Hi Gerd,
as far as I know, this should work exactly the same way in Dunfell and
Scarthgap. You should perform the usual checks to debug the issue:
- double-check that your image depends on the kernel modules using bitbake
-g core-image-minimal (if not use bitbake -e to check if something is maybe
modifying IMAGE_INSTALL, etc.)
- try bitbake -c clean sstate hello && bitbake hello to see if this
populates the sysroot
- if everything else, keep the downloads directory and rm -rf the rest,
then build core-image-minimal again
