I have tried to program a fresh/new LPC2138 using Wiggler and Cross Studio 1.4. After creating a new project and copying a sample program I have built the code. But unable to initialize JTAG port (The message is "Cannot identify target. Check JTAG connections and that the target is powered". The chip was powered and JTAG connection was correct. What may be the possible reason for this?? Sudip

The wiggler I am using a cloned one. RTCK(24) is pulled down using 4.7K resistor, TRST(20) is pulled high by 4.7K. 16MHz and 32.768KHz crystals are connected properly. Sudip Leon Heller <leon.heller@...> wrote:
