embedded arm development - gdb doesn't connect to openocd and returns monitor errors

[TerryFogg]

Visual Studio 15.9.4 openocd 0.10.0 STM32F769I-DISCO board.

Cannot start debug session, error "monitor\" command not supported by this target.\n"

I have captured the following log of the debug session. I get the error "monitor\" command not supported by this target.\n"

This is the same error you get at the gdb command line if you type "monitor" without first submitting the following command "target remote localhost:3333"

I can't see any place in the log below where this occurs?

Any help appreciated.

@yuehuang010 @paulmaybee could you take a look?

[TerryFogg]

I re-read my issue, and I see I didn't mention I was using Visual Studio 2017 edition with a CMake project and a launch.vs.json file

[TerryFogg]

Of course, this may not be the correct place to raise this issue?

[paulmaybee]

can you attach you launch.vs.json?

[yuehuang010]

If you started the server manually first, then try using starting GDB. Does that help?
