Debugging User Applications

Overview

This document describes how to debug user applications under PetaLinux.

The GDB debugger (and Insight graphical interface) is available for

debugging applications on the MicroBlaze Linux target. To do so, it is

first necessary to build the gdbserver helper application. gdbserver runs

on the MicroBlaze, and acts as an interface between GDB running on the

host, and the target application.

The debug scenario is illustrated in Figure 1.

Figure 1 PetaLinux Application Debugging Overview

Assumptions

The following assumptions were made in the preparation of this tutorial:

 Basic familiarity with the PetaLinux development methodology

 Existence of a working PetaLinux MicroBlaze system, including

TCP/IP networking

Building the gdbserver application

Before debugging applications, the gdbserver helper tool must be built.

Gdbserver is a standard application provided as part of the PetaLinux

distribution. Enable it in the PetaLinux menu-configuration process as

follows:

Start the Kernel config tool.

$ cd $PETALINUX/software/petalinux-dist

$ make menuconfig

Select the Customize Vendor/User Settings menu

┌────── Kernel/Library/Defaults Selection ──────

Save and Exit from the menu.

Under the Miscellaneous Applications menu, select the gdbserver option.

└──────────────────────────────┘

Save and Exit from the menu.

Make sure the application you wish to debug, is also selected. Build and

boot the system in the usual manner.

Debugging on the Target

On the MicroBlaze system, use the gdbserver application to launch your

application

# gdbserver host:1234 /bin/myapp

Process /bin/myapp created; pid = 50

Listening on port 1234

This tells gdbserver to listen on TCP/IP port 1234 for a remote debugging

connection. You can pass any parameters to your application by appending

them to the gdbserver command line, e.g:

# gdbserver host:1234 /bin/myapp param1 param2 param3 …

Next, on the host development workstation, change into the directory where

the application was built, e.g.

[host]$ cd $PETALINUX/software/user-apps/myapp

Among the files in this directory, will be a file myapp.gdb - this is a

special version of your application that helps the gdb debugger to work.

Launch the application debugger:

[host]$ microblaze-uclinux-gdb myapp.gdb

When debugging applications, you must use the special version of the gdb

debugging - `microblaze-uclinux-gdb`

Do not confuse this debugger with the "standalone" MicroBlaze debugger,

`mb-gdb`.

GDB will start, and present a window similar to Figure 2.

Figure 2 MicroBlaze Linux application GDB start screen

Next, select File Target Settings from the main menu. This will open the

Target Settings Dialog box. The settings must match those shown in Figure

3 below, except for the IP address field, which must correspond to the

IP address of your MicroBlaze target board (192.168.0.10 in this example).

Finally, press OK to close the Target Settings dialog box.

一本好书。照着做了一下，可以编译成功，但是下载到板子上没法用。我用的是XUDPVTLX110T大学计划板，和文档中的不一样。我是在VMware虚拟Ubuntu下编译的，用Licence时出了一点麻烦，因为不能修改其中的HostID，只好改网卡的ＭＡＣ地址，但虚拟机不支持全部ＭＡＣ地址修改，最后只好用Linux网卡配置命令来修改，而且每次用的时候都要改。奇怪的是，我在家里和单位的电脑上改ＭＡＣ的效果不一样，因为编译时还要连接到petaLogix公司的网站。

根据里面讲的步骤来做，是可以弄出来的
