How to set up a Zephyr Project App in VSC? - visual-studio-code

Question

I am trying to use VSC to develop and debug embedded C applications with Zephyr OS. Is this possible? Are there instructions to set this up? Is there a zephyr setup extension? The Zephyr documentation discusses how to debug apps on eclipse, and there is an eclipse/zephyr plug-in, but I'd prefer to use VSC if possible.
Since Zephyr utilizes CMake, I thought I follow the VSC CMake project tutorial. When it asks to select a kit, there was nothing appropriate for zephyr, so I left it with no active kit selected. With this setting, I am actually able to get a successful build for the blinky example but cannot debug the project. The error I get is:
ERROR: Unable to start debugging. Unexpected GDB output from command
"-exec-run". Don't know how to run. Try "help target". The program
'/home/mustafa/Code/Sycamore/hello_world/build/zephyr/zephyr.elf' has
exited with code 42 (0x0000002a).
If anyone has any input on how to address this error or instructions on setting up a zephyr project in VSC, that would be great. Thx!

Only few steps enough:
Add necessary folders to workspace like:
"folders": [
{
"path": ".",
"name": "app"
},
{
"path": "..\\zephyr",
"name": "zephyr"
},
{
"path": "..\\mcuboot"
},
{
"path": "..\\modules\\hal\\stm32"
}
]
Install Cortex-Debug extension
Setup debug session in file .vscode/launch.json:
"configurations": [
{
"name": "App",
"cwd": "${workspaceRoot}",
"executable": "./app/build/zephyr/zephyr.elf",
"request": "attach",
"type": "cortex-debug",
"serverpath": "C:/Program Files (x86)/SEGGER/JLink/JLinkGDBServerCL.exe",
"servertype": "jlink",
"device": "stm32f412RE",
"interface": "swd",
"svdFile": "./STM32F412.svd"
},
{
"name": "Bootloader",
"cwd": "${workspaceRoot}",
"executable": "./boot/build/zephyr/boot.elf",
"request": "launch",
"type": "cortex-debug",
"serverpath": "C:/Program Files (x86)/SEGGER/JLink/JLinkGDBServerCL.exe",
"servertype": "jlink",
"device": "stm32f412RE",
"interface": "swd",
"runToMain": true,
"svdFile": "./STM32F412.svd"
}
