Question to extension developers:
When jtag uploading will be implemented in official extension?
Uploading via serial port takes to much time.
And in my case, impossible: my device has no serial port on pcb, jtag only
So I cannot use your extension(

Does anybody implemeted this future?

Thank you!

You already got some very helpful answers here:
https://github.com/espressif/vscode-esp ... issues/161
(Actually it looks like this was just approved but you posted much earlier, so sorry for the attitude)

Perhaps a VS Code task that builds and then executes the command provided by pwmb would work for you.

So made jtag-upload task.
Tested under Windows only, but under Unix should work too

Limitation:
OpenOCD must be stopped before lunch this task.

1. Add new task in tasks.json:

Code: [Select all] [Expand/Collapse]

        {
            "label": "Flash - Flash jtag",
            "type": "shell",
            "presentation": {
                "focus": true
            },
            "command": "${config:idf.pythonBinPathWin} ${workspaceRoot}/.vscode/flash_jtag.py",
            "windows": {
                "command": "${config:idf.pythonBinPathWin} ${workspaceRoot}/.vscode/flash_jtag.py"
            },
            "options": {
                "env": {
                    "PATH": "${config:idf.customExtraPaths}",
                    "OPENOCD_SCRIPTS": "${command:espIdf.getOpenOcdScriptValue}",
                    "OPENOCD_CONFIG": "${command:espIdf.getOpenOcdConfigs}",
                    "BUILD_DIR": "${workspaceRoot}\\build"
                },
            },
            "problemMatcher": [
                {
                    "owner": "py",
                    "fileLocation": [
                        "relative",
                        "${workspaceFolder}"
                    ],
                    "pattern": {
                        "regexp": "^\\.\\.(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                        "file": 1,
                        "line": 2,
                        "column": 3,
                        "severity": 4,
                        "message": 5
                    }
                },
                {
                    "owner": "py",
                    "fileLocation": "absolute",
                    "pattern": {
                        "regexp": "^[^\\.](.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$",
                        "file": 1,
                        "line": 2,
                        "column": 3,
                        "severity": 4,
                        "message": 5
                    }
                }
            ]
        }

2. Create and put "flash_jtag.py" file into .vscode folder

Code: [Select all] [Expand/Collapse]

import subprocess
import os
import json
 
oocdScripts = os.environ["OPENOCD_SCRIPTS"]
oocdConfig = os.environ["OPENOCD_CONFIG"]
buildDir = os.environ["BUILD_DIR"]
 
oocdScripts = oocdScripts.replace("\\", "/")
builoocdConfigdDir = oocdConfig.replace("\\", "/")
buildDir = buildDir.replace("\\", "/")
 
cmd = "openocd.exe -s " + oocdScripts + " " + oocdConfig
 
with open(os.path.join(buildDir, "flasher_args.json")) as f:
    flasher_args = json.load(f)
 
for addr in flasher_args["flash_files"]:
    cmd = cmd + " -c \"program_esp32 " + buildDir + "/" + flasher_args["flash_files"][addr] + " " + addr + " verify exit\""
 
cmd = cmd + " -c \"reset\""
 
# Comment this, if exit from OpenOCD not needed
cmd = cmd + " -c \"exit\""
 
print("Executing:\n" + cmd)
print("")
 
os.system(cmd)

Yes because the task need to connect via openocd to upload bins
