ELDK 5.0 Beta Testing
ELDK Release 5.0 is based on the Yokto Project, a complete embedded Linux development environment with tools, metadata, and documentation - everything you need - driven and supported by the Linux Foundation.
As the Yocto project is nearing it's release 1.0,
scheduled for Apr 6, 2011,
we follow it's progress and provide snapshot builds for testing purposes.
ELDK Release 5.0 will then be based on Yocto Release 1.0,
adding packaging and installation tools as you are used from
previous ELDK versions.
At the moment, only the raw snapshot builds are available,
so there is a little manual action needed for installation and use:
Download the ELDK beta images
The beta images are currently available in the "beta-eldk/"
directory of the DENX FTP server.
We recommend to always use the latest available snapshot build.
Please contact
DENX
for access data.

Here "poky-eglibc-i586-arm-toolchain-*" is the cross tool chain for
ARM targets and x86 hosts,
while "poky-image-*-qemuarm-*.rootfs.tar.bz2"= is a root file system
image for ARM boards.
Installation
As mentioned above, at this point of time there is neither a skin nor
installation tools to provide the familiar ELDK look and feel yet.
Installation has to be done manually instead.
Also, at this point, installation has to be done into the
"/opt/poky/" directory:
- Create necessary directories:
$ sudo mkdir /opt/poky
$ sudo chmod 01777 /opt/poky
$ mkdir /opt/poky/root-6xx
$ mkdir /opt/poky/root-arm
- Install cross tool chain:
$ cd /
$ tar xpf /tmp/poky-eglibc-i586-arm-toolchain-*
You may see a number of warnings and error messages, for example:
tar: ./opt/poky: Cannot utime: Operation not permitted
tar: ./opt/poky: Cannot change mode to rwxrwxr-x: Operation not permitted
tar: ./opt: Cannot utime: Operation not permitted
tar: ./opt: Cannot change mode to rwxrwxr-x: Operation not permitted
tar: .: Cannot utime: Operation not permitted
tar: .: Cannot change mode to rwxrwxr-x: Operation not permitted
tar: Exiting with failure status due to previous errors
These messages are due to the currently used installation method
and can safely be ignored.
- Install target root file system:
$ cd /opt/poky/root-arm
$ sudo tar xpf /tmp/poky-image-*
