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 approximately 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 the other led (green) blinking.
Next 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 configuration should automatically find the correct default 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 TODO: add some more stuff here
