Debugging on Visual Studio Code doesn't work

[naftilos76]

Hi everyone,

My workstation is a linux mint 20.3 box.

I have visual studio code 1.65.2 installed.
I have installed all prerequisites through the esp32 plugin.
I have a ESP32-rover-kit dev board ver 4.1 .

I have installed openocd : Open On-Chip Debugger v0.11.0-esp32-20211220 (2021-12-20-15:42)
I had to create udev rules file. I created a file named 90-esp32-rover-kit.rules and i appended the following line of text:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6010", GROUP="plugdev", MODE="0666"
I added the "0403" & "6010" based on the data i saw from a lsusb command results.
I used the command "sudo udevadm control --reload-rules && udevadm trigger" to reload udev rules.

When i launch opencd i can see the following in the tab "OUTPUT":

Open On-Chip Debugger v0.11.0-esp32-20211220 (2021-12-20-15:42)

Info : starting gdb server for esp32.cpu0 on 3333

So far i can build / flash & monitor just fine using the UART or JTAG.

My launch.json file has the following:

{
"version": "0.2.0",
"configurations": [

{
"type": "espidf",
"name": "OpenOCD",
"request": "launch",
"debugPort": 3333,
"logLevel": 2,
"mode": "manual",
"verifyAppBinBeforeDebug": false,
"tmoScaleFactor": 1,
"initGdbCommands": [
"target remote :3333",
"symbol-file /build/interrupts-test.elf",
"set remote hardware-watchpoint-limit 2",
"monitor reset halt",
"flushregs",
"thb app_main"
],
"env": {
"CUSTOM_ENV_VAR": "SOME_VALUE"
}
}
]
}

When i reach the point where i click on the button "Run & Debug" (Ctrl+Shift+D) i can see some activity in the tab "OUTPUT" which looks like this:

*This follows after the line "Info : Listening on port 3333 for gdb connections" given above.

Warn : keep_alive() was not invoked in the 1000 ms timelimit. GDB alive packet not sent! (1315 ms). Workaround: increase "set remotetimeout" in GDB

I tried adding "set remotetimeout 10" in my launch.json but that doesn't seem to work.
Although i have created one or more breakpoints i see nothing that indicates execution having stopped at any of my breakpoints.

Can any one help?

Thanks and regards
