I am using S32K144 IC.

Connected external crystal with - 12Mhz.

Initially the code is flashed, after changing clock registers one time only flashed.

After that I am getting the following error while flashing the code by IAR IDE with I-Jet debugger.

"session aborted-unable to connect to CPU"


When i am performing JTAG test with target board the attached error message is showing.

But I connected JTAG connections as per S32K144EVB-Q100 board J14 connector.


Please suggest what I have to do to solve this problem.


Thanks & Regards,
