SAM4S2a Connecting to debugger

Mon Jun 29, 2015 10:19 am

Hi all,

I have my user board with SAM4S2A without external clock , when I want to start write a HEX file to SAM4S2A via Atmel studio 6.2 and SWD BUS so I can not connect to MCU, even read the ID of MCU. Any possible solution? Must be there external clock?

Thank you for reply
