Hello,

A prefetch abort usually means that you are accessing a memory address that is out of range. To trouble shoot, you need to have a look at your CPU registers to see the content of the LR register when in the offending function. Most likely, this is caused by an uninitialized pointer, by using more than the allocated space for an Array, or by a stack corruption issue of some kind.
