I tried to downloaded the firmware to ATmega88P by AtmelStudio6.2 and JTAGICE3.
Device Programming setting.
The Interface item choice is "ISP".
An error occurs when I carry out Device signature.
Unable to enter programming mode.
Please verify device selection, interface settings, target power and connections to the target device. Look in the details section for more infomation.
Would you tell me by the solution to this problem.
