GDB server fails to start

Target is FRDM-KL27Z .

Running on Windows 7, 64-bit

Kinetis Design Studio, Version: 3.2.0

GNU ARM PEMicro Interface Debugging Support 2.6.0.201610062322

Trying to launch debugger using OpenSDA USB, I get an error:

Followed by:

I'm not sure if it's a hardware problem with my target board or an installation problem with the SDK, or other...???

Any help/feedback would be appreciated.

Thanks.

Have you checked if there is not another instance of the P&E GDB server running? See https://mcuoneclipse.com/2014/11/03/debugging-failure-check-list-and-hints/ and https://mcuoneclipse.com/2015/05/18/gdb-client-and-server-unlocking-gdb/ .

I hope this helps,

Erich

Yes. There is no other copy of the server running. It appears to be a misleading error message. I think the real problem is not being able to connect to the target.

This was a hardware issue. Several jumpers (J5,J6,andJ7) were missing. These jumpers isolated the OpenSDA USB from the MCU. The host could still see the OpenSDA processor, but couldn't get to the MCU. The gdb server launch failure was just a side effect.
