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.

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.

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

Put an entry with the vendor/device ID into your udev rules directory to get the correct access rights (or use the file from cvs in conf/system/udev/rules). This applies to Amontec JTAG-Tiny.

add 'BUS=="usb", SYSFS{idVendor}=="0403", SYSFS{idProduct}=="cff8", GROUP="plugdev"' 

Generate an OpenOCD config - this one worked for me, might need some polishing

#daemon configuration

gdb_port 3333

flash bank lpc2000 0x0 0x7D000 0 0 lpc2000_v2 0 12000 calc_checksum

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


Unzip the Eclipse embedded CDT from Zylin for embedded debugging http://www.zylin.com/embeddedcdt.html There probably are more up-to-date versions available ;-)

wget http://www.zylin.com/embeddedcdt-linux-gtk-20060908.zip
wget http://www.zylin.com/zylincdt-20060908.zip
cd eclipse
unzip embeddedcdt-linux-gtk-20060908.zip
unzip zylincdt-20060908.zip

Now you have to get used to Eclipse, read this using the LPC2148 examples: http://www.yagarto.de/howto/yagarto2/index.html
