I am making a custom circuit based upon the SAME70 and I'm trying to program it via Atmel-ICE via SWD protocol.
Even if all connections are correctly set, I can't get Atmel-Ice communicating with the uC, I constantly get an error message saying: "No device detected. Error 4109"
I have tried erasing via the ERASE pin as well as adding all passive components to stabilise the circuit according to the datasheet.
I suspect the uC is set by default to use a different communication method/interface then the SWD but I can't find any clear info.
Can anyone kindly help?
