Hi,
I recently upgraded the ESP32 toolchain from 5.2.0/7.10/r12 to r16. Unfortunately all my projects made in Visual Studio witch Visual GDB broke down. The paths are broken and a lot of other errors are popping out. I think that could be due some path changes from previous versions of ESP IDF. I use the most up to date Visual GBD version.

So I decided to make a new ESP-IDF project and in the beginning I need to choose from CMake and GNU Make sample. I chosed the recommended CMake. The entire solution builds successfully.
My board is a simple ESP32 board connected through standard USB simulating a COM port on my PC. I know there is no debugging functionality for that but I would like just to program the flash.

In Visual Studio I’m clicking on the Start buttno which previously started to build and program the solution into the flash of my board, but now every time I try I get this error:

What should I do to program the ESP32 using the regular USB connection without any JTAG?
