pyocd 0.36.0, VS Code and Zephyr

[rtborg]

I'm using pyocd 0.36.0 and STM32F303K8Tx. My VS Code launch configuration is:

{
	"name": "Launch Nucleo F303K8",
	"device": "STM32F303K8Tx",
	"cwd": "${workspaceFolder}",
	"executable": "build/zephyr/zephyr.elf",
	"request": "launch",
	"type": "cortex-debug",
	"runToEntryPoint": "main",
	"servertype": "pyocd",
	"gdbPath": "${userHome}/zephyr-sdk-0.16.5-1/arm-zephyr-eabi/bin/arm-zephyr-eabi-gdb",
	"preLaunchTask": "West Build",
	"showDevDebugOutput": "both"
}

The output I get when launching is below:

And the terminal tab output:

GDB server session ended. This terminal will be reused, waiting for next session to start...

When running west debug, everything seems to work fine, but I want to get debugging working from VS code.

I think you need to specify the target. Add these lines to launch.json:

      "serverArgs": [
        "-t", "STM32F303K8Tx"
      ],

I'm assuming that you've already have the cmsis pack installed. If not, also install it by executing pyocd pack install STM32F303K8Tx
