Error on xtensa-esp32s3-espidf

[lorenzo-pirchio]

Hi, I am currently working on a project for esp32 in Rust. I followed the instructions of https://docs.esp-rs.org/book/tooling/debugging/probe-rs.html. So I did cargo install probe-rs-tools on cmd and I downloaded probe-rs extention for vscode and I added probe-rs.exe as debugger in the extention settings. I downloaded the esp-idf-template and I added the launch.json file. But when I launch the debug I get this: Can anyone help me? Could it be a problem that I didn't set up the cmake extention? Thanks

This particular error looks like what happens if you set server: yourself in your launch.json, but then don't actually start probe-rs yourself. The port number seems to support this, can you please try either following Connecting to a standalone probe-rs dap-server server or removing server from your launch config?

Other than that, even if you manage to resolve this particular error, our esp-idf support isn't really done (we don't correctly reset Xtensa ESP32s currently) so you might run into other issues.

This is my launch.json.

{
    "version": "0.24.0",
    "configurations": [
        {
            "type": "probe-rs-debug",
            "request": "launch",
            "name": "Launch",
            "cwd": "C:\\prova-debug4",
            "chip": "esp32s3", //!MODIFY
            "flashingConfig": {
                "flashingEnabled": true,
            },
            "coreConfigs": [
                {
                    "coreIndex": 0,
                    "programBinary": "C:\\S3WifiCD\\xtensa-esp32s3-espidf\\debug", //!MODIFY
                }
            ]
        },
        {
            "type": "probe-rs-debug",
            "request": "attach",
            "name": "Attach",
            "cwd": "C:\\prova-debug4",
            "chip": "esp32s3", //!MODIFY
            "coreConfigs": [
                {
                    "coreIndex": 0,
                    "programBinary": "C:\\S3WifiCD\\xtensa-esp32s3-espidf\\debug", //!MODIFY
                }
            ]
        }
    ]
}

I don't set any server and I removed the lines for the reset but I still have the same problems. Everytime I get the error, the port number is different.

Okay thank you. I'm not sure what's going on, maybe @noppej knows how we can get an ECONNREFUSED for a partially supported target 🤔

Also, while this is irrelevant to your issue, "version": "0.24.0" is not correct: the version is related to the launch.json format which should be 0.2.0.

To be sure that I set up the debug environment correctly, I explain all the steps. First of all, I'm using a Windows pc and Esp32S3.

1. I did cargo install probe-rs-tools
2. I downloaded the extension for VSCode
3. I put the path to probe-rs.exe as debugger in the extension.
4. I generated launch.json in my project which is the following: { "version": "0.2.0", "configurations": [ { "type": "probe-rs-debug", "request": "launch", "name": "Launch", "cwd": "C:\prova-debug4", "chip": "esp32s3", //!MODIFY "flashingConfig": { "flashingEnabled": true, }, "coreConfigs": [ { "coreIndex": 0, "programBinary": "C:\S3WifiCD\xtensa-esp32s3-espidf\debug", //!MODIFY } ] }, { "type": "probe-rs-debug", "request": "attach", "name": "Attach", "cwd": "C:\prova-debug4", "chip": "esp32s3", //!MODIFY "coreConfigs": [ { "coreIndex": 0, "programBinary": "C:\S3WifiCD\xtensa-esp32s3-espidf\debug", //!MODIFY } ] } ] }
5. I changed config.toml adding: [target.'cfg(any(target_arch = "riscv32", target_arch = "xtensa"))'] runner = "probe-rs run --chip esp32s3" linker = "ldproxy"

I have a doubt, Do I need to have cmake installed in my pc to use probe-rs?

The programBinary path looks wrong if it's a Rust project, it should point to the actual binary file which is usually in something like target/<architecture>/debug/program(not sure what the architecture for this chip is).

And can you see anything in the Debug Console output in vscode? Something like this:
