调试嵌入式设备时 core文件 在哪里？

[wang@wang shellscript]$ /usr/local/arm-linux/bin/arm-linux-gdb -q
(gdb) file /home/wang/master/master.exe

(gdb) q

[wang@wang shellscript]$
然后在设备上只有/proc/sys/net/core
本地文件夹 shellscript 和/home/wang/master里面 都没有 /usr/local/arm-linux/bin 里面也没有
怎么回事？

没人鼓捣嵌入式？

Segmentation fault. 后面没有 core dump 是不是因为这个？那应该用什么方法查找此处的错误？
