  • (Not available)

Getting Started

First at all, you should read IGEPv2 SDK User Manual and follow its instructions.

Below steps are a quick and partial summary of IGEPv2 SDK User Manual:

  • Download Ubuntu 8.04 IGEP v2.0 SDK Virtual Machine
  • Uncompress Ubuntu-8.04-IGEP-v2.0-20101124.7z file (Windows users use 7-zip / Linux users use p7zip)
  • Start up uncompressed virtual machine ( 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.
You can do this sourcing once the environment-setup script. 

$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi

Create a single .c file (hello-world.c), using your preferred editor (vi, nano, gedit, ...)

hello-world.c: 

#include <stdio.h> 
int main (int argc, char **argv)
{
  printf("Hello world !\n");
  return 0;
}
  • 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: 

$ 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
  • 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 

$ sudo cp hello-world /srv/nfs/poky/poky-image-sato/igep0020a/home/root
[sudo] password for jdoe: letmein
  • Execute arm executable file inside IGEPv2 board

And run the program in your target device (serial console or ssh network terminal) 

# cd /home/root
# ./hello-world
Hello World !

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 

$ ./configure --target=arm-none-linux-gnueabi --host=arm-none-linux-gnueabi

Now, it shows how you can download the GNU Hello program and build for your device

See log example: 

$ 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

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)


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
jdoe@ubuntu:~$ cat /etc/inetd.conf 
tftp		dgram	udp	wait	nobody	/usr/sbin/tcpd	/usr/sbin/in.tftpd /srv/tftp
  • NFS exported rootfs at "/srv/nfs/poky/poky-image-XXXXX/igep0020/" directories
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)

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

  • 1) Open 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, 

$ 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 < poky-image-minimal-mtdutils-igep0020.rootfs.cpio

Download and copy a pre-built kernel image to poky-image-minimal project 

$ 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

Export the directory tree with an entry in /etc/exports file editing with your preferred editor, like 

/srv/nfs/poky/poky-image-minimal-mtdutils/igep0020   *(rw,no_root_squash,no_subtree_check,sync)

and restart the NFS server 

$ sudo /etc/init.d/nfs-kernel-server restart

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 

# setenv machine igep0020
# setenv project poky-image-minimal-mtdutils
# run nfs-boot
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, 

$ 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 < poky-image-sato-igep0020.rootfs.cpio

Download and copy a pre-built kernel image to poky-image-minimal project 

$ 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

Export the directory tree with an entry in /etc/exports file editing with your preferred editor, like 

/srv/nfs/poky/poky-image-sato/igep0020   *(rw,no_root_squash,no_subtree_check,sync)

and restart the NFS server 

$ sudo /etc/init.d/nfs-kernel-server restart

Now, you can power up your board, stop at u-boot, set the project variable point to poky-image-sato and boot via NFS

Virtual Machine Enhancements (version 20091222)

Software updates

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 'Which Poky SDK toolchain do I have ?' ) 

$ mv /usr/local/poky/eabi-glibc /usr/local/poky/eabi-glibc.20090721

and replace with the new SDK 

$ 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/

Note that with the change in the poky SDK all the lines 

$ source /usr/local/poky/eabi-glibc/arm/environment-setup

should become 

$ source /usr/local/poky/eabi-glibc/environment-setup-arm-none-linux-gnueabi
