The pinout of the JTAG header on the LPC-Link is given in the "Getting started" PDF guide

Hi unnati,

Please note that the LPC1300 and LPC1100 doesn't have JTAG but SWD only. This is probably not you problem, but is worth while to mention.

Indeed Fig 34 of the getting started guide shows which connections are needed for SWD. Not all pins are needed for the LPC1114, only the SWDIO, SWCLK, RESET and GND are recommended to connect.

Kind regards,
