The ICE showed it had power(center red LED on) and the target had power (left Green LED on). Studio gave message 'Failed to launch program', 'Error: Target power not connected. I disconnected the 10 pin female IDC with squid and moved it to the new small ICE adapter board, and pointed Studio/project/tools to it.īoth MK II and ICE are to used with the JTAG interface for advanced debug over an ISP interface. I bought a second new smaller AT-ATMEL-ICE. I have a Studio V7 with a ICE Mk II and mega2560 with a squid cable running fine for years on win 10.
