==== Upgrade the Poky's SDK  ====

*(Not available)

=== Getting Started  ===

First at all, you should read [http://www.igep.es/index.php?option=com_content&view=article&id=99&Itemid=112&dir=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2/SW_User_Manuals IGEPv2 SDK User Manual] and follow its instructions. 

Below steps are a quick and partial summary of [http://www.igep.es/index.php?option=com_content&view=article&id=99&Itemid=112&dir=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2/SW_User_Manuals IGEPv2 SDK User Manual]:<br> 

*Download [http://www.igep.es/index.php?option=com_content&view=article&id=99&Itemid=112&dir=%2Fvar%2Fwww%2Fvhosts%2Figep.es%2Fhttpdocs%2Fdownloads%2F01-ISEE_Products%2FIGEPv2%2FSW_Tools_SDK%2FSDK Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine] 
*Uncompress Ubuntu-8.04-IGEP-v2.0-20101124.7z file (Windows users use [http://www.7-zip.org/ 7-zip] / Linux users use [http://p7zip.sourceforge.net/ p7zip]) 
*Start up uncompressed virtual machine ( [http://www.vmware.com/products/player/ VMware Player], kvm, qemu, VirtualBox…). 
*Log on virtual machine login (Username: '''jdoe''' / Password: '''letmein''' / Default IP address: '''192.168.254.10''' )

=== Examples  ===

==== Example 1: Hello world (built with cross toolchain)  ====

*Power up your Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine

Power up your development environment and login into bash shell 

*Create source code text file

First of all you need to initialize a suitable environment in the bash shell console inside your virtual machine. <br> You can do this sourcing once the environment-setup script. 
<pre>$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
</pre> 
Create a single .c file (hello-world.c), using your preferred editor (vi, nano, gedit, ...) <br> <br> hello-world.c: 
<pre>#include &lt;stdio.h&gt; 
int main (int argc, char **argv)
{
  printf("Hello world&nbsp;!\n");
  return 0;
}
</pre> 
*Build arm binary executable

Cross toolchain tools are available into the built-in virtual machine Poky SDK. You only need open bash terminal prompt and write commands: 
<pre>$ arm-none-linux-gnueabi-gcc -o hello-world hello-world.c
$ file hello-world
hello-world: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.6.14, dynamically linked (uses shared libs), not stripped
</pre> 
*Transfer arm executable file from virtual machine to IGEPv2 board

Copy the binary result to your NFS-mounted root filesystem on your local virtual machine path 
<pre>$ sudo cp hello-world /srv/nfs/poky/poky-image-sato/igep0020a/home/root
[sudo] password for jdoe: letmein
</pre> 
*Execute arm executable file inside IGEPv2 board

And run the program in your target device (serial console or ssh network terminal) 
<pre># cd /home/root
# ./hello-world
Hello World&nbsp;!
</pre> 
==== Example 2: Hello world (built with autotool+cross toolchain)  ====

Using the SDK with autotool enabled packages is straightforward; just pass the appropriate host option to configure 
<pre>$ ./configure --target=arm-none-linux-gnueabi --host=arm-none-linux-gnueabi
</pre> 
Now, it shows how you can download the GNU Hello program and build for your device <br> <br> See log example: 
<pre>$ wget http://ftp.gnu.org/gnu/hello/hello-2.4.tar.gz
$ tar xzvf hello-2.4.tar.gz
$ cd hello-2.4
$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
$ ./configure --target=arm-none-linux-gnueabi --host=arm-none-linux-gnueabi
$ make
$ file src/hello
src/hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), for GNU/Linux 2.
$ scp src/hello root@192.168.254.254:/home/root
</pre> 
=== Demos (version 20101124)  ===

==== Rootfs demos using an NFS-TFTP environment for IGEP v2  ====

IGEP SDK Virtual Machine comes with 2 installed demos: 

*poky-image-sato (271M) 
*poky-image-minimal (137M)

<br> 

You could find these demo on TFTP (Linux kernel) and NFS (rootfs) exported directories. 

*TFTP exported Linux kernels at "/srv/tftp/poky/poky-image-XXXXX/igep0020/uImage" files
<pre>jdoe@ubuntu:~$ cat /etc/inetd.conf 
tftp		dgram	udp	wait	nobody	/usr/sbin/tcpd	/usr/sbin/in.tftpd /srv/tftp
</pre> 
<br> 

*NFS exported rootfs at "/srv/nfs/poky/poky-image-XXXXX/igep0020/" directories
<pre>jdoe@ubuntu:~$ cat /etc/exports 
# /etc/exports: the access control list for filesystems which may be exported
#		to NFS clients.  See exports(5).
#

# Poky rootstraps
/srv/nfs/poky/poky-image-sato/igep0020		*(rw,no_root_squash,no_subtree_check,sync)
/srv/nfs/poky/poky-image-minimal/igep0020	*(rw,no_root_squash,no_subtree_check,sync)
</pre> 
If you want use these demos, IGEPv2 should boot with network TFTP+NFS method. Let show it: 

*1) Open [[Using serial debug port to communicate|debug serial port]] and configure U-Boot environment variables. Press any key when you see:

== Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine (version 20091222)  ==

=== Overview (version 20091222)  ===

*Older IGEP SDK Virtual Machine (2009-December)

=== Demos (version 20091222)  ===

==== Rootfs demos using an NFS-TFTP environment for IGEP v2  ====

The simplest way to create a new NFS-TFTP environment for IGEP v2 is to use an already working filesystem and pre-built kernel image. Pre-built images are also available. 

===== poky-image-minimal-mtdutils - A small image, just enough to allow a device to boot  =====

Download and install the root filesystem image (poky-image-minimal-mtdutils-igep0020.cpio) as root on the NFS server, 
<pre>$ sudo mkdir -p /srv/nfs/poky/poky-image-minimal-mtdutils/igep0020
$ cd /srv/nfs/poky/poky-image-minimal-mtdutils/igep0020
$ sudo wget http://downloads.igep.es/poky/purple-3.2/v3.2.1-0/images/poky-image-minimal-mtdutils-igep0020.rootfs.cpio
$ sudo cpio -idm &lt; poky-image-minimal-mtdutils-igep0020.rootfs.cpio
</pre> 
Download and copy a pre-built kernel image to poky-image-minimal project 
<pre>$ sudo wget http://downloads.igep.es/poky/purple-3.2/v3.2.1-0/kernel/uImage-2.6.28-r4-igep0020-20100331100327.bin
$ sudo mkdir -p /srv/tftp/poky/poky-image-minimal-mtdutils/igep0020
$ sudo mv uImage-2.6.28-r4-igep0020-20100331100327.bin /srv/tftp/poky/poky-image-minimal-mtdutils/igep0020/
$ sudo ln -s uImage-2.6.28-r4-igep0020-20100331100327.bin /srv/tftp/poky/poky-image-minimal-mtdutils/igep0020/uImage
</pre> 
Export the directory tree with an entry in /etc/exports file editing with your preferred editor, like 
<pre>/srv/nfs/poky/poky-image-minimal-mtdutils/igep0020   *(rw,no_root_squash,no_subtree_check,sync)
</pre> 
and restart the NFS server 
<pre>$ sudo /etc/init.d/nfs-kernel-server restart
</pre> 
Now, you can power up your board, stop at u-boot, set the project variable point to poky-image-minimal-mtdutils and boot via NFS 
<pre># setenv machine igep0020
# setenv project poky-image-minimal-mtdutils
# run nfs-boot
</pre> 
===== poky-image-sato - X11 image with Sato theme and Pimlico applications.  =====

Download and install the root filesystem image (poky-image-sato-igep0020.cpio) as root on the NFS server, 
<pre>$ sudo mkdir -p /srv/nfs/poky/poky-image-sato/igep0020
$ cd /srv/nfs/poky/poky-image-sato/igep0020
$ sudo wget http://downloads.igep.es/poky/purple-3.2/v3.2.1-0/images/poky-image-sato-igep0020.rootfs.cpio
$ sudo cpio -idm &lt; poky-image-sato-igep0020.rootfs.cpio
</pre> 
Download and copy a pre-built kernel image to poky-image-minimal project 
<pre>$ sudo wget http://downloads.igep.es/poky/purple-3.2/v3.2.1-0/kernel/uImage-2.6.28-r4-igep0020-20100331100327.bin
$ sudo mkdir -p /srv/tftp/poky/poky-image-sato/igep0020
$ sudo mv uImage-2.6.28-r4-igep0020-20100331100327.bin /srv/tftp/poky/poky-image-sato/igep0020/
$ sudo ln -s uImage-2.6.28-r4-igep0020-20100331100327.bin /srv/tftp/poky/poky-image-sato/igep0020/uImage
</pre> 
Export the directory tree with an entry in /etc/exports file editing with your preferred editor, like 
<pre>/srv/nfs/poky/poky-image-sato/igep0020   *(rw,no_root_squash,no_subtree_check,sync)
</pre> 
and restart the NFS server 
<pre>$ sudo /etc/init.d/nfs-kernel-server restart
</pre> 
Now, you can power up your board, stop at u-boot, set the project variable point to poky-image-sato and boot via NFS

==== Upgrade the Poky's SDK (from 20090721 version to 20100331 version)  ====

Backup current SDK (If you don't know Poky SDK version, you could see [[Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine#Which_Poky_SDK_toolchain_do_I_have_.3F|'Which Poky SDK toolchain do I have ?' ]] ) 
<pre>$ mv /usr/local/poky/eabi-glibc /usr/local/poky/eabi-glibc.20090721
</pre> 
and replace with the new SDK 
<pre>$ mkdir tmpdir
$ cd tmpdir
$ wget http://downloads.igep.es/poky/purple-3.2/v3.2.1-0/sdk/poky-eabi-glibc-i586-arm-toolchain-sdk-3.2.1.tar.bz2
$ tar jxf poky-eabi-glibc-i586-arm-toolchain-sdk-3.2.1.tar.bz2
$ mv usr/local/poky/eabi-glibc /usr/local/poky/
</pre> 
Note that with the change in the poky SDK all the lines 
<pre>$ source /usr/local/poky/eabi-glibc/arm/environment-setup
</pre> 
should become 
<pre>$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
</pre>
