我从官方下载的demo,然后解压导入MCUXpresso中,编译没问题,下载没问题
但是debug的时候就显示如下信息:

然后看disassembly窗口信息:
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


但是0xE8这个位置好像没有对应代码函数,求大佬帮忙看看是什么问题~
