J-Link EDBG unable to connect to target

The Atmel SAM C21 Xplained Pro requires some special handling inside the J-Link EDBG firmware to work correctly. This for example includes the handling of some additional buffers etc. that have been added to the target interface of EDBG on this board.

This special handling has been added in the J-Link EDBG firmware from 16-04-26. Please make sure that this or a later version of the firmware is used. For more information about how to get the latest firmware and how to replace the Atmel EDBG firmware with a J-Link EDBG firmware, please refer to our website: https://www.segger.com/jlink-edbg.html
