could not compare disk images with partition table
Hi,
I am using diffscope to compare two disk images that are created using yocto wks files that means the image has partition table and they are not comparing using diffoscope tool.
Below is the debug output of diffoscope
$ diffoscope --debug image1.wic image2.wic
