This indicates that the memory access does not follow alignment requirements, which differ according to the memory attribute of the region:
This means that if a region is configured as “Strongly Ordered” and you try to do an Un-Aligned Memory access, an Alignment Data Abort occurs. The Memory Map of the Cortex R5 has address range 0xEFFFFFFF to 0xFFFFFFFF configured as “Strongly Ordered” by default.
