Loading SVD from Device Support Pack

[dwalkes]

Hi,

Thanks for sharing this project!

I'm attempting to use with Renode and this launch configuration on this test project:

        {
            "showDevDebugOutput": true,
            "cwd": "${workspaceRoot}",
            "executable": "./build/bluepill-starter.elf",
            "name": "Debug Renode",
            "request": "launch",
            "type": "cortex-debug",
            "servertype": "external",
            "preLaunchTask": "Build STM",
            "gdbTarget": "localhost:3333",
            "device": "STM32F103"
        }

Then manually starting Renode using the instructions here.

set bin @<path to working directory>/bluepill-starter/build/bluepill-starter.elf
s @scripts/single-node/stm32f103.resc
machine StartGdbServer 3333

I'm able to use interactive debug, however I haven't been able to come up with the correct settings for the device parameter to load the svd file, despite the fact that I"ve loaded the STM32F1 device support pack. Each time I see No SVD File Loaded: undefined. If I replace the device attribute with:

            "svdFile": "./STM32F103.svd",

Where the .svd file is taken from this link the peripherals view works.

I'm wondering how I should specify the device argument to get it to find the svd file so I don't need to specify it myself as a workaround.

The README link to https://marcelball.ca/projects/cortex-debug/ is down for me today, perhaps it would be explained there.

Thanks for sharing and for any suggestions you have to resolve this.

I am assuming you installed the support pack in vscode, which btw, I am not sure is being maintained. You can see the entire support pack here.

Btw, did you try "device": "STM32F103xx". I believe it is expecting two alpha-numeric chars after the device's major type. The device setting is also used for other purposes and it needs to match to a real device

Btw, it is safer to use the svdFile setting to specify. In your case, since you are using an external gdb server, the device setting is not really used for anything else. Getting the svd file direct from the MCU vendor is what I highly recommend.

There can be bug fixes in SVD files that you may not be getting if you get files distributed by others. Just a suggestion

Thanks for the response!

I did.

I did not, but I confirm this does work.

Thanks for the advice!
