RTOS Support

I've figured out how to get the debugger to run for an ESP32 project, but OpenOCD is not configured for RTOS. I can clearly see in the log that it specifies "rtos none". I need it to specify "rtos auto". 

Does anyone know how to alter the GDB startup params in the Adruino plugin for Visual Studio?

Attached is the program build output.
The debug startup output is also attached.

I found the ESP32_RTOS flag set to 'none' in the _vm xml file
...Projects\ESP32RET\__vm\Configuration.Debug.vmps.xml
Changed the ESP32_RTOS set to 'auto', but the debug start output still shows it as 'none'. Not clear where debug start is getting its settings.

Thanks.

The _vm folder just shows what happened. The properties are read live from generic config files.

Normally when we switch on show build properties that also switches on verbose compile which shows which tools are actually used for the build. Your output has verbose switched off for some reason.

The debug output suggest this tool pattern is being used:-

tools.openocd.debug.args={params.verbose} -l "{{build.path}/{build.project_name}_DebugOpenOCD.log}" -s "{path}/share/openocd/scripts/" -f "{path}/share/openocd/scripts/interface/{build.openocddebugger}" -c "adapter_khz 5000" -c "set ESP32_RTOS none" -f "{path}/share/openocd/scripts/board/{openocdscript}" {initCmd}

You can redefine any of the patterns shown in the build properties by adding a text file to the root of your project called board.txt.

Then redefine specific patterns by adding them to that file. The next build/debug will use the redefined pattern(s)

Does this help?

Thanks Tim. I'll try that.

Can you tell me how RTOS debug mode is decided for a board? Where could I find this setting?

Its not. It defaults to off.  No testing has been made.

Just to note on this the value for ESP32_RTOS is the name of the RTOS running on the target.

If you remove the -c "set ESP32_RTOS none" part of the command it will default to "FreeRTOS" which is the default for the ESP32 version of OpenOCD.

More detail about the ESP32 specific variables can be found here: 
https://github.com/espressif/openocd-esp32/blob/master/espressif.md

To override the setting for the S3 USB Debugger in use, try the below entry in a local board.txt:
tools.esps3usb.vmserver.args={params.verbose} -l "{{build.path}/{build.project_name}_DebugOpenOCD.log}" -s "{path}/share/openocd/scripts/" -c "set ESP_FLASH_SIZE 0" -f "{path}/share/openocd/scripts/interface/{build.openocddebugger}" -c "set ESP32_RTOS none" {initCmd}
