Serdar,
Your jtag speed is set too fast. The segger driver 3.10d will help a
lot. You can also set the speed to fixed at 1000, assuming your CCLK
is 12mhz or better. These are set in the JLink selection in Options.
Hope this helps

Hi everyone,
I obtain the following message when i try to download the code with J-Link;
"Could not identify firmware(identification string has length of 0)"
or
"Received 0xFFFFFFFF as core Id.
No communication with core"
I checked all J-Link connections and LPC pins.
I use;
MCU : LPC2131
Comp: IAR 4.30A
I hope someone can help me.
Have a nice day,
