配置 gdbserver 调试程序

sayou678

gdbserver + gdb 调试 arm-linux system, Malformed packet(b)
我用 c+ gdb 调试 arm-linux system, gdb-7.0.1
Compile gdb ./configure --host=i686-pc-linux-gnu --target=armv5tl-montavista-linux-gnueabi --prefix=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le
Compile gdbserver
CC=/opt/mv_pro_5.0/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc ./configure  --host=armv5tl-montavista-linux-gnueabi --prefix=/home/liyg/DBVT/ipnc/target/filesys/

5                  printf("goodbye gdbserver!\\n");

==========================================
请问问题出在哪里？

版本没有问题，调试其他程序（包括多线程程序）没问题，这个程序涉及多进程，再板子上直接gdb调试没问题，就是gdbserver远程调试出问题，我想用图形界面调试，所以不想直接在板子上跑gdb
