What is gdb doing here that it wants to read the target's memory?
(gdb) si
Cannot access memory at address 0xeafffff4
(gdb)
Cheers,

Can it be that it's reading the next instruction?

Probably. This is ARM; most ARM debugging stubs do not offer a
single-step operation, so without hardware singlestep we need to read
the current PC in order to determine the next PC.
