Sorry for the offlist email I hit the wrong button on my phone.

Nice to here it is working. The whole discussion  raises some questions:

- What support period can I suspect from a recent ELDK?
- Are there any Long Term Yocto/ELDK releases planned?

For industrial applications life cycles of 5-10 years are not seldom.

The only feasible approach here is to run in a supported OS environment - either on a phyical or on a virtual machine.  Given that it may be difficult to run such old kernels on current hardware (for example, you may find that there are no drivers for the S-ATA controllers in your PC), it is much easier and much less maintenannce effort to set up a virtual host.
