Installation
Ubuntu/Debian packages
Openocd 0.5 is a recommendation of the paparazzi-dev package, install it if not already done so. For older distributions (Debian squeeze, Ubunutu Lucid, Maverick and Natty) backported packages are available in the Paparazzi repositories. See Installation. The latest paparazzi-arm-multilib packages also already include gdb for arm.
from source
The low level interfacing is done by libftdi, get it from http://www.intra2net.com/de/produkte/opensource/ftdi/ It is possible to use a closed source version from FTDI, too. Probably more recent version available?
wget http://www.intra2net.com/de/produkte/opensource/ftdi/TGZ/libftdi-0.10.tar.gz tar xvfz libftdi-0.10.tar.gz cd libftdi-0.10 ./configure make make install
Get the OpenOCD software http://openfacts.berlios.de/index-en.phtml?title=Building_OpenOCD It needs some additional packages to be built. Not on berlios anymore...
apt-get install autoconf apt-get install automake apt-get install subversion svn checkout svn://svn.berlios.de/openocd/trunk cd trunk ./bootstrap ./configure --enable-ft2232_libftdi make make install
For some debian distributions you might have to add '/usr/local/lib' to /etc/ld.so.conf.d/i486-linux-gnu.conf and call
ldconfig
Configuration
STM32
GDB needs to exactly know the target architecture and OpenOCD currently does not automatically hand GDB all the needed details. You will need a xml file with the target description, save it and load it in your .gdbinit:
set tdesc filename ~/path/to/gdb_cortex_m3_target.xml
For lisa/m boards file lisa-m.cfg should look like:
# the Lost Illusions Serendipitous Autopilot # http://paparazzi.enac.fr/wiki/Lisa # Work-area size (RAM size) = 64kB for STM32F103RB device set WORKAREASIZE 0xFA00 source [find target/stm32f1x.cfg]
LPC21xx
Generate an OpenOCD config - this one worked, might need some polishing

This .gdbinit should start gdb in the correct way for the lpc21xx:
#set directories $cdir:$cwd:../lcds16x2/ set can-use-hw-watchpoints 2 set complaints 33 set history save set history size 333 set logging on set output-radix 0x10 set step-mode on set trust-readonly-sections on set verbose on set watchdog 15 target remote localhost:3333 monitor soft_reset_halt # only for RAM: monitor arm7_9 sw_bkpts enable monitor arm7_9 force_hw_bkpts enable hbreak main #load #continue
