JTAG Programming for LPC2138
Started by ●April 22, 2005
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??

Is it a genuine Macraigor Wiggler, or a clone?

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.
