大佬们，我先描述一下问题哈~我官方下载的NXH3670的demo，解压导入MCUXpresso。
编译和下载没问题，但是debug的时候直接飞了~
报错信息如下：

可以看得出来在加载0x0000CB10 地址的时候就已经开始失败了~
然后看汇编窗口显示：
000000e8: Failed to execute MI command:
-data-disassemble -s 232 -e 340 -- 3
Error message from debugger back end:
Cannot access memory at address 0xe8
000000e9: Connection is shut down
看的出来在0xE8这个位置出现问题，没有办法连接过去~
这个位置我找不到对应的代码，也实在是不清楚怎么解决~
