zynq代码调试 MMU section translation fault

piqiuarm · 发表于 2017-10-23 13:51:35

调试代码发现：
ARM0跟ARM1通信的时候，发现ARM1重启，进入了PrefetchAbortHandler

.section .vectors
_vector_table:
B _boot
B Undefined
B SVCHandler
B PrefetchAbortHandler
B DataAbortHandler
NOP /* Placeholder for address exception vector*/
B IRQHandler
B FIQHandler

反汇编查看： MMU section translation fault
请问这MMU运行有哪些原因会导致这种问题的出现？
