I am evaluating visual GDB. We will buy once it is working for us.

Trial version in use.

My hello world project debug works.

Platform : Windows 7

Visual studio 2015.

Olimex ARM-UDB-OCD-H is attached to SD card to Esp32 Wrover.

using latest ESP32 master branch.

Debug Test does not work as well.

also command gdb not working.

but

I am getting this error with my project.
