主机系统为windows xp，用虚拟机安装了红帽linux9.0，开发板为优龙公司出的YL9200V2.0
用linux下的minicom实现主机与开发板的通讯
现在实现了通过nfs方式将主机上的/home挂载到开发板上的/tmp目录下
/home中有gdbserver，hello，hello.c三个文件，hello为主机中用命令：arm-linux-gcc -o hello hello.c生成的
在开发板上输入命令：./gdbserver 192.168.0.7:2345 hello
出现以下信息：
Process hello created: pid = 825
Cannot exec hello: Permission denied.
Child exited with retcode = 7f
Lisitening on port 2345
然后在主机上输入命令：arm-linux-gdb hello
出现信息如下：

This GDB was configured as "--host=i686-pc-linux-gnu --target=arm-linux"...hello: 没有那个文件或目录.
(gdb)
然后输入：target remote 192.168.0.100:2345
出现提示如下：
Remote debugging using 192.168.0.100:2345
Remote communication error: Connection reset by peer.
在开发板上出现信息提示如下：
Remote debugging from host 192.168.0.7
Child exited with status 127
GDBserver exiting
这应该是没有成功吧？怎么回事呢？
注：192.168.0.7是主机IP，192.168.0.100是开发板IP
