I am using Atmel studio6, AvrDragon and custom board which contains at32uc3a0512. Last fourth months i used this same tool for programming and debugging. Recently i purchased atmel jtagice3 and i used it for programming. Again i used avrdragon for programming it just shown error as it below:
"Unable to enter programming mode. The read device ID does not match the selected device or any other supported devices.
Please verify device selection, interface settings, target power and connections to the target device.
