Image is working.But I don't know if this is the right way? So any help,suggestions, improvments are welcome.
I think I found the problem, it is a DOT which is used in the name IMAGE_FSTYPES, enough to replace the DOT on the DASH, in all of the files you want:
meta-dream/conf/machine/include/dreambox-ubi.inc
- IMAGE_FSTYPES ?= "ubi.nfi" + IMAGE_FSTYPES ?= "ubi-nfi"
meta-dream/conf/machine/include/dreambox-jffs2.inc
- IMAGE_FSTYPES ?= "jffs2.nfi" + IMAGE_FSTYPES ?= "jffs2-nfi"
......
etc.
