You might not get a reply but usually the turnaround time is < 24 hours.
If it's not let me know and I'll find out who to ask.

I’m getting same error even if I debug on the same device.

necktwi@pi:/home/necktwi/Workspace/RemoteDebugTest/build$ lldb-server-6.0 
platform --listen "*:1234" --server
Connection established.

necktwi@pi:/home/necktwi/Workspace/RemoteDebugTest/build$ lldb-6.0

I think it’s a bug. I tried to sign up for bugs-ad...@lists.llvm.org

Re: [lldb-dev] error: process launch failed: Lost debug server connection

[Ted Woodward via lldb-dev]

FYI - the color you picked for this makes it unreadable against a white 
background. I had to convert it to plain text to read it.

 

The error message “Lost debug server connection” occurs if the platform isn’t 
connected and it is not a host platform.

 

What do you get if you type “platform status” after “file Test”?

 

Is the remote-built executable available on your Mac? lldb will need it to be 
able to get symbols and debug info.

Why the process launch failing? The executable `Test` takes parameters `-s 
normal`. How to feed them in? Did the process failed because of not feeding its 
arguments?
