    • Segger J-link GDB server lost connection to the target and debug session has been terminated.

      I'm using a J-Link Base with Eclipse trying to load/debug a Kinetis K64F board.
      Mostly it works extremely well, however...
      It very often fails to program the device and I get the error dialog below.
      Sometimes I have to power-cycle the device and retry a dozen times, other times it just works.
      Any hints as to what might be causing this intermittent behavior?
      Its very painful!
      Thanks in advance,
      Best Regards, Dave

      PS: Windows 10, JLink_Windows_V722b driver/gdb/firmware package installed.
