Debugging an Application 6. At the GDB prompt, connect to the IXP1200 target: target remote IXP1200_ipaddr:port_number 7. At this point, the program is running and you can begin using the debugger. — Type list to see the code. — After setting a breakpoint, type continue (not run). For more information on how to use GDB, see publicly available GNU tool documentation. 34 Compiling and Testing Applications Revision 3.3, August 2001
Chapter 4 Configuring and Starting IXA Systems This chapter describes how to start an IXA system with a particular port configuration and launch the application’s system ACEs, library ACEs, and user ACEs. This chapter contains the following topics: l “Overview” on page 35 l “Using Startup Scripts and Configuration Files” on page 36 l “The System Configuration File” on page 37 l “Setting Up Particular Configurations” on page 39 l “Launching Application ACEs” on page 46 Overview Typically, you start the system software automatically as part of booting the IXDP1200 Advanced Development Platform. To do this, you call a startup script, which in turn calls other scripts. The scripts use configuration files, which you modify to configure your application’s port usage and to load, configure, and start the system, library, and user ACEs for your application. The default system initialization startup script (SDKinstallpath/bin/armbe/ixstart) loads the IXA SDK components and drivers and sets up the necessary Linux * device entries. It then runs the configuration utility ixconfig. This utility reads the system configuration file, SDKinstallpath/bin/arm-be/ixsys.config. l l You must modify the system configuration file to configure the ports and interface ACEs. The script starts the interface ACEs. See “Using Startup Scripts and Configuration Files” on page 36. You must specify any microACEs you want to start in the system configuration file, and specify where to find the compiled microcode images for your application. The script starts the microengines and the microACEs. Revision 3.3, August 2001 Configuring and Starting IXA Systems 35
