One new trick for an old dog

Well... There is no much trick in the ten pin 0.05" (1.27mm) ARM JTAG/SWD connector, but it is definitely new for "an old dog" - LPC2103.
A few weeks ago I received several small 0.85 x 1.26" (23 x 32mm) LPC210x header boards from BatchPCB. OpenOCD version 0.3.1 with FTDI2232 based adapter does work with LPC2103 on the board via new tiny JTAG connector. However, the OpenOCD configuration file needs minor adjustment since the connector has no TRST pin. So the reset configuration should include srst_only to let the OpenOCD know that TRST is not available.
