Cannot start the debugger

Just updated the VSCode and PIO including all platforms. Now I have the issue that the debugger won’t start I get the following:

.pioinit:11: Error in sourced command file:
Remote communication error. Target disconnected.: Success.

I also get a Visual Studio Code dialog popup stating:

Failed to launch GDB: .pioinit:11: Error in sourced command file:
Remote communication error. Target disconnected.: Success. (from interpreter-exec console
“source .pioinit”)

So, what does “.pioinit:11: Error in sourced command file:” mean??

If it previously worked and now it doesn’t, open an issue about the regression in Issues · platformio/platform-espressif32 · GitHub

@maxgerhardt Thanks for the response!

Not sure if it is a pio bug - I spend some time experimenting this evening and found that if I ‘Erase Flash’ first the debugger starts and break at the app_main() as it should. The strange thing is that I now and then need to erase the flash or the debugger don’t start correctly, so maybe it’s my HW (NodeMCU)?

After testing and experimenting with the OLIMEX ARM-USB-OCD-H jtag debugger I found that if the error occurs ,as described in this post - one need to erase the flash by help of the PIO menu ‘Erase Flash’.
Also if you have problems with not being able to set break point(s), check if the Vcc on the JTAG connector (pin 1 or 2) is connected to the development board, if it is then remove it. Doing so removed all the break point issues I had on the NodeMCU development board.
