debug without download. #559

Closed XIVN1987 closed 2 years ago

XIVN1987 commented 2 years ago

Every time starting debug, cortex-debug will download executable to mcu flash. How start debugging without download?

my cortex-debug configuration:

    "type": "cortex-debug",
    "name": "Cortex Debug",
    "cwd": "${workspaceRoot}/ports/m480",
    "executable": "./build-M482Lite/micropython.elf",
    "runToMain": true,
    "request": "launch",
    "servertype": "pyocd",
    "targetId": "m487jidae",
    "svdFile": "./M481_v1.svd",

Terminal output:

You'd use a "request": "attach" to debug an already flashed device without re-flash (and restarting - although you can manually restart the code once connected).
