Description
I keep getting this error when I try run reSnap.sh. I am working with a mac and a remarkable 2, running software version 3.16.2.3.

Some inspection suggested that the memory map after /dev/fb0 is just too small to be the frame buffer, ranging from addresses 6fe00000-6ff00000.
The relevant lines of the map file:
6dcdc000-6e642000 rw-p 00000000 00:00 0
6e642000-6fe00000 rw-s a9d00000 00:06 1138 /dev/fb0
