Possible reason and solution:
  1. connect 12v adapter.

  1. The problem is in the SD CARD that is in the interface. I had the same problem and solved it. Programming the sd card for KTAG and KESS is a very difficult process that cannot be done by everyone. There are two options 1. that somebody who knows, do - can program a new sd card or other option to buy SD CARD.

Last but not least, ensure you have one good quality of Ktag clone. i.e SE135-B1 (73.39euro, red pcb), SE135-E (63.22euro, red pcb).
