Robert, Thanks for the quick reply. I tried my OPD-LCD5-03-00A0.dtbo overlay with the latest Ubuntu console image (7/14), and it also hangs.
I checked the sizes of the overlays for BB-BONE-LCD7-01-00A3.dtbo, which I use with a BBB, and the one I got (probably from an old Debian build), is a significantly different size than the one that comes with 4.14.54-ti-r63. I noticed you suggested in another post on a related topic to get the latest DTC, and I will do that -- Very likely I am working with an old compiler, and am therefore incompatible.
