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:

TODO: Add correct dmesg output here...

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.

Create a file named openocd.cfg with following contents:

TODO: add correct configuration file here.

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
