=== Which IGEP SDK Virtual Machine do I have  ? ===

At this moment (2010-December), your IGEP SDK Virtual Machine could be:

== Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine (version 20101124) ===== Overview (version 20101124) ===* This is the lastest available IGEP SDK Virtual Machine (2010-December)

* IGEPv2 boards could boot from TFTP+NFS exported installed demos

* It provides installed demos at "/srv/" directory** TFTP exported Linux kernels at "/srv/tftp/poky/poky-image-XXXXX/igep0020/uImage" files** NFS exported rootfs at "/srv/nfs/poky/poky-image-XXXXX/igep0020/" directories

* It provides a compiled toolchain demo at "/usr/local/poky/eabi-glibc" directory * There is a project source code example at "/home/jdoe/staging/x-loader/" directory, that is git cloned from http://git.igep.es public source code repositories* It is based on Ubuntu 8.04.4 distribution* It provides quick links to ISEE IGEP boards ecosystem* What's New:** OMAP3730 processor support** Upgraded toolchain

<br> <br>

=== 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 fileFirst 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>

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;

printf("Hello world &nbsp;!\n");

</pre>*Build arm binary executable

* Build arm binary executableCross 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-gnuabignueabi-gcc -o hello-world hello-world.c

</pre>*Transfer arm executable file from virtual machine to IGEPv2 board

* Transfer arm executable file from virtual machine to IGEPv2 boardCopy 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

</pre>*Execute arm executable file inside IGEPv2 board

<pre># cd /home/root

Hello World &nbsp;!</pre>==== Example 2: Hello world (built with autotool+cross toolchain) ====

<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

</pre>=== Demos (version 20101124) ===

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

</pre><br> * NFS exported rootfs at "/srv/nfs/poky/poky-image-XXXXX/igep0020/" directories

*NFS exported rootfs at "/srv/nfs/poky/poky-image-XXXXX/igep0020/" directories<pre>jdoe@ubuntu:~$ cat /etc/exports

</pre>If you want use these demos, IGEPv2 should boot with network TFTP+NFS method. Let show it:

If you want use these demos, IGEPv2 should boot with network TFTP+NFS method.Let show it:* 1) Open [[Serial_Debug_ConsoleSerial Debug Console|debug serial port]] and configure U-Boot environment variables. Press any key when you see:<pre>Hit any key to stop autoboot: 5 </pre> Bootlog:<pre>60

</pre>* 2) Now, you are inside U-Boot prompt. Configure U-Boot environment variables with:<pre>U-Boot # setenv project poky-image-sato

</pre> All your environment variables should be similar to:<pre>U-Boot # printenv

onenand-bootargs=setenv bootargs ${bootargs-base} root=/dev/mtdblock4 rootfstype=jffs2 &nbsp;; run addiponenand-boot=run onenand-bootargs; onenand read 0x80000000 0x280000 0x300000 &nbsp;; bootm 0x80000000nfs-bootargs=setenv bootargs ${bootargs-base} root=/dev/nfs nfsroot=${serverip}:/srv/nfs/${distro}/${project}/${machine} &nbsp;; run addip

</pre> Now, we can boot with TFTP+NFS method<pre>U-Boot # run nfs-boot

</pre><br>

* 3) When you get system up, login and check your boot method

See "root=/dev/nfs" and "nfsroot=192.168.254.10:/srv/nfs/poky/poky-image-sato/igep0020" in boot Linux cmdline string parameter:

=== HOWTOs === 

==== The bootloader X-loader ==== [[The_bootloader_XThe bootloader X-loader|This HOWTO]] should be readed for advanced developers who wants hacking first stage bootloader. ==== The bootloader U-Boot ==== [[The_bootloader_UThe bootloader U-Boot|This HOWTO]] should be readed for developers who wants hacking second stage bootloader and change some board features (GPIO MUX configuration, rootfs location,...) ==== The Linux kernel ==== [[The_Linux_kernelThe Linux kernel|This HOWTO]] should be readed for developers who wants hacking IGEP Linux kernel and built-in drivers. People who knows hardware and ajusts Linux kernel feature. Also, developers who add more feature to Linux kernel like network protocol, new filesystems, patching buggy Linux kernel,... ==== How to upgrade and recover the factory firmware ====

==== [[How to upgrade and recover the factory firmware ====[[How_to_upgrade_and_recover_the_factory_firmware|This HOWTO]] should be readed for USERS who wants change enviroment configuration and default boot sequence of IGEPv2. You need connect your workstation to IGEPv2 board with UART3 serial debug port (USB to serial converter + DB9-IDC cable to J960 IGEPv2 connector).

=== OTHER REFERENCES === ==== Frequency Asked Questions (FAQ) ==== Useful webpage is "[[Frequently Asked Questions and Their Answers|Frequency Asked Questions]]" or [[Frequently Asked Questions and Their Answers|FAQ]] page. Users could find common questions about IGEPv2 board and very quick answers about IGEPv2 software and hardware issues.  ==== FORUM ==== Free [[http://www.igep.es/forum/|IGEP Support Forum]] could be found a lot of knowledge. People who has some issue, they should read forum threads. Then, if you don't find anything about your issue, you should write new post.
