Arduino uno r3 operates on digital pins on 5v. Standart jtag use 3.3v(some devices supports 5v - if not or not enabled you will burn device connected to arduino or maybe even arduino itself). It device jtag not supports onlu 3.3v voltage you need to use proper arduino or modify current(some tutorial on internet). Also check if all pins excluding gnd have 3.3v voltage.
