Hi @Aravindpb​ 

 

The issue may be due to

  1. JTAG header pins. Check your jtag header pins for ground short or misplacing it.
  2. Power supply. check the power supplies and its connection are following the recommended values as stated in the respective device handbook. 
  3. pull-up & pull-down connected to the JTAG pins are following the recommended values as stated in the respective device handbook.
