一、问题背景
粉丝在进行 ARM-A 系列软件编程时遇到以下问题，串口打印这段日志后就重启了，粉丝求助问是什么原因？

0x210: 0x0000000000000000这里主要将发生问题时的相关的寄存器 dump 出来，包括通用寄存器 x0 ~ x29，EL3/EL1 模式下的控制寄存器和状态寄存器以及 GIC 相关寄存器。
首先我们要了解 EL3 模式是系统里最高的运行模式，EL1 模式（linux 内核运行的模式）发生的严重异常会陷入到 EL3 模式中，这些异常包括内存非法访问、指令非法访问等。
2.1 ESR 寄存器分析
在生发问题时，EL3 的错误状态寄存器 ESR_EL3 会报告异常的类型等信息，这个寄存器也是异常症状诊断的寄存器，我们先看看这个寄存器的格式：
里面 EC（31：26） 域是错误代码， 这个案例里 esr_el3 为 0xbe000011，对应的值为 0b101111（0x2f），对应值解释为：
即发生了 SError，需要看 ISS 部分的编码来具体分析。SError 是系统错误的意思，通常是发生了异步异常，通常来自 external aborts。那我们继续看 ISS[24:0]，我们这里 ISS 值为 0x11。
由上图不难发现，系统是发生了异步异常，异步通常是说异常同步在错误发生的同时抛出的，而是有一段延迟，比如在关闭中断情况下发生的 data abort，就会在开启中断后触发，表现为异步异常。所以，ESR_EL3 寄存器给我提供的信息就是这些。
2.2 SError
通常有三种类型的 SError：
- 内存访问经过 MMU 检查，但是在内存总线上遇到了问题。可能是内存映射错误，访问了不存在的地址
- 内存或者 cache 的 ECC 校验失败，通常是硬件问题
- 将 cache 中的脏数据写回到外存中
2.3 错误返回地址
通过 elr_el3 = 0x0000000000b99d84 可以看出，EL1 发生问题的程序地址为 0x0000000000b99d84，我们也能看到不同 cpu dump 出来的信息是一致的，这个地址需要将 Linux 内核反汇编来查看在哪里。
2.4 错误访问地址
FAR_EL3 记录了发生同步异常时，访问的数据或者指令的虚拟地址。但是由于这里发生的是异步异常，所以没有参考价值
建议
1.再截取更早的错误日志
2.查找内核中关于内存映射部分的修改
