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

766 cd ../Release/C01LBGV01/EC2108Y/
767 ls
768 cd debug/
769 ls -la
770 cd fullapp/
771 ls -la
772 sudo chmod 777 core.6584
773 mipsel-linux-gdb hmw_start.elf -c core.6584
774 cp ../../../../../FullApp/BCM7405/lib/hmw/* lib/hmw/ -af
775 mipsel-linux-gdb hmw_start.elf -c core.6584
776 cp ../../../../../FullApp/BCM7405/lib/hmw/* lib/hmw/ -af
777 ls -la
778 sudo chmod 777 core.6604
779 mipsel-linux-gdb hmw_start.elf -c core.6604

780 pwd
