomponent/zoo/item/qemu-linaro.tar.gz emulator here] the QEMU binaries, we suggest install it under /opt directory with the right user execution permissions.<br>
== Board Emulation ==
Go to your qemu install directory.<br> <pre>$ cd /opt/qemu-linaro/bin</pre> We provide a QEMU ready image based on Ubuntu/Linaro Nano (Oneric 11.11) image, it can be download from [http://www.isee.biz/component/zoo/item/qemu-emulator here] (first uncompress it).<br>
$ cd /opt/qemuThe image has 2 partitions (you can see the partitions using fdisk -linaro/binul command as: fdisk -ul igep-nano.img)<br>

Optionally you can mount the partitions in you host PC and modify the content as:<br> <pre>First Partition: $ mount -o loop,offset=$[63*512] igep-nano.img1 img /mnt/tmp</pre><pre>Second Partition: $ mount -o loop,offset=$[106496* 63 106494 53232 c FAT32 LBA (Boot)512] igep-nano.img /mnt/tmp</pre> Now you're ready for execute the emulator in a console with this command:<br> <pre>qemu-system-arm -M igep -m 512 -clock unix -serial stdio -drive file=igep-nano.img,if=sd,cache=writeback -usb -monitor telnet:localhost:7100,server,nowait,nodelay -device usb-kbd -device usb-mouse</pre> Parameters:<br>

Optionally you can mount the partitions in you host PC and modify the content [[Image:QEMU boot.png|thumb|center]] == Tips == === Resize Rootfs Partition === We will resize our rootfs partition adding 1 GB at end. First we create a new raw file using qemu-img as:<
brpre>
$ qemu-img create -f raw addon.raw 1G <
/pre>
First PartitionWith addon.raw we concatenate it at end of our image file as:
<pre>$
mount -o loop,offset$[63*512] cat addon.raw >> igep-nano.img
/mnt/tmp</pre>
Next step it's modify the partition table information. We will use cfdisk utility for modify the information. <pre>
Second Partition: $
mount -o loop,offset$[106496*512] sudo cfdisk igep-nano.img
/mnt/tmp </pre>
Now youNext step it'
re ready for execute s select your rootfs partition as this picture shows [[Image:Cfdisk change size partition.png|thumb|center]]Select the
emulatormenu '''RESIZE''' and select '''CHANGE SIZE''' option. [[Image:Cfdisk change size partition option.png|thumb|center]]Select resize at '''END'''. [[Image:
<br>Cfdisk resize end.png|thumb|center]]Enter the MAX new size and press enter key. We will write the changes to the disk using the '''commit''' menu option and select '''YES''' (confirm the changes). The next step it's update the file-system structure. <pre>
