Good morning brilliant people.
I have a custom board I am trying to program with Atmel-ICE but Jtag seems to only be halfway working and by that I mean in Atmel Studio 7 under device programing the tool shows up and I'm able to select the device and apply but if I try to read the voltage it fails and if I try to read the device signature it reads the voltage and fails saying no Jtag devices are present.
I have a MEGA-1284P Xplained board for testing that I can hook up and read the device so it isn't the programmer.
I suspected cable issues so I have short snips of wire soldered to the breakouts for the Jtag and connected directly to the squid cable that I tested on the Xplained board which got me this far.
The VCC and GND are still a bit long but the roundabout voltage reading in Atmel Studio is stable at 4.8VDC.
I hope I'm just tired and am missing something simple but any ideas and information is greatly appreciated.
