[yocto] Extensible SDK and DEFAULT_PREFERENCE

[Martin Siegumfeldt]

Hi,

I am having a number of recipes residing in two versions, some (development versions) being down-prioritized using:

DEFAULT_PREFERENCE = "-1"


The source code is hosted at a private git repository, and the git version is selected using 'AUTOREV'. The extensible SDK renders successfully, however the installation (by third party) fails:

Traceback (most recent call last):

Please make sure you have the correct access rights
and the repository exists.

It is not the intention that third party will ever need access to the development version, and I don't see why the version information is fetched given the reduced priority. Have I encountered an 'undocumented bug' or is there an alternate approach to achieve this?

Thanks,
Martin
