[Bartosh, Eduard]

JFYI: I’ve answered Martin’s question on the yocto mailing list: https://lists.yoctoproject.org/pipermail/yocto/2018-January/039635.html

    Well, the only prerequisite is the image created properly, with holes.
    The partition does not matter then.
    
    Bmap-tools was added to wic in Yocto, AFAIK, but I never used
    wic/yocto. May be one of the folks in CC knows?
    
    I do not know dfu-util either, so I di not know for sure what it takes
    to make it use bmat-tools. I guess you or someone should just try and
    see.
