For a debug environment, I am using OpenOCD with a Wiggler-clone JTAG interface. The following steps worked for me with a 20081028 OpenOCD snapshot. GENERAL STEPS: 1. Check out OpenOCD svn checkout svn://svn.berlios.de/openocd/trunk openocd 2. Build OpenOCD Read the INSTALL file from the files you just downloaded. You probably just need to run: ./bootstrap Then configure OpenOCD using the configure script created by ./bootstrap. ./configure --enable-parport Build OpenOCD with: make Install OpenOCD. Since we used the default configuration the code will be installed at /usr/local/bin/openocd. Other files will be installed at /usr/local/lib/openocd (configuration files, scripts, etc.) and /usr/local/share/info (online documentation accessable via 'info openocd'). You need root priviledges to do the following: make install. 3. Setup OpenOCD reads its configuration from the file openocd.cfg in the current directory when started. You have two different options: * Create a symbolic link named openocd.cfg to one of the configuration files in /usr/local/lib/openocd, or * Use a custom configuration file specified with the ‘-f <conf.file>’ command line switch opeion when starting OpenOCD. For the STR-P711, I have included bash scripts in the scripts sub-directory. 4. Running OpenOCD Make sure the ARM7TDMI board is powered and the JTAG cable is connected Run 'src/openocd -d' (might be required to be root) and check for any errors reported. The '-d' option enables debugging info. 5. Telnet interface telnet into port 4444 to get a command interface: 'telnet localhost 4444' 6. GDB start arm-elf-gdb type 'file <executable.elf>' to load the executable type 'set debug remote 1' to enable tracing of gdb protocol (if required) type 'target remote localhost:3333' to connect to the target The same commands from the telnet interface can now be accessed through the 'monitor' command, e.g. 'monitor help'
