生成core的调试方法

1. telnet到STB启动U盘listen
./hmw.sh


2. 
mount -o nolock -o proto=tcp 192.168.23.71:/home/qinshijun/liguowang/core /mnt/usb7
ulimit -c unlimited
echo /mnt/usb7/192-168-23-108-core-%e-%p-%t > /proc/sys/kernel/core_pattern


3. 
killall -11 hmw_start.elf 主动生成core


cp ../../../../../FullApp/BCM7405/lib/hmw/* lib/hmw/ 拷到对应的目录可以得到更多的调试信息


/home/qinshijun/liguowang/c20/Software/Release/C01LBGV01/EC2108Y/debug/fullapp/lib
