Introduction

Installation Instructions

Look for the package named openocd in the Synaptic Package Manager and install it.

Usage examples

Using OpenOCD with Olimex ARM-USB-OCD and LPC-H2103

OpenOCD Setup

After installing OpenOCD package, you need to set permissions right. Create a file ""/etc/udev/rules.d/45-ft2232.rules"" with following contents:

BUS!="usb", ACTION!="add", SUBSYSTEM!=="usb_device", GOTO="kcontrol_rules_end"

SYSFS{idProduct}=="0003", SYSFS{idVendor}=="15ba", MODE="664", GROUP="plugdev"

LABEL="kcontrol_rules_end" 

Then connect ARM-USB-OCD to the USB port. Check ""dmesg"" which should give the following output:

[  347.868034] usb 2-2: new full speed USB device using uhci_hcd and address 3
[  348.172550] usb 2-2: configuration #1 chosen from 1 choice
[  348.360463] usbcore: registered new interface driver usbserial
[  348.360496] USB Serial support registered for generic
[  348.360556] usbcore: registered new interface driver usbserial_generic
[  348.360561] usbserial: USB Serial Driver core
[  348.525815] USB Serial support registered for FTDI USB Serial Device
[  348.526020] usb 2-2: Ignoring serial port reserved for JTAG
[  348.526109] ftdi_sio 2-2:1.1: FTDI USB Serial Device converter detected
[  348.526155] usb 2-2: Detected FT2232C
[  348.526250] usb 2-2: FTDI USB Serial Device converter now attached to ttyUSB0
[  348.526277] usbcore: registered new interface driver ftdi_sio
[  348.526282] ftdi_sio: v1.4.3:USB FTDI Serial Converters Driver

Connect ARM-USB-OCD dongle to LPC-H2103 prototype board via JTAG cable.

Power on LPC-H2103 board by giving 5 volts between Vin and gnd pins. Refer to board schematics for correct pins ( http://www.olimex.com/dev/pdf/lpc-h2103-pins.pdf ). The board should now have power led (red) on and another led (green) flashing.

You need to create a configuration file. More information here: http://openfacts.berlios.de/index-en.phtml?title=OpenOCD_configuration

The file can be named for example openocd.cfg, and the contents of that file:

source [find interface/olimex-arm-usb-ocd.cfg]
source [find target/sam7x256.cfg]

This should automatically find the correct configurations for the board and for the dongle.

Start OpenOCD daemon with the following command:

openocd -f openocd.cfg

TODO: Add output here

Test the setup by connecting to openocd daemon with telnet:

telnet localhost 4444
