Copied memory block seemingly too small for frame buffer
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
6fe00000-6ff00000 rw-p 00000000 00:00 0
That is unfortunate. Thank you for the detailed report.
Let me see, whether I can do something about it.
Sorry, I could not reproduce this. I am also using the reMarkable 2 and am on version 3.11.2.5

It is a little strange that I am 2 major versions behind the ffmpeg version you are using...
Update:
I have now also tested it with ffmpeg versions 6 and 7. Still works for me.
Update 2: Ok the update did not load correctly, I could reproduce this. Will take a look at it
I am also getting this issue on my Remarkable 2, software version 3.16.2.3 (same as OP).
I am also using ffmpeg 7.1, and errors look very similar to OP . Please let me know if there's any debugging I can help do.

I just did a factory reset and now it works again for me.
The problem was actually lz4. Try removing the lz4 binary at /home/root/lz4 and taking a snapshot.
