Which IGEP SDK Virtual Machine do I have ?

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

  • 20101124 version ( based on: Ubuntu 8.04.4 + Poky 20101124 version + IGEP0020-RC )
  • 20091222 version ( based on: Ubuntu 8.04.1 + Poky 20090721 version + IGEP0020-RB )

Which Poky SDK toolchain do I have ?

You could see "Poky SDK toolchain" version at: 

jdoe@ubuntu:~$ cat /usr/local/poky/eabi-glibc/version-arm-none-linux-gnueabi
Distro: poky
Distro Version: 3.2.1
Metadata Revision: 949b440e52d637ef52eadb50c87e615eebd64ed4

Which Poky SDK toolchain do I have ?

You could see "Poky nfs exported rootfs" version at: 

jdoe@ubuntu:~$ cat /srv/nfs/poky/poky-image-sato/igep0020/etc/version 
201011231602

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

Overview (version 20091222)

  • Older IGEP SDK Virtual Machine (2009-December)

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

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
