dap-debug fails unless kicked by external process.

[ReggieMarr]

I'm trying to debug some C code with the following registered template:

  (dap-register-debug-template
        "Zybo"
        (list
        :type "cppdbg"
        :name "ZYBO launch"
        :request "launch"
        :cwd "${workspaceFolder}"
        :program "${workspaceFolder}/myprogram.elf"
        :MIMode "gdb"
        :miDebuggerPath "/opt/software/Xilinx-ARM-toolchain-2017.2/SDK/2017.2/gnu/arm/lin/bin/arm-xilinx-eabi-gdb"
        :miDebuggerServerAddress "fedora:3000"))

Then I see the following message show up (which btw I cannot trace down exactly where this comes from)

Warning (emacs): Initialize request failed: Unable to start debugging. Unexpected GDB output from command "-target-select remote fedora:3000". Unknown remote qXfer reply: OK Disable showing Disable logging

Additionally I also see this in the out buffer:

It seems as though the sessions drawer has gotten kicked and my cursor moves to some file but the line isn't highlighted as it normally would be and I can't use dap-next or similar commands.

Then if I attempt to start a debugging session from the terminal like so:

repos/zybo-apps [ /opt/software/Xilinx-ARM-toolchain-2017.2/SDK/2017.2/gnu/arm/lin/bin/arm-xilinx-eabi-gdb -ex 'target remote fedora:3000' myprogram.elf

Remote debugging using fedora:3000

The dap-session gets "reactivated" in the sense that the session drawer is active, my cursor is placed on another line.

This is pretty puzzling behaviour to me so any help debugging is much appreciated.
