gdb+gdbserver求指教
介绍一下我开发中遇到的问题:arm-uclibc-linux-gcc 编译器
主机 IP : 192.168.1.224
目标机 IP : 192.168.1.223
通过nfs把host下的temp目录mount到target目标板子上mount下，可执行文件hello放在主机目录temp下.
->在目标机上使用gdbserver 192.168.1.224:2345 /mount/hello
提示:
Process test created; pid = 476
Listening on port 2345
->在主机上使用arm-uclibc-linux-gdb /temp/hello

在目标机上面提示:

求教问题出在哪里，是TCP参数需要重新设置一下吗？ # gdbserver --debug --remote-debug :3456 /mount/hello

(gdb) gdbserver发送数据包
$T050b:0*"00;0d:403ea0be;0f:c0090040;thread:1dc;core:0;#f7
gdb接收数据包
$T050b:00000000;0d:403ea0be;0f:c0090040;thread:1dc;core:0;#f7
由于数据包0b后面的几位出错,导致checksum的时候提示错误的数据包,估计是这个原因导致 主机这边没有指定调试的程序吧？你试着在target remote之前先执行
file /temp/hello
