如何运用Gdb对ARM板上的程序进行远程调试

新客网 XKER.COM 2007-09-04 来源： kit 收藏本文

在arm板上运行 gdbserver

[root@51Board usb]# ./gdbserver 192.168.0.29:1234 arm0702_8.out

Process arm0702_8.out created; pid = 228

从服务器中等待一个请求

这个是对qte程序的调试，先运行程序再调试进程号。在PC机上程序名称一样的。

// ./gdbserver 192.168.0.29:1234 --attach 545

说明：

这里的192.168.0.29是上位PC机的IP(这个应该于ARM板上的IP在一个网段内)

1234这里规定的端口号，等下要用到的，当然这个也可以用其他的端口号

Arm0702_8.out

上位PC机运行 arm-linux-gdb 调试程序

[root@zieckey collieryMainSrc02]# arm-linux-gdb arm0702_8.out

(gdb)

上位PC机连接到ARM板

[root@zieckey collieryMainSrc02]# arm-linux-gdb arm0702_8.out

(gdb) target remote 192.168.0.50:1234

Remote debugging using 192.168.0.50:1234

0x40001550 in ?? ()

这时ARM板上的信息应该是这样的：

[root@51Board usb]# ./gdbserver 192.168.0.29:1234 arm0702_8.out

Process arm0702_8.out created; pid = 228

Remote debugging from host 192.168.0.29

现在就已经建立其了PC机通ARM板山的连接了。

那么我们就可以像调试本地程序一样调试ARM板上程序。

例如：

(gdb) list

19 //#include "cmaininterfacewidget.h"

20 //#include "headers.h"

22 #include "cwidgetmanager.h"

23 #define _DEBUG_

24 #define _DEBUGCDatabase_

26 int main( int argc, char ** argv )

27 {

28 QApplication app( argc, argv );

(gdb) break 28

Breakpoint 1 at 0xf25c: file main.cpp, line 28.

(gdb) target remote 192.168.0.50:1234

Remote debugging using 192.168.0.50:1234

0x4011dc30 in ?? ()
