Device Manager App now shows app_update.bin as an Invalid Image file. On a previous version of the app (pre-2.0.0) this worked. What changes do I need to make to my prj.conf to correct this issue and/or how would I figure out what is causing it to come up this way? I've always used 'Test and Confirm' and 'Basic' mode for dfu.
As a side note, attempting to use dfu_application.zip instead produces a State of 'Corrupt(9)'. This way of doing a dfu has never worked.
Here is the prj.conf I have:
