Most of the time you can't select broken combinations with PTXdist. But maybe
not all combinations are tested here. A dangerous source of broken
configurations is the "ptxdist migrate" step. That's why it must be done very
carefully.

Welcome to the world of advanced configuration. ;)
Sometime PTXdist gets confused, what package is to be built again. This can
happen, if you select and deselect various settings, give it a try here and
there and so on.
Here is a list, what you can try in this case:
- clean the package that fails and build it again
$ ptxdist clean <package-name>
$ ptxdist go
- if it still fails, it could be a dependency which makes it fail.
In this case we need to go the hard way, by re-building everything:
$ ptxdist clean
$ ptxdist go
- if it still fails, send us:
- what BSP you are using (name and version)
- what PTXdist version you are using to build the BSP
- a copy of the currently used 'selected_platformconfig' and
'selected_ptxconfig'
- the logfile 'platform-mini2440/logfile'
This information enables us to reproduce what you have done.
Regards,
Juergen
