Description Todor Minchev 2016-12-07 18:18:38 UTC

This is the partition table of hddimg, which seems to be derived from the build host. The image boots OK when deployed to a NUC target, but we'll need to figure out if this is something that can cause issues in the future.

Comment 1 Ed Bartosh 2016-12-08 15:53:05 UTC

Does hddimg have partition table at all?

Comment 2 Ed Bartosh 2016-12-08 15:57:55 UTC

Here is the output of fdisk -l for qemux86-64 machine:

$ /sbin/fdisk -l ./tmp/deploy/images/qemux86-64/core-image-minimal-qemux86-64-2016120223*.hddimg

JFYI: There is a proposal and ongoing activity of getting rid of hddimg: http://lists.openembedded.org/pipermail/openembedded-architecture/2016-December/000359.html

hddimg images infer their partition table from the partition table of the host on which they are generated. Closing this as we are removing hddimg.
