机顶盒死机抓堆栈

标清：

 ulimit  -c unlimited
   ./skapp
   ./gdb  -c core.1800  ./skapp

高清：

因为生成的堆栈文件比较大，所以建议在U盘下运行。

1、拷贝一个没有strip的skyapp 、gdb-arm-hisiv200-linux到U盘。没有strip是没有压缩的意思。

2、按e退出skyapp，ulimit -c unlimited,打开core限制，运行skyapp 挂机后会生成一个core的文件。

3、挂载U盘，在U盘里执行skyapp。

4、死机后运行./gdb-arm-hisiv200-linux ./skyapp ./core  

5、运行bt指令

e

#Exit skapp ...
